nilan's Issues

Concurrent connections on ModbusRTU from different integrations - read errors

I'm not sure if this is a issue with the integration or with HA DataUpdateCoordinator, so clarifying will be helpful.

I have a one Modbus serial bus, with multiple devices on it. It's connected to HA via USB-RS485 adapter.
There is 2 integrations which using Modbus RTU, one is Nilan, the other is native Modbus Integration built in a HA which reads all other devices on the bus.
Update interval for both is set to 30 sek.

When HA starts and run, both integrations tries to read registers from different devices at the same time. It resulting in communications errors and unavailable sensors.

My workaround for this is to disable Nilan integration manually and observe the led's on usb adapter. When led's stops flashing (native Modbus integration is done with serial bus for now), I'm enabling Nilan after few seconds. In that way I have those 2 integrations shifted in time with theirs readings, and everything working well.... until next HA restart.

Support for VPL 25

Hello,

I have a VPL25c with a CTS602 board with old push button display. I believe this is very similar to VPL 15c which is already supported by this integration.

I replaced the CTS600 with a CTS602 - 512 motherboard back in 2021, to get Modbus interface. The board runs sw version 2.37.C. I've used a Modbus TCP adapter by the name of Hi-flying elfin EE11 (RS485 to ModBus TCP) to control VPL25c manually up until this point and has been working fine. But I would very much get it nicely integrated to Home Assistant

When I try to add it this integration to home assistant with the ip address it says device not supported. How can I help to get this VPL28c supported by this integration?

Add Sync Entity for Time

Hello, just updated to 2023.09.b0 to test and got the below error. I am unable to clearly determine what the core issue is, but perhaps you can ?

Automations

Should one still be able to run following type of holding register services even your perfect HACS is active? Looking to build Nordpool sensor triggered automations w/o python skills, but e.g. below service does not turn PILP off:

service: modbus.write_register
data:
address: 1001
slave: 30
value: 0
hub: hub1

Nilan EC9 with CTS 602

Hey I have this Nilan EC9 with CTS 602 and got your setup working now nicely but few question still pops to existence:

I can set the Nilan: Top Water Heater (Electric) from the GUI but could not do any automations to it, is it just me or is it missing from the code. I used Kimmo Hyvönen's original python examples and with that I can set it manually by running that python script.

Other thing I was looking for is to set the Bottom water temp to control the compressor and room intake to control cooling/ventilation/heating as CTS 602 seems not to have away to control them directly. All this I can do with my own script.

Any helps is greatly appreciated.

nilan: Error on device update!

@veista - thanks so much for adding support for my Nilan. Got it all up and running, nice dashboard etc - great stuff!

I get 8x errors in the logs on startup. I seem to be getting other data through ok, but wanted to let you know.

Seems to be related to the below ...
get_supply_heating_pid_time
get_compressor_stop_time
get_low_temperature_compressor_start_setpoint
get_max_return_step
get_min_supply_step
get_central_heat_type
get_central_heat_select
get_air_heat_select

I don't seem to have similarly named entities created.

Please let me know if I can help, or get further logs etc etc - very happy to help! 😀

Upgrade to 2023.7 core breaks Nilan connection

I have Nilan EC9 with CT602 mobus v22 connected to HA (Core 2023.6.3) through Waveshare RS485-to-Eth working as intended. When I upgrade to 2023.7 series core something breaks and connection between HA and Nilan is lost. The issue is replicable and connection returns when reverting to 2023.6 core from backups.

Failed to call service

Issue is that services water_heater.turn_off and water_heater.turn_on cannot be called with Developer Tools. Also automations related to these services are not working. Still tough water heater can be turned on and off from dashboard. Workaround for this issue for me would be possibility to change water heater target temperature but that seems not to be an option in automations menu. Any idea what could cause this?

Unable to add integration

Unable to add integration. Is it necessary to edit configuration.yaml manually, I just don't know how?

Feature request

Hi,

For a newbie, any suggestions on how to customize your code to also capture Nilan Compact version with 602 control ?
I guess it should be simple to add the relevant input and holding registers that are added for the water heating.
The product
https://www.nilan.no/produkter/ventilasjon-med-oppvarming/ventilasjon-varmtvann-og-oppvarming/compact-p-air9
The Modbus mapping.
https://www.nilan.no/Files/Files/Norsk/Download/7.%20Modbus%20-%20BACnet/2021-01-Modbus_CTS602_w_HMI350T_Modbus.pdf

The newbie tip would involve how to customize and install manually instead of using HACS.

Idea of enhancement: Soft buttons and display replacement va modbus

Hi again,

The actual text displayed on the CTS602 panel is transmitted over modbus at the following input addresses 2002 to 2011:

I had that working just fine over MQTT. So I could read exactly what what printed on the panel at the system, which is in a cabinet. Avoiding having to open the cabinet to verify, and was a good way to check immidate effect of the change of state etc...
So I added it here:

Now also, key press can be written here at the following holding addresses:

That part I never managed to make work over MQTT.

But if both worked here, we could create buttons in lovelace reproducing exactly the panel and calling for service for modbus writing reproducing exactly the panel on a UI, and also having the whole complete menu available from HA.

That would apply/work for all Nilan presumably...

I could help working on this, but I might need a couple of pointer to have the text sent over the integration, and the method to write keypresses to holding reg.

If you think it is not useful, feel free to close the issue, and I might give it a long shot on my own as a fork.

Use integration with USB-RS485 interface

Hi,
I would interested in trying out this component.

Currently I use a USB-RS485 stick with the Homeassistant modbus integration (https://github.com/StefanUG/nilan-hass-modbus/tree/master)

Would it be difficult to make it able to use the serial connection?
Thanks in advance!

Configuration guidance for Sharewave Ethernet-to-RS485 converter

Hi,

My setup:

Nilan EC9 / CTS602
Waveshare RS485 TO ETH (B) converter https://www.waveshare.com/wiki/RS485_TO_ETH_(B)
Raspberry Pi 3 + Home Assistant
Nilan integration installed from HACS

I get "Invalid Response from Device" when trying to add the integration. Any ideas where the problem would be?

The modbus integration used to work in Openhab and previous USB-converter but I changed to ethernet-based for this specific integration in HA.

Unsupported device (Comfort 300 LR Light HMI/Waveshare RS485 to ETH (B)

Hello

Thanks for your great work, I am very much looking forward to finally getting my HVAC online at some point.

I've been struggling with getting the plugin to connect with my Comfort 300 however. I've already been over all the wiring, termination etc. I have an powermeter online on the bus as well (PME3250) and I've measured correct voltage levels and "activity" on connection terminals at the plug on the HVAC unit itself. So, im fairly confident that this issue has to solved on "the software side".
Im using the waveshare, and pasting in my config at the end just for reference.

I hope the info supplied below is what you need, or else please let know. Thanks again.

CTS700 - what is needed?

Ive currently added my Air 9 with CTS700 through modbus into HA with the network cable attached to the system.
Currently i'm mapping each adress (Mine is a none geo version).

What is needed to add support for CTS700 too?

Mine is currently added to HA:

`modbus:
  - name: nilan
    type: tcp
    host: 192.168.2.217
    port: 502
    sensors:
      - name: nilan_humidity
	# Current humidity
        address: 21776
        unit_of_measurement: "%"
        slave: 1
      - name: nilan_t20_outdoor_temperature
	# Outdoor unit temperatur
        unit_of_measurement: "°C"
        slave: 4
        address: 20688
        count: 1
        scale: 0.1`

etc. etc.

Some data is placed at slave 1 (Indoor unit), and the outdoor unit data is placed on slave 4 for instance.
Latest ModBus guide i could find is dated back in 2018, but seems to be working somewhat atleast.

After the last update, I have two nilan integrations at once. Other times it didn't work, maybe there's a bug somewhere?

All sensors show same name

Not nice - is this a feature of this integration?

entity ids for adding sensor to cards are like:

'Invalid response from device'

Trying to create serial connection to Nilan, but getting error "invalid response from device".

Setup

HA on Raspberry PI 4
CTI USB-Nano-485 Interface Converter (connected to HA USB0)
Nilan CTS602 with SW 2.38

...any thoughts?

Modbus forwarder

Hi, do you have any experience with modbus forwarder? Your extension works pretty well until I try change for example top boiler temperature. The value is not changed in HA, but also it looks like sometimes there is an error on forwarder and sometimes there is no error. I am using modbus2usb for years but currently I have some time to create forwarder to allow connect HA to Nilan. Whereas the forwarder is so simple I am not sure where should I take a look. Do you have any hint? Thanks

Home Assistant 2023.9 broke Nilan integration - "Failed to set up"

Hey @veista - hope you're well!

Just raising this one as it seems that Home Assistant 2023.9 has broken my Nilan integration. 😢
It was working fine before the update, wouldn't start up after the update.

I'm getting the below in the logs.

Is there more information I need to add to help here?
Debug logs etc?

This error originated from a custom integration.

T4 sensor

Hi, I have a feeling if there is an error with the "Waste Air Temperature" display on the Combi 302 model. As the sensor.py file has the same name for the T4 and T6 sensors.
It is precisely the data from the T4 sensor that I am missing. You can look at it? Thank you.

Nothing works at all after the last update.

After Upgrade Re-Installation raises an error

Hi,

have upgraded to version 1.2.3 running on HA 10.5 with 2023.8.3.

I've Nilan integrated via Serial, which was working now for a while.

Now after the HACS Upgrade, restart of HA and unplug/plug of Nilan USB, I've clicked on "Add Integration" and have selected the Interface type "Serial".

Normally next step is the selection of the usb path but now the system is throwing a popup with title "Fehler" without any further information.

Enabling log, restart HA and trying same to find this in the system log.

Any idea how to solve it?

Doesn't work with 2023.9?

After updating to version 2023.9 of Hass, the integration couldn't find any entities? Worked before without issues, but after the update the entities were on state unavailable. After completely deleting the nilan integration and a reinstall, the integration has a setup failure, and no entities are added. The USR-TCP settings haven't been changed en is still connected to the network. (Same port) Rebooted my network (unify), my USR and home assistant, but nothing works..

Fresh install of 1.2.3 yields "IndexError: list index out of range" when accessing registers

I've done a fresh install of version 1.2.3 into my Home Assistant 2023.7.3. Installed by unzipping the Github release zip file. Communicating with a COMBI 302 T over Modbus-TCP.

The installation itself went fine from a UI perspective (no errors reported, although all the detailed sensors took a while to appear). However, there are a few IndexError entries in the log:

VP 18cek: Additional holding registers

Would it be possible to add holding registers:

Output.CenCircPump | 118 | EK circulation pump | VGU-VP
Output.CenHeat_1 | 119 | EK heater relays | VGU-VP
Output.CenHeat_2 | 120 | -- | VGU-VP
Output.CenHeat_3 | 121 | -- | VGU-VP

It would show user which central floor heating relays are on and if the circulating pump is on.

Also I think the VP 18CEK should also be able to show:
Input.T13_Return | 213 | 100 | °C | EK return temperature | VGU-VP

It gives user feedback how much heat has been lost during the circulation

Integrating VP18cCom via RS485 serial USB

Hi,

I'm trying to connect my Nilan VP18cCom via RS485 serial USB with HA (using also CTS602).
I'm getting the error message "Unsupported Device" during the integration of Nilan.

I'm new at HA, the same interface was working before via PI and Node Red.
I've added this into configration.yaml and restarted HA:
# Logger logger: default: critical logs: custom_components.nilan: debug custom_components.hacs: debug

But I'm still unable to see any log entries in Log-book. Have also activated debug protocoll for the HACS device.
Here is my selection:

As the path seems to be correct:

Add Language Support

Add proper support for different languages.

Time betw.de-icing

Please add Time between defrosts. This option is available in the HMI. Thank you.

No Response received from the remote unit/Unable to decode response

Hi,
Currently on 1.1.1B, and since release 1.0.25 I have after many hours of perfect function and error as follow:

Logger: homeassistant.components.modbus.modbus
Source: components/modbus/modbus.py:391
Integration: Modbus (documentation, issues)
First occurred: 05:58:02 (1 occurrences)
Last logged: 05:58:02

Pymodbus: Nilan: Modbus Error: [Input/Output] No Response received from the remote unit/Unable to decode response

And then all entities generate an error like this one:

Logger: custom_components.nilan.device
Source: custom_components/nilan/device.py:2204
Integration: Nilan (documentation, issues)
First occurred: 05:58:02 (988 occurrences)
Last logged: 08:42:34
Could not read get_time

Reloading the integration does not fix it.
Restarting Hass core does not fix it.
To make it work again I need to reboot the bridge and then reload the integration.
Then it work flowlessly for some 8-10 hours and crashes again...

I will try now to revert to pre-1.0.25 and see over long time if it occurs again...

My device is Comfort series we just added to the supported devices.
This did not occur before 1.0.25 ( in the beta versions we tested before).

Unsupported Device: VPL 15

Debug log:

Error importing config flow

Hello,

Wanted to take the fresh 2022.2.0b1 today, after installing it i get the following error:

Logger: homeassistant.config_entries
Source: config_entries.py:1211
First occurred: 08:33:14 (1 occurrences)
Last logged: 08:33:14

Error importing platform config_flow from integration nilan to set up nilan configuration entry: No module named 'pymodbus.client.sync'

So the integration does not load.

Tried redownloading the custom integration, and restart again, but not improvement.
Reverted to 2023.1.7 and it works again just fine.

Do you know of a major change of pymodbus in the upcoming HA updates ?
I could find similar issues reported in earlier upgrade of HA here:
https://github.com/WillCodeForCats/solaredge-modbus-multi/issues/162

And I can see that in 2022.2, core pymodbus bumped to 3.1.1.
https://github.com/home-assistant/core/pull/86513
I will try to change that in the manifest and see if that works.

Not sure if it is the same reason. Also home assistant now requires python 3.10 minimum, not sure if related.

Translation Help

If you are a native speaker of any language not yet supported or want to improve the translations, please do so and leave a pull request.

You can use the en.json Translation File as a template.

Thank You!

P.S. Please note that not all translated lines, such as entity names show up yet in the HA frontend.

Defrost ventilation level

Hi. Query. When setting the defrost ventilation level to "none", I think the unit does not respond. Is it a feature that the fans work even during defrost or is it a bug?

Hey there, thanks for your work on this integration.

I've tried to install, and I'm getting a device not supported error.

Believe from a previous post that this is what you need from the debug logs? If you need more, please let me know - will be very happy to help.

New Device Nilan Comfort 300 (Top)

Hi,
I think I got the Modbus bridge running, and now I get an error when trying to set up the integration through config flow.
"invalid response from device".

I checked the logs, on debug mode and there is no entry for the custom integration. I suspect it is due to an unsupported device.

Any idea ?
I do not have HMI panel. Only CTS602.
Item No.: "71104F", Model: "Comfort 300 Top" from year 2015

Nilan <-> Waveshare RS485-ethernet <-> HA Nilan integration 'failed to connect' error.

Hi again and sorry for bothering with stupid questions (perhaps)

My setup:
Nilan EC CTS602
Waveshare RS485 TO ETH (B) converter https://www.waveshare.com/wiki/RS485_TO_ETH_(B)
Raspberry Pi 3 and Home Assistant running in container
Nilan integration installed from HACS

When trying to add integration, I get 'Failed to connect' error:

I've managed to set up my waveshare converter (or at least I thinks so):

Loggin gives following:
'2022-12-20 00:14:37.435 ERROR (MainThread) [pymodbus.client.sync] Connection to (192.168.1.200, 502) failed: timed out'

I'm quite sure that this has something to do with my waveshare configs? First I thought that this problem is caused by running HA in container and mapping not workin between container and host. But then found out that Host <-> HA running in container have all the ports opened as a 'default' I guess.

When loggin in to my router settings, I can see waveshare IP in the ARP/RARP Table.

Perhaps some of you who has managed to get this integration work with waveshare could help. All the help is highly appreciated and hopefully even rewarded in the end.
