Currently displaying Days, Hours, Minutes.
Change this to Months if Days > 30.
Perhaps hide hours and minutes.

Verify:
The filter has less than a month left of the schedule, a warning alarm has been triggered.
This has triggered ALARM C in HA.

Check if the register address is correct or if the actual filter alarm won't trigger until the counter has expired.

Will have to wait until I have created or found a good automation for detecting when Both are at work.
Only trigger once,

Hello @Ztaeyn,

sorry that I am disturbing you.
I have paste your yaml file and fitt the ip adress as you said. I am able to send the data to VTR300, but I dont receiving a data from it.
I am using as @cmragnar a Waveshare https://www.waveshare.com/w/upload/8/86/RS485-TO-ETH-B-user-manual-en-v1.1.pdf to manage the data. I am sitting since days and I am little bit frustrated. I dont have IAM and Save Touch panel. I am stearing my VTR with a help of Save Light.
Thank you for your help in advice.

Best regards,
Chris

Thanks for your work!
Modbus address 12102 is used twice, both for "climates" and for "sensors". This fails in HA 2024.3, and only the climates one is being used by HA, not the vsr300_supply_temperature (Entity not availble).

Changes made 2023-12-29

added sensors for fan speed at all levels

added control of normal fan speed, supply and exhaust individually

added unique ID to all entities: switches, inputs, helpers and sensors

Unique ID enables adding the entities to one or more areas.

save_vsr_300_textformat.txt

Persistent Notification for the filter replacement.
Phone notification to admin if an alarm triggers.

Goal: Create as one automation.

Hi,

I know this code has been created by numerous hands, but do you know anything about the entities:
- name: vsr300_calculated_moisture_extraction
address: 2210
- name: vsr300_calculated_moisture_intake
address: 2211
they are not documented in the Systemair's documentation, yet they are actually showing something...

Also, these 2 registers have incorrect addresses

  - name: vsr300_efficiency_temperature
    address: 12107
  - name: vsr300_overhetingstemperatur_tilluft
    address: 12108

They should be -1

Found another one:
in vsr300_mode_status: separate Cooker and Hood? They should be:
{% elif states('sensor.vsr300_mode_status_register')|int == 7 %}
Cooker Hood
{% elif states('sensor.vsr300_mode_status_register')|int == 8 %}
Vacuum Cleaner
{% elif states('sensor.vsr300_mode_status_register')|int == 9 %}
CDI1
{% elif states('sensor.vsr300_mode_status_register')|int == 10 %}
CDI2
{% elif states('sensor.vsr300_mode_status_register')|int == 11 %}
CDI3
{% elif states('sensor.vsr300_mode_status_register')|int == 12 %}
Pressure guard
{% else %}
WTF
{% endif %}

Thanks for your work!

When Trykkvakt is running, changing Fan Speed/Mode does not update which function is running.
Added a button to display Trykkvakt is running.

Solution can be to set switches to read "current mode OR current mode + trykkvakt"

Check if input value matches sensor value for setpoint.
Modify color of text, or display a symbol if these match, instead of displaying - both values.

Awaiting a PPM sensor.
