Python library for Yeelight's bedside (btle) and candela lamps

Python 100.00%

python-library yeelight home-assistant bluepy

python-yeelightbt's Introduction

Python library for Yeelight Bedside lamp

This library allows controlling Yeelight's bluetooth-enabled bedside lamp and Candela devices.

Note that this library is not actively maintained, however, patches are very welcome.

Candelas support only setting the light on and off, and adjusting the brightness.

Currently supported features:

State
Color mode (white, color, flow)
Temperature
Brightness
Sleep, wakeup & scheduling (partially)

Installation

pip install git+https://github.com/rytilahti/python-yeelightbt/

In case you are getting "No such file or directory" error for bluepy-helper, you have to go into bluepy's directory and run make there. It is also a good idea to let the helper to have capabilities for accessing the bluetooth devices without being root, e.g., by doing the following:

setcap cap_net_admin,cap_net_raw+eip bluepy-helper

And then simply try if the scanning works. You can use pass '-dd' as option to the command to see the debug messages from bluepy in case it is not working.

Usage

Try

$ yeelightbt --help

and

$ yeelightbt [command] --help

For debugging you can pass -d/--debug, adding it second time will also print out the debug from bluepy.

Finding supported devices

$ yeelightbt scan
Scanning for 5 seconds
Devices found:
  f8:24:41:xx:xx:xx (XMCTD_XXXX), rssi=-83

Reading status & states

To avoid passing --mac for every call, set the following environment variable:

export YEELIGHTBT_MAC=AA:BB:CC:11:22:33

$ yeelightbt

MAC: f8:24:41:xx:xx:xx
  Mode: LampMode.White
  Color: (0, 0, 0)
  Temperature: 5000
  Brightness: 50

$ yeelightbt temperature

Temperature: 5000

$ yeelightbt color 255 0 0
Setting color: 255 0 0

Home Assistant support

This repository also contains a basic Home Assistant custom component.

Yeelightbt installation on Home Assistant (for Raspberry Pi)

SSH into the host through port 22222 to get all necessary privileges (follow setup there). /!\ Using the SSH add-on will not work, it gives access to port 22. Use Putty for instance:

ssh [email protected] -p 22222

You will be logged into the Home Assistant command line interface and type login to access the host system.

Access the bash:

docker exec -it $(docker ps -f name=homeassistant -q) bash

Yeelightbt requires bluepy and the installer may not find where it is located. Therefore, navigate to the package:

cd /usr/local/lib/python3.7/site-packages/bluepy

Install as mentionned above:

pip install git+https://github.com/rytilahti/python-yeelightbt/

Ensure the light is ON and the switch is on the bluetooth position (at least for the Candela). Detect the supported devices and check if the lamp can be turned on/off with the commands described above.

Custom Component Installation

Copy yeelight_bt directory located under custom_components over to ~/.homeassistant/custom_components/.

Configuration

light:
  - platform: yeelight_bt
    devices:
      Bedside:
        mac: 'f8:24:41:xx:xx:xx'

Limitation

With the current custom component version, Home Assistant may lose the connection with the devices after a few minutes or hours. Home Assistant has to be restarted to reestablish this connection

Workaround for Home Assistant

As the custom_component for Home Assistant seems not to be working, I came up with this workaround for using the Candelas.
It is slow and far from perfect, but it works.

1- Install python-yeelightbt using SSH in port 22222 (as described in the Installation section of the documentation) or using Portainer to access the shell.

2- Still in the SSH or Portainer shell, configure your lights:
2.1- make sure your Candela is turned ON (light up) and near
2.2- use yeelightbt scan to list your devices
2.3- try to connect to each Candela using this command yeelightbt --mac:the_mac_of_your_candela on
2.4- it will ask you to change the brightness. CHANGE THE BRIGHTNESS turning the light glass. If you don't, the link will work for a while and stop working later. If you don't see a "we are linked" message, it did not work. Try again.
2.5- repeat 2.3 and 2.4 for every Candela you have.

3- Create multiple command switches in your configuration to operate the Candelas:

switch:
  platform: command_line
  switches:
    candela_1:
      command_on: '/usr/local/bin/yeelightbt --mac=f8:24:41:XX:YY:ZZ on'
      command_off: '/usr/local/bin/yeelightbt --mac=f8:24:41:XX:YY:ZZ off'
      friendly_name: Candela Living Room
    candela_2:
      command_on: '/usr/local/bin/yeelightbt --mac=f8:24:41:XX:YY:KK on'
      command_off: '/usr/local/bin/yeelightbt --mac=f8:24:41:XX:YY:KK off'
      friendly_name: Candela Bedroom
    candela_3:
      command_on: '/usr/local/bin/yeelightbt --mac=f8:24:41:XX:YY:PP on'
      command_off: '/usr/local/bin/yeelightbt --mac=f8:24:41:XX:YY:PP off'
      friendly_name: Candela TV room

Use those switches to turn on/off your candelas.
You can also set brightness to turn it on at a specified brightness setting, so, if the Candela is turned off, running '/usr/local/bin/yeelightbt --mac=f8:24:41:XX:YY:ZZ brightness 100' will turn it on at 100%.

ImportError: No module named construct

from Construct developer, a note

I am the developer of Construct (a parsing library) since I took over the project 2 years ago. Please refer any other projects that also use this library to this post, or copy it over to them.

Construct is undergoing heavy changes at the moment, similar to those between 2.5->2.8, including addition of compiler feature (to make it much faster than Kaitai), but also several classes are going to be removed (for a good reason), and also few were added. API will be unstable for about a month.

What you can do:

All scheduled work is posted as tickets, in Issues and also on Kanban page. If you subscribe (watch repository) then you will have advance notice of any incoming changes. Unfortunately those tickets also include minor work items, so you would get some clutter notifications too. I appologise for that.
I encourage everyone to browse those tickets, vote for feature requests, but also post objections for planned removal of features, or changes in semantics. Subscribing therefore is recommended.
You can find what was already changed (at any moment) on Transition page, which is like a growing changelog. It gets updated whenever something gets added or removed, but since the order is not chronological, new items do not end up on top or bottom of the list.
You can find currently available classes and semantics on revamped Core API pages. Those pages are very extensive and always uptodate with the implementation.
Feel free, at any point in time, to open a new Issue and ask questions or make complaints about breakage. At minimum, I can offer advice and possible alternatives. People very often use the classes in ways that were not designed for, like use String classes to process Bytes.
Feel free, at any point in time, to open a new Issue and request changes. If you need a new class, and make a good clear case, I would be more than willing to add it to core library to support your project.
API should be stable within a month, so either do version pinning and deal with it then, or keep fixing your code at every release (which is ~3 day cycle at the moment).

Close this topic at your discretion.

Multiple lamps

Hi,

First of thanks for the effort, it was rather huge surprise to see this rather exotic product get implemented to home automation.

But I have rather strange issue. I have two bedside lamps and it seem the yeelight_bt server can connect only to one of them in rather random order. I've been able to reproduce same issue in cli as well.
Please find attached logs:

No module named 'yeelightbt'

Hi,

I'm running hassio and i'm unable to make it work. After placing the Yeelight_BT.py file inside the custom_components and set the details into the configuration.yaml i get an error:

ERROR (SyncWorker_14) [custom_components.yeelight_bt.light] Got exception: No module named 'yeelightbt'

I can't use pip install as i'm running hassio so i'm out of ideas of how to make it work

Anybody know how to solve it?

Thanks in advance

Error message

hey,
everything seems fine when install, but can't succeed to make it works...
thanks

Hass io installation

Could a hass io repository be added for simple (no root access required) installation?

Without this I don't think it is easy to install this component. (Hass io only grants access to a virtual environment with home assistant preinstalled)

Integration yeelight_bt not found when trying to verify its light platform

When I try check config in Home assistant it show this error
"Integration yeelight_bt not found when trying to verify its light platform"

I tried to place the component in custom_components/light/ and custom_components/yeelight_bt/light
but that doesn't help

Home Assistant version is 0.96.3

I have a problem with my installation. When i run yeelight from console, all is ok, i got responses and i can toggle lamp on and off.

Scan is made but no connect

Hello @rytilahti
I managed to run this code on Debian 11, Phyton 3.9 and I even can do scan and find my lamp, however when I try to connect and ON / OFF it I get errors:

Everything works from HA for a while... then connection drops

Hi!
This is the issue regarding Candela from HA: after restarting HA (docker container) everything works perfectly for a while. Then it seems that bluetooth connection drops and works again just restarting HA (I guess because of initialization).

This is the error:
Updating yeelight_bt light took longer than the scheduled update interval 0:00:30
5:22 PM helpers/entity_platform.py (WARNING) - message first occured at 5:04 PM and shows up 35 times

System: home assistant from a docker container (hassio) on a raspberry pi model 3+
Issue with Candela

I've seen that in the custom component keep_connection is correctly set to True.

Could you help me?
Thanks,
Federico

which file should i copy to custom_components?

which file should i copy to custom_components? and what's the directory structure after copy?
thank you!

ImportError: No module named main

I'm trying to run this lib on Raspberry Pi 3, but getting an error message:

Traceback (most recent call last): File "/usr/local/bin/yeelightbt", line 9, in <module> load_entry_point('python-yeelightbt==0.0.1', 'console_scripts', 'yeelightbt')() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 356, in load_entry_point return get_distribution(dist).load_entry_point(group, name) File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2476, in load_entry_point return ep.load() File "/usr/lib/python2.7/dist-packages/pkg_resources.py", line 2190, in load ['__name__']) ImportError: No module named main

What am I doing wrong?

Ha plugin installation consulting

Again, I've got the MAC address from other sources, is it still possible to complete the previous steps to make the HA plug-in work, or just fill in the correct yaml can be completed. I had a question about the OSX installation plugin before

The Candela pairs every time

Hey,

Nice work!
I have a little question. I want to use your code to integrate some Candelas with the Domoticz Home Automation System.
But from the moment I send the command it takes around 7 seconds for the Candela to receive it.
This is probably because the Candela doesn't stay connected all the time but it pairs every time I send a command.

Is there any way to make it faster? If I use this in a home automation system it's kinda strange to touch a switch and eat some popcorn while the light will turn on at some moment.

The code is very nice!

yeelightbt got error, is it due to phyton version2?

I am lake of using phyton, please kindly advise

Question about light temperature

Hi,

I have Xiaomi Bedside lamp and your library after set colour is always returning "temperature 0".
If I set temp by app it returns proper light temp, at least looks like K.
Is it some different unit or why is it 0?

Can't launch on hassbian yeelightbt

Installation on hassbian with pip3 command worked, but when I try to launch the yeelightbt command I get "Command not found", any idea?

state-request works but control doesn't work

I followed exactly the steps to set up. The state request returns correct information, but the control doesn't work.

Each time I set the color, I could see that the lamp sets the color to my requested one, however it reverts it back to the original color right away. The same happened to setting temperature and setting brightness. It made the change and immediately reverted back.

I also tried turning on and off, but neither worked. Nothing happens with turning on/off.

The following is the debug output.
