Dirty solution to have both fast and slow speed available for Switchbot Curtain 3

This solution requires you to replace /homeassistant/deps/lib/python3.12/site-packages/switchbot/devices/curtain.py with the modified file. If you need the original one back, you can get it from the original repository.

I used the file /config/custom_components/.slow as a binary identification between the modes. You can modify the path in the file curtain.py by changing the global variable FILE_SPEED_IDENTIFIER.

This is a pretty dirty and hacky solution but it is working fine for me and since I am not into integration development I was not able to develop a better solution quickly.

Steps to apply this to your installation

1. Replace the curtain.py file inside the docker container: docker cp /homeassistant/curtain.py homeassistant:/usr/local/lib/python3.12/site-packages/switchbot/devices/curtain.py

   Alternatively, you can add the pyswitchbot-repo using Custom deps deployment and replace the curtain.py file there. The path is:

   • before HA 2024.2: /homeassistant/deps/lib/python3.11/site-packages/switchbot/devices/curtain.py
   • after HA 2024.2: /homeassistant/deps/lib/python3.12/site-packages/switchbot/devices/curtain.py

   If it was installed with python3.11 you can just rename the folder to python3.12

2. Adjust configuration.yaml and add the directory where the identifier .slow file should be saved to the allowlist_external_dirs

   allowlist_external_dirs:
       - "/config/custom_components"
   

3. Create directory /config/custom_components and file .slow inside

4. Write 0 or 1 into the file

5. Add shell_command to enable or disable slow mode for the curtains

   switchbot_curtain_enable_slow: 'echo "1" > /config/custom_components/.slow'
   switchbot_curtain_disable_slow: 'echo "0" > /config/custom_components/.slow'
   

6. Reboot Home Assistant

7. Have fun and use it by calling either one of the services before calling the cover-services:

   shell_command.switchbot_curtain_enable_slow
   shell_command.switchbot_curtain_disable_slow
   

What does this modification do?

Basically, this modification only checks if 0 or 1 is in the file .slow and use this as binary identification to either go slow or fast. The following excerpt shows the file read:

with open(FILE_SPEED_IDENTIFIER, "r") as fr:
    r = int(fr.read().strip())
    if r == 1:
        self.slow = 1
    else:
        self.slow = 255

If you for example call the cover.open_cover service, the speed will be set before sending the command to the switchbot:

speed = self.readState()
