I just got my VZM36 Smart Fan/Light Canopy Module (Fan Speed + Light Dimming) and am trying to both:
- Connect the canopy to Home Assistant (HA)
- Use my existing LZW36 to control the canopy (LZW36 has the known issue)
So far I’ve been able to add the VZM36 to HA without any issue. But by default I have 2 light controls and 1 fan control. I quickly discovered that one of the light controls manages the fan.
Using HA, the light and fan controls do not operate consistently.
- There’s a 2-4s delay in actions
- Occasionally, the light flickers in a pattern of 3, pause, then 3, then it either turns on or off.
- Sometimes the HA controls don’t work at all and the icons are not representing the states (ie: light is on, but the light icon is off)
Also, I can’t seem to find the spot to see and change parameters. I’m more familiar with ZWave, but if anyone has a tip on where to find it in HA let me know.
Anyway, I did create a simply automation based on this blueprint I use for other switches to:
- Top button press: Toggle light
- Bottom button press: Toggle fan
- Top button top rocker: Increase brightness
- Top button bottom rocker: decrease brightness
The issues I’m having are:
- I don’t see an option to increase/decrease fan speed. Is this available?
- The button presses are extremely inconsistent, only working less that 20% of the time for any action.
- It would be great to connect the LZW36 LED notification to the states and speed/brightness, but that might be a more complex automation need.
Below are my recent log entries, with several 102 errors.
Is anyone else experiencing these issues that can help? Or is there a special set-up needed for HA and the canopy?
Quick update: it is now showing that the canopy is offline
