I’m using Home Assistant with a Sonoff Zigbee Dongle and recently had an electrician install three new Hunter ceiling fans. These fans are the Builder series and I had him install a Blue Canopy module and SmarFan switch for each fan. The setup is designed so that each fan and switch is wired independently, relying solely on Zigbee communication. Each device also has a neutral line as well.
Once the installation was complete and the power turned on, all devices connected to my Home Assistant without any issues. I made sure to set all fans to the On/Off mode instead of Exhaust mode. Before binding the switches to the canopy modules, I tested each fan and light directly through Home Assistant.
In Home Assistant, there are three controls displayed for each fan unit: Fan, Light, and Light. Here’s what I observed:
Fan Control: Toggling the Fan control turns on both the fan and the second light control, but only the actual light in the fan unit turns on.
First Light Control: This control appears to have no effect at all – toggling it does nothing.
Second Light Control: This control shows inconsistent behavior. It may turn off the light, or it could toggle both the light and fan, but the light never fully turns off. There seems to always be a dim glow, around 1%, unless I use the pull chain.
To troubleshoot, I tried binding the switch controls: I connected endpoint 1 to endpoint 2, and endpoint 2 to endpoint 3. However, this resulted in the paddle switch doing nothing, while the configuration button does control the light but seems to behave like a fan control with three brightness levels. Additionally, the light flashes once before turning on.
I’m unsure if this issue is related to wiring or if it’s a software/binding problem. Any insights would be appreciated!
Edit: I got the fans working now, but the endpoints seem to point to the wrong devices. Almost positive the wires are reversed in the module at this point.
What worked for me was endpoint 2 from the switch to enpoint 1 from the fan module, and endpoint 3 from he switch to endpoint 2 from the fan module.
On the switch, endpoint 3 is the config button and I suspect that enpoint 2 is the dimmer. On the fan module, endpoint 1 is the light, and endpoint 2 is the fan.
Hopefully, we’re talking about the same thing… and I hope this helps!
Correct, that is how I have my switches configured too. After more delving into the way the endpoints are hardwired and the way my buttons are working in HA, the only option I can find is that it’s reversed wires. Fan controls both fan and light. Light #1 controls the fan, and Light #2 controls the light. Trying to adjust the fan speed will dim the lights, but there are only 3 levels of dimming that are done, then off with a double flash of the lights. That’s all from the Canopy module, leaving the switches out of the equation. Trying to use the switch will turn the fan on and off with the paddle, and the configuration button has 4 presses to control the light: Off, Bright, Medium, Dimmish. This was after binding and unbinding and binding again to make sure the canopy endpoint 1 = switch endpoint 2, and canopy endpoint 2 = switch endpoint 3.
This sounds like you’ve got things wired wrong. Are you able to open the canopy and switch boxes and take pictures showing all of the wiring? Let’s start with one fan and work through that and then can apply that to the rest.
Hi Rohan,
No, I’m going to wait until next friday when I can have the electrician who installed it come back out and verify and rewire at need. Will the rewire be enough to resolve the issue though, or should I do a factory restore after it’s been rewired? I’ve got everything set up now to work properly (I believe) for it to be set up with correct wiring, and I’ll make sure the fan speeds are all set to high, as well as the canopy being set to high, but I’m not sure if there is anything else I should be aware of changing once we get the wiring fixed.
I don’t use ZHA, so I can’t comment exactly on how things need to be set up there, but if done the binding how @SViel suggested, you should be all set once the wiring is fixed.
Worst case if it still doesn’t work, we can work through the settings once the wiring is fixed.
Since we’re not wiring the switch to the fan at all, and relying 100% of the Zigbee bindings, wouldn’t it work more like this?
The only thing that seems wrong is the red and blue wire are reversed. IIRC they were different colors in the fan itself, so it wasn’t red-red, blue-blue. I think it was blue wire to the fan. we’ll just have to wait til next Friday to find out.
