Was having tones of problems getting it setup with HA. I got it setup, then within a minute the node would show dead. Exclude, try again, same thing… Factory reset, same thing… Now the switch was stuck flicerking blue fast, bulbs flicekring blue and switch is unresponsive to any commands, including factory reset.
I had wired in 1 GE addon switch so far, had not wired the second GE in yet…
In the non neutral configuration it requires a minimum b load of around 25 watts. Did you set parameter 21 to non neutral (0). You can also try lowering max dim (parameter 6) to 80%
Set the max load to around 80-85%. For smaller loads, the switch pretty much turns dead. I.e. no LEDs at all. Add more load and it will come back to life.
