The 3asmarthome 3 gang switch is a HUI Feibit 3 gang switch.
3asmarthome is going to send me a dimmer to try but I dont have it yet.
I have fixed my bodgy Device Handler for this switch that is based off Smartthings Switch Template and Andy’s KUDLED 3 gang switch. After the September 19 App update my original modded Device Handler turned my lights into Christmas Tree lights :o(
Anyway, changed a few things and all seems to be fine again - can’t guarantee what happens if the Smartthings App is updated again. Maybe OK if it is a December update as you might get free flashing Christmas lights ;o)
I found that the switch works better with 3 complete simulated switches. Anyway, for me it updates in the phone app and IDE if you use Alexa or GH or the actual switch itself to turn the switches on or off. Don’t really quickly turn them from off to on and back off again though as it needs time to process each on and off so everything updates. Don’t blame me if your house burns down or a black van turns up out side your place as my hack code is pretty dodgy…
You need both the Device Handler and SmartApp together to get this 3 gang switch to go.
GC it would help if you could provide the end point IDs for the 1 and 2 gang switches to edit for the DH and SmartApp as I only have a 3 gang switch atm. I am assuming the End Point IDs are 12.
