I have just purchased an Echo plus and some Aqara 2-gang wall switches. I have installed all the switches and with the command "Alexa, discover my devices", Echo plus was able to detect all the switches. However the switches are detected as 1-gang only, the other button on the switch was not detected. Does Echo plus support 2-gang switches at all?
I have searched around the internet saying Smartthings hub supports creating our own device handler to make it work. Does Alexa has similar platform that I can try implement the switch handler myself?
