I found were it says about the Homekit “MyQ Home Bridge adds smartphone control to your MyQ enabled garage door openers (without built in Wi‐Fi)”. But your combalabity site says it recommends the Homekit even on openers with WiFi built in. If you want voice control. Which one is it?
It’s both, the myQ bridge is required for openers without Wi-Fi (including 3rd party) and the HomeKit bridge ( a different device) is required to get HomeKit working with Siri and the home app for iPhones. The HomeKit bridge will pair with the myQ bridge or myQ openers with wifi
If you opt not to add the HomeKit bridge but use the myQ bridge then you can still use your phone to open and close the door but will require opening the myQ app to do so (no Siri support)
