ESPHome Garage Door in Google Assistant

Hi,

I’ve just started using HomeAssistant, and set up a Shelly1 running ESPHome in order to open my garage door (I have a Liftmaster Pro). The garage door requires a debounce on dry contact (aka momentary switch), so I’ve configured an output button, and use a cover template to make it appear as a garage door. In HA, this works perfectly (see ESPHome config below).

I imported it into HA, and when I press “open”, it closes the relay for 200ms, then opens it, triggering the door to open.

I also have the Google Assistant integration, where the device appears when sync’ed (as do my other devices), but the GA garage door is working like as if I’m handling the underlying relay, requiring two actions to work (If I open, then close the garage door in GA, after the second action it works), instead of working the same way the HA cover works.

Is there something I can do to get the GA garage door to behave properly? I know the underlying GA protocol, and I’m reading the code in traits.py, but it’s not clear to me why the cover behavior isn’t taking effect via GA.

I actually figured this out after reading through enough of the code to debug (via the template in develop tools for inspecting state, and via the services tab).

It turns out that Google Assistant doesn’t require a pin for door close, and since I have a simple push-button opener, Open was failing, but Close was succeeding, and therefore opening the door.

I had added a pin to my configuration, but forgot to save before closing and restarting, so the open command was failing every time.

Once I re-added the pin, saved and restarted, the garage door started working as expected.

Hi there.

Where did you put in the pin code? I have the same setup woth esphome. But i cant figure out where i put a pin code to make the door work with google Voice command.
