@JDRoberts All C2C devices are identified as placeholders in the IDE, that’s normal and it should not be changed manually as it’ll cause unpredictable issues.
However, C2C devices do report their supported capabilities as part of the WWST integrations and those capabilities are reflected in SmartApps.
We’ve made some updates to our apps like LUM to support these newer capabilities from the new platform which are coming in via C2C integrations so it should work with Meross as well to control garage doors. However for this specific use case, most apps are looking for a contact sensor capability which Meross may not support, but with a little update to the Door chimes and notifications app we should be able to get Meross garage door opener to work with that app to notify you.
@nateio if you have access to RBoy Apps feel free to send out support desk and email and we can get you into the BETA program to see if that works for you.
EDIT: The Garage door manager smartapp is already updated and should work with the meross garage door controller C2C capabilities.
