Missing action for Matter RVC to return to dock (Go Home)

Devices & Integrations

Came across a post in reddit complaining about the lack of a way to send their Matter vacuum robot to the dock using SmartThings. I investigated a bit to see if that was a Matter feature (it is), if Tapo implemented it (apparently so) and if SmartThings exposed it (no).

Looks like that’s a command called GoHome that the RVC drivers don’t call (and in their included definitions for old hubs is not even present), maybe because they were created back when in Matter 1.2 the command did not exist. The command was introduced as provisional in Matter 1.3 and since Matter 1.4 is no longer provisional (but still optional).

Guess it would be nice to add support for that action in the capabilities and the stock driver for devices that support it. Tagging @Itati

Anyway, writing the post as reminder if I ever get a Matter vacuum or if someone misses the action and wants to add it to their custom drivers while SmartThings implement the feature in their own.

A mandatory requirement for Matter 1.5 certification should be feature completeness to any previous version.

Seems like Matter features are only added when needed for a WWST certification.

We’re starting to develop our own Matter drivers to get support for basic features!

Cool! Thanks for the pointer, I like how they are approaching the implementation of new features in a dynamic way, detecting if the command is supported or not to enable it in the capability and presentation - that they’ve also had to modify to add the new commands like goHome.

That, the modular profiles and the default (and native) handlers are going to be a true game changer for the whole Matter support in SmartThings.
