I use that at home (which also gives me Alexa integration) and used the Remote Assistant plugin for the one at the cottage. For now, I connected that Home Assistant to its own trial version of Nabu Casa until I get another way of connecting both together. It doesn’t solve my security camera and weather station remote access though, especially through my watch (for the weather station).
Yeah, I didn’t want to push it further with them so I tried on my own and had some success but it was flaky, so I dropped that idea.
