I’ve been working on an integration to pull data from the Swift Command remote access webpage/app.
It allows you to show the location of your caravan on a map along with status information such as battery voltage and temperature (Although I haven’t worked out the format of the temp yet, I took a stab at it being in fahrenheit but I’m not too sure it is so will have to confirm next time I have the caravan at home.
I’ve used the map entity and attribute entity cards to display in a panel.
