I have integrated my two Juicebox EVSEs into Sense.
Sense <-> Senselink <-> Home Assistant (with JuiceNet addon) <-> JuiceNet API
I get 30 second resolution and surprisingly was able to get home assistant docker up and running within 5 minutes (I’ve never used home-assistant before). Adding in JuiceNet integration was one minute or less and getting my API code was more time consuming.
Granted, I had earlier spent an hour or so learning Docker and getting SenseLink working but I figured Home Assistant was going to be the bigger hassle but thankfully not.
