For those of you deep into home automation, using documentation compiled by Terrence Eden, me and Harm Otten wrote some Node-RED code to retrieve battery status from the same API that the the Renault Z.E. app uses. I’ve posted it on gitlab.
It outputs an MQTT message every 15 minutes. If there is more than one car associated with the login, more than one message is sent. A message looks like this
In my setup the message finds it’s way to a dashboard on my Android phone using MQTT dash, a Node-RED dashboard and like all other MQTT messages a MariaDb database on my Synology NAS for logging.
