I’ve been trying to get a mqtt device tracker to work which publishes a json with different attributes than the json device tracker needs such as lon and lat instead of longitude and latitude or batt instead of battery. I tried to make sense of the mqtt_json.py component file to edit it manually there but my python isn’t as great as I thought it was. I am able to make two separate sensors for parsing the lon and lat but what’s the best approach to get this to work? Make a template that puts them together again and then publish it to mqtt so that the original mqtt json device tracker works?
