I have several motion sensors that I’ve set up using my Sonoff Bridge with the following config: - platform: mqtt state_topic: "tele/sonoff/RESULT" name: "Office Motion" value_template: "{{value_json.RfReceived.Data}}" payload_on: "E63B42" payload_off: "E63B42off" device_c…

Another copy-paste problem. I don’t know where this code originated, but it’s never going to work in the form you’ve posted it — the binary_sensor is expecting to receive structured JSON but your automation is sending it a simple string. Solution in my post in this topic: [image] E…

I changed the code to reflect your suggestions but it made no difference. I even commented out the references to the element that shows up in the log in both automations.yaml and binary_sensors.yaml, but the error still appears in the log. Error parsing value: 'value_json' is undefined (value: E63B…

You need to restart HA for the changes to take effect. The error message is quite clear: your sensor template is expecting a different structure to what your automation is feeding it.

I restart it after every change I make. I’ve even hard rebooted the NUC to be absolutely sure. Any reference to E63B42off is commented out in automations.yaml and binary_sensors.yaml, and yet the error still appears. Are these the only two places the template could be in?

Well, if you’ve restarted and haven’t (to your knowledge) used the templates anywhere else, the error should not be occurring still; and your code looks good to run as expected if uncommented. Are you sure these aren’t old errors?
