Trigger failing

Configuration
1

I’m sure this must be the most common topic but here goes.
I’ve just created a automation to switch on/off a towel rail heater using a Shelly plus1 relay, this dependent on the percentage charge of my Tesla powerwall battery.
I have created two threshold sensors that are in an on or off state, one when the battery is above 99% and one when the battery is below 97%. I can see these are working correctly changing from on/off and visa versa. I have used these in two automations one to switch on the towel rail and one to switch it off.
I have checked the states that should cause the trigger are working, I’ve checked the action is working correctly manually but for some reason the automation will not trigger. This is the automation that should turn the towelrail on when the battery is above 99% (the threashold sensor will then go from off to on), can anyone see an issue?

That’s your problem

The trigger is waiting for that attribute to go from off to on.

That’s never going to happen

Remove that line

I don’t understand the state of the sensor does change from off to on…

Thanks that worked.

Yes, the state changes, and you configured the trigger to look not at the state, but at the attribute sensor_value.
