I’ll need to write a python_script on my end to test the available options for comparing the current time to the last updated time of the sensor. I don’t have time to do that right now, so it’s going to be a bit.
Until then, if you can’t figure it out and someone else doens’t already know the answer, your best bet is to use the easyplus_on_17s binary_sensor template and include that logic in the script (as I posted above).
