That behavior is not limited to Lutron Caseta and implies Home Assistant can successfully send data to the device (it can turn the light on) but fails to receive data from the device (it’s unaware of any manual changes you make to the device’s state).
The other telltale sign is when you use Home Assistant to turn something on and, a moment later, you watch the toggle switch automatically set itself back to the off position. That’s because:
- Home Assistant sends the
oncommand - didn’t receive a reply from the device (a status update) reporting that it is in fact
onnow - so it sets the toggle switch back to
off
Your task now is to figure out why Home Assistant is not receiving status updates from Caseta.
