I have a Kasa HS 220 Dimmer Switch that I always want to stay on at a minimum level.
It controls a Panasonic Shower LED light and I would like this light to be always be turned on (acting as a nightlight) at a minimum level (let's say 10%) when someone goes to turn the smart switch off.
I've tried basic rules, simple automation rules, room lighting and I can't seem to get the light to turn back on to a minimal level when it is turned off at the switch.
I'm wondering if this is just a bug when it comes to these particular devices. Perhaps it's not registering as actually being off? If I "activate" test rules but it doesn't work in actual settings.
It probably has to do with the fact that all Kasa devices are wifi based and don't report directly to hubitat. Even if you made a rule to run when a kasa switch "turns off", hubitat doesn't see the switch turn off in real time. It only gets an updated status based on your polling interval. You can turn the polling interval down to the minimum (5s IIRC) but this isn't ideal if you're doing it with a lot of devices. The constant polling can slow down your hub.
I don't think there's a way to disable turning a switch off within the Kasa app.
The best you can probably do is turn your polling interval all the way down in hubitat. Then just make a rule to turn the dimmmer back on to 10% any time the switch is turned off. There'll be a delay bc of the polling time but it'll work. If you can live with the switch staying off for like a minute then you can set your polling interval as such and greatly reduce how often the hub is having to poll your device.
