[Request] Tuya power outlet support #97

Can you add links to these devices? (Even better - links to an API for them?)

bsaurusrex commented 1 year ago

The devices are all generic but run under tuya cloud. There is a lot of information available for home assistant addons like "localtuya" or using the traditional tuya cloud API.

I’m not likely to end up supporting the cloud, but if there is a (user friendly) way to support the devices locally I might be open. Is there any API documentation out there for local device support?

The critical feature is some way for the switch to shut off if it doesn’t receive a command in a certain period of time instructing it to stay on.

Localtuya is an option. https://github.com/rospogrigio/localtuya

I picked up a Kasa outlet.

Sounds good. I’m still open to adding support for other devices, but the two crucial features I’d like to have in a device are a “dead man’s switch” and local connectivity.

For Kasa switches there is a feature that lets the BrewPi-ESP tell the switch every second, “Hey, stay on for 5 more seconds”. If the BrewPi then crashes (or the router goes down) then you don’t have the risk of your heater/cooler staying on forever and boiling/freezing your beer as it will automatically shut off once that timer is reached.

Kasa switches also happen to have a local, non-cloud protocol which means that if your internet connection fails for any reason (but your router stays alive), your beer will continue to be controlled.
