It’s probably not something that many people think of doing, but recently we had the air pressure switch on our sink break, and quite honestly, the price of a new switch was ridiculous.
Sooo… I just threw a SonOFF basic under the sink and wired it to the disposal, created a NodeRED flow to manage powering the unit off, and now we just ask Google to turn on the garbage disposal.
10 Seconds of run time and it shuts off. There is a slight risk to the setup as a malfunction would be bad while reaching into the drain…so we don’t reach into the drain unless we unplug it. It’s rare that we would need to do that.
So far, so good. Although, I’m not really a fan of being a slave to a cloud based control device like Google…but we can work on that down the road.
