September 30, 20223 yr Hi All, hope I can get some advice. my DB is awkwardly placed behind my fridge and my geyser breaker in down the side of my house. I have i stalled a changeover in the garage which is separate from the house for my 7.5 Iva geni (whose all this load shedding it’s pretty expensive to run) im looking to instal a small 3kva inverter in the garage on my auto changeover however I need to turn off high consumption appliances I have found the Sonoff loadshedder and wonder I I get the geyser switch if I can automate the geyser to turn off whenever there is a power outage and prehaps do the same for some plug points/ stove etc… any advice?
October 1, 20223 yr If loadshedder acts similar to the DIY solutions for detecting loadshedding it'll act like a "door" switch,ie Open and Closed statuses You can set Ewelink to turn a circuit/device off based on this status. It won't be instant at worst if you use the default firmware and app but it should cut within a few minutes

That is what I'm doing sonoff on inverter side with relay to mains for a trigger when mains go off,then just run you custom scene,in my case loadshedding fish tank heater,washing machine and extra outside lights off. Will add more as I get more smart switches

Are you planning on running any form of home-automation? if so there are many ways to detect the power outage and this device is overpriced. The EWElink app has a automation function but I believe you pay extra montly subsription if you want to integrate with IFTTT. Get a https://leroymerlin.co.za/smart-controller-astute-cbi-81457725 and manually switch them off on the app when running on the small inverter.

A simple way would be to disconnect the high loads via 3 contacts in parallel. Maximum load of 30A. The small Sonoff only controls the coil which uses little power. Sonoff is used to give a push msg on phone to indicate grid is off.
