Timers

[Zigis]

I’ve tried multiple times and just keep failing at this timer setting. Can any one help ?
I’m trying to set a timer to run for 1 minute every 3 hours to stir a kalk reactor.

I use these WiFi plugs. They are great. You can set up timers as well as control them from your phone.

Wifi plugs look neat. I've just used simple digital "lamp timers".
