It heats water on a timer whether you're going to use it or not, and it carries on doing that all year.
These two controllers fix that, and they're managed from one app on your phone.
HotBot
by Plentify · R849 once off · R149 a month
HotBot learns when your household actually uses hot water and heats the geyser to suit, instead of running to a fixed schedule. It also picks up a leak early, which is the difference between a plumber and a new ceiling.
It works with electric and solar geysers. A home with two geysers needs one for each.
SolarBot
by Plentify · R849 once off · R149 a month
If you already have solar, SolarBot decides when to charge and when to draw on the battery, leans on your own power rather than the grid wherever it can, and can heat your water off your solar instead of buying electricity to do it.
Since a unit you use yourself is worth considerably more than one you sell back, anything that shifts more of your usage onto your own power is working on the right problem.
