Does anyone know of a reasonably priced garden water valve that is zigbee and solar powered, that pairs/works nicely with HA?
I’m sure there’s better solutions, but you could have a look at IKEA’s “Knycklan”.
It’s powered by 5V through micro-USB, so you should be able to run it from whatever solar powered inverter/power bank/car battery system you want.
Struggling to find a link for you, but I only find product pages in Swedish.
It’s intended useage is to turn on/off water for a dishwasher.
