I am in New Zealand but can import from either US or UK. I have seen the Fortrezz one but was hoping for something that I could simply screw onto the tap, much like a basic timer.
New Zealand is a problem as they have their own Z wave frequency. It is illegal to use either the UK or the US zwave frequency there, as they can interfere with first responder communications. So that leaves you with zigbee ZHA or Wi-Fi options.
Hi, I have used a Sonoff running tasmota and a 230V valve
I have then written a smartApp switching the valve on every day for a set time. I reaslised that it was watering in the rain which doesnât make any sence so I have used the WeatherChannel to only water if it is hot and dry. I have set the tasmota software on the sonoff to switch off after 30m of running so if I have an internet failure it wonât flood the street!
It works a treat and cost me under 30EUR in total.
I have ordered a basic 230V AC NC valve that i plan to connect to a smart plug, so similar setup. I will have a look at your sprinkler app as i am on the look out for one. Good idea to put a timer on the switch as a back up, i will probably do the same!
