The second edition of the Rachio Smart Sprinkler Controller has made my life a whole lot easier. Out yard sees a lot of sunlight so watering it at the perfect time is ideal if we want to keep it green all year around. Thanks for recommending these, I agree – I think Rachio is the best.
Do any (or all) of these devices enable me to limit the watering to specific day(s) of the week, in order to follow local HOA requirements?
yes they most all do
Blossom does, not sure of the the other ones. The Blossom App, let you turn off completely any day of the month with a single tap.
I have a standalone wireless network that is not connected to the Internet
I am looking for a web based wireless sprinkler controller that can function without connecting to the Internet.
Are you aware of models that will operate without Internet access?
Thanks for your reccomendations! Last week I came to your site and read about the Rachio and ordered it. I just installed it yesterday and the thing is amazing! Works exactly as I need and we LOVE the smartphone integration.
is it possible to control 9 zones irrigation valves with a 8 zone controller. I am thinking to combine wires for 2 zones which requires lesser water pressure ? Are there any other alternatives
I would caution against wiring 2valves on one zone. Most controllers cannot supply the increased current requirement of the two valve solenoids and you risk damaging the electronics.
Check the installation instructions of your unit.
Would be better to connect the piping of the two low flow zones rather than wire two valves on one zone.
I have a b-hyve system. Loved it at first. But, the app on my phone and IPad don’t indicate which zone is running. It worked great for awhile, but now having problems. The box itself is correct on which zone is running. Have sent numerous emails and tried calling multiple times with no response. Very unhappy with customer service. Any suggestions? Thanks
Thank you for the information? Are there any controllers that also interface with water PSI/GPM sensors?
