WiFi Sprinkler Timer with Brass Inlet, Smart Solar WiFi Water Timer for Garden Hose No Need Hub, Rain Delay/Auto/Manual Override, Alexa/Google Assistant Compatible, APP Remote Control via 2.4Ghz WiFi

I bought this one for last summer after my previous device was eating through AAs. Zero issues with this. The solar panel makes it a set it and forget it. Connects and works well with the Smartlife app that my other wifi devices are on. Sticks the watering schedule I set and I don't think about it.
