We had an Accurite rain gauge - wifi but not smart phone connected - til it died recently. And then our ancient sprinkler system controller died. Replaced controller with a smart one. One problem, as mentioned earlier, is it relies on rain forecast, rather than actual rain. Installed free RainDrop app on phone, and it gives rain measurement at a specific location, ie our house. We've had only .26 in the last 48 hours, as opposed to several inches nearby! Sprinkler controller wants to stop sprinkling due to the surrounding forecast. We'll keep the app.
