Angile

Since I can't find a SonOff water detector and I need a WiFi water alarm, I made one by modifying a Geervon 9 volts Water Detector, a SonOff DW2 WiFi and a AMS1117-3.3DC regulator so replace the 2 x AAA batteries. Now it all work on one 9v battery, placed on top of the device because I need it interior space to place the DW2 and voltage regulator.

Is there SonOff weather station available?

Is there SonOff water detectors available somewhere?

I needed a temperature control 12 volts switch. So I modified my TH16 circuit board as follow: Using a Dremel, I cutted the circuit on both sides (IMPORTANT) between the relay and resistor and soldered a jumper 14 ga between the ground terminal (not in use) and the relay . The result is a Normaly Open contact to control my 12 volts circuit. One of the 2 N/O contacts should have been identified as C for Commun. 😊 Do this at your hown risk!

I have to replace my refregerator's control, but it is back ordered for + 1 month. So I installed temporarely a SonOff TH16 with an AM2301 sensor in place. So far, so good. I setup the temperature to >2 and <7. Compressor is ON for 10 min and off 20 min avarage.
