In-service for 3 months now without issue – Household 50G Water Heater
Let me start with — The effort was worth it $$.The easy part… Adding this device to the power feed at the water heater. My electrician friend had it installed in about 10 min.The interesting not so easy part — Connection to the network and programming.- I struggled to connect to the network – This only connects to 2.4G, and I could not find it on my network.- I created a 2.4G and 5G mode and was able to find it and connected.- Programming took me a bit of time, but not too bad. I now have a weekday and weekend schedule and easily turn off the “On” part of the schedule to leave it off while on trips. Turn the schedule back on before I get home, remotely! :-)I have not had one issue with this smart switch since I got it running. My biggest upfront issue was the 2.4G connection. If you already have a visible 2.4G/5G network, your setup will be easier. You need to have a 2.4G Wi-Fi signal where this switch will be installed.

nice product
This is an awesome little switch, it was exactly what i wanted and needed, this thing works like a charm, once you figure out that it really is a double pole switch that is 240volts, 120 volts on each leg, your good to go. see the problem is that they label the contacts L and N which in the real world is line voltage and neutral, it should be labeled L1 and L2 because both the load terminals make or break with this switch, so it is very suitable for breaking both legs of 240volt circuit. what gave me the hint was the little motor symbols on each terminal. their description isn’t as clear as it could be. you can also use this for 120volts, in which the neutral leg would also break, it hooked up easily to my router, but needs to be guided to the 2.4 gz of a daul or tri band router, once that is done, awesome switch.

Overheating (fire danger)
This product is dangerously underbuilt. The internal electrical wiring is too small for the load it claims to handle. Even when used under normal, advertised conditions, it quickly overheats. After a short time, it stopped working completely.This is not just poor design — it’s potentially a fire hazard. If you’re looking for something safe and reliable, I strongly recommend avoiding this product.

Great for automating landscape lighting
We had an old mechanical clock driven switch for the landscape lights. As days get shorter or longer it was a hassle having to manually go and change the little screws. I removed the clocks snd installed this instead. Now the landscape lights are controlled by Alexa and turn on 20 minutes before sunset, whenever that is and off at midnight. Note that in USA for tis to be code, it will need to br installed inside a box. The box needs to br plastic, otherwise wifi will not connect.

Compact and easy setup.
Very compact, fits inside a 2-gang outlet box with enough rooms for the incoming and outgoing circuits. Also easy to set up. The only thing to watch out for is the terminals are very tightly positioned. Need to use crimped spade terminals as terminal design not suitable for direct termination of #10 AWG wires.

Funciona de maravilla para poder controlar cualquier aparato electrónico desde una lámpara que quieras automatizar para encendido/apagado hasta una bomba para agua, sólo funciona con conexión WiFi a 2.4 Ghz

Dangerous. I should have taken note of the poor reviews – definitely did not handle anything close to 30amps. Burnt out after a few minutes use, this could have been a real concern if I had not been in the right place at the right time.
