Good low-voltage smart switch, except for the power consumption

Overall this smart switch works well. But a couple issues make it less than perfect.

1) The power consumption is a lot worse than advertised. On the product webpage it boasts its standby power consumption to be less than 1mW. This would have been a great feature that I was looking for. I need to use it for a battery-powered device. Since the device uses 4 Alkaline size D batteries which outputs 6V DC, I hooked SV to the same power supply. To my surprise, when the SV switch is OFF, it draws around 70mA of current from the power! This is 420mW at least. Way, way, higher than the sub-1mW claim! When the switch turns on, the total current draw shoots up to 110mA-ish. This is understandable since there is a relay coil taking the power. At this rate, the batteries won't last very long until I have to replace them.

2) A minor issue for me was that the pairing process was not smooth. I was unable to pair it using my Android phone following the official instructions. Then I searched the internet and found a discussion thread on Reddit suggesting to put the phone in Flight mode and turn on WiFi only. This did the trick. Apparently the eWeLink Android app needs some improvement.

Great for smart project where you need just close a loop

I have used 2 of them already. One to control my thermostat to act a switch when the boiler must be turned on
The other to send signal to close my gateway.

I like the fact that the input voltage is versatile and can adapt to what you have.
