Attention, in order for the product to work, I had to cut a bit of plastic on the plug because it didn't make good contact with the Sonoff and was short-circuiting. The same applies to the sensor cable

I bought 2 cables because I wanted to extend the temperature sensor of Sonoff by 10 meters. At first, the sensor was working fine for a short time as soon as you connected the cables, but then with the slightest movement, it would lose connection. I had to cut the connectors and join the cables with electrical tape. Only then did the sensor work properly. For anyone who wants to extend, I recommend getting loose cables and simply joining them. Guaranteed result.

I intended to make a 10-meter extension so that the sensor could be placed in the solar panel. I bought a total of 4 5-meter cables in order to achieve this, but unfortunately, the female jack on 3 out of the 4 cables had a problem and did not make good contact with the male jack. In the end, I just cut them and made a direct connection with insulation. I read somewhere that 1 cat5 cable will do the job properly without having to pay extra for extensions.
