Weather station comes with outdoor wireless sensor that itself also has a LCD.

3-channels, multiple stations can receive data from multiple sensors. Not very strong signal, I am not receiving signal from detached garage about 30ft from the house, but I am getting signal from the porch outside. I guess that is a good thing, so neighbors wont be interfering.

I have 3 units and they are within 0.2’C and 2% RH from each other – at room temp. At -20 situation may be different.

Both devices powered by 2x AA.

UPDATE:

If anyone is interested whats inside, I am adding these pics. I have cleaned the humidity sensor and it got dramatically closer to what it should be, must have had thin layer of dust on it.
