Missing the beat?

Controlling things on 433mhz is cool however I also need to be able to rely on the signals to arrive.

I have been experiencing missing sensor values from one of the temperature/humidity sensors (located in the kitchen). I get readings, but I think I miss more of them. I tried to move around the RFXCom a bit but so far this hasn’t improved connectivity.

Since I have my pumps also in the loop I also saw that the ‘off’ signal doesn’t reach the switch once in a while. The distance between RFXCom and this switch is very low (5 meters).

At the moment the RFXCom and a USB wifi adapter are directly connected the USB ports of the raspberry pi. I think the next thing I will try is to get an active USB hub, and see if that improves the situation.
