Bad Reception

This is a USB Boarduino with an 868 MHz receiver connected to it:

The antenna is a short 82 mm wire. Just like the one used in this setup. Given the same software, it receives the same signals.

But somehow, it’s considerably less sensitive – so far this unit won’t pick up the (faint) transmissions from the energy monitor nearly as reliably as the first setup. It’s not a matter of noise signals, antenna placement, or any hardware differences (all physical variations give the same result). Must be moon phases, or something. I’m going to let it rest and focus on other RF options instead.

The original polling setup has been working fine for several days now, btw.
