Re: Opentherm Gateway disturbing 433 Mhz signal reception?

Sorry for the long delay, but I wanted to be sure it is working now.
I have rechecked all the connections and now the gateway is running as I think it should. No more Error 03's or connection issues.

Re: Opentherm Gateway disturbing 433 Mhz signal reception?

Thanks for your answers. I agree it sounds unlikely but testing is very very convincing, as soon as I unplug the power from the OTGW signal reception increased dramatically. And this is without the USB connected. Vincent, thanks for your suggestions. I have tried with Aluminium wrapped around the bo...

Hello, I have been testing the OTGW for the past weeks and I have noticed it seems to jam my reception of 433 Mhz signals. I have both the OTGW (via USB) and 433 (via arduino nano/USB/pimatic) on the same Raspberry Pi 2. They are physically about 2 m separated. What I have noticed is that after the ...
