Tried in the UK on an Elster AS300P electricity meter

[nitropaul]

I have installed the 'rtlamr2mqtt' addon into HomeAssistant, i have connected my SDR device and tried scanning for my electricity / gas meter but I dont see anything. I know they are not in the supported devices but i thought I would give it a go. My config is standard as it was installed and my log file is as below. Does it look like it is scanning properly? Is it probably just that my meter uses a different protocol?

If I set listen_only to 'true' i get the following log:

Both of those logs look normal for rtlamr, but probably there are no supported meters in range.
