Help with RTL_433 using 2 USB Dongles for 433 and 915mhz

Configuration
1

Im trying to listen to 433mhz for door sensors and 915mhz for my water meter, but i’m getting stuck on how to configure this.

I’m trying to setup 2 USB RTL dongles in HA, I have the 2 deferent dongles serials changed to different numbers. Now where and what do I put to get this to work? I see the RTL_433.conf is that where I put the config? and what do I put there?

Do you have MQTT set up?
You can use 1 dongle to do both bands. Here’s my conf:

ppm_error 18
output json
output mqtt://hassio-vm.mydomain.com,user=mqttuser,pass=pass,retain=0,events=rtl_433[/model][/id]
report_meta time:utc
hop_interval 60
frequency 915M
frequency 433.92M
frequency 915M
frequency 915M

Ya I have mqtt setup, but my 433 stuff is door sensors so I want to make sure that is always on.

Makes sense. In that case, I think you can run 2 instances of RTL_433 Have the MQTT settings in the conf file, and specify the frequency and ppm correction (if needed) on the command line.

I had two dongles running for a while. I was using the RTL_433 add-on. To get it to work, I had to fork the add-on and install both the original and the fork. Then you can configure each one to use a different .conf file.
