Once I find the device I'm looking for, how to filter out all others by ID?

[jbishop129]

I'm sure I've seen this described in the docs, but for the life of me I'm failing my search terms and cannot find it: Let's say I've enabled the correct protocol decoder for various known utility meters at my home. I let rtl_433 do its' thing, and after I have a positive ID on my utility meter, I want to filter that protocol to only bother decoding and sending to MQTT, a particular device ID. I don't want to collect dozens of neighbors' utility meters, just mine.
I could swear I saw described where you can do some form of filter={deviceID} of sorts, to ignore everything except what you're looking to watch. Any pointers from the community here? Thanks!

No, sorry, such a filter is only available for custom flex decoders.
But there is a filter script (MQTT to MQTT) to run such actions https://github.com/merbanan/rtl_433/blob/master/examples/mqtt_filter.py
Or you can build a bridge (UDP to MQTT) https://github.com/merbanan/rtl_433/blob/master/examples/rtl_433_mqtt_relay.py
