I am currently using a Raspberry PI + an RTL_SDR dongle (hardware) together with rtl_tcp and rtlamr (software) to capture the meter reading data broadcast by my utility meters (electric, gas, water) on the ~912 MHz band.
I then use my modded version of amr2mqtt to post the data in MQTT form to my Mosquitto Broker which then gets inserted into Home Assistant.
While the solution works well, it would be even nicer to run it on say one of the LilyGo LoRa 915MHz esp32 boards. That would give me a standalone embedded IoT device approach…
Unfortunately, rtlamr is written in Go so I have no idea how it might be ported to OpenMQTTGateway – but I was wondering if anybody has worked on alternative solutions.
