rtlamr2mqtt VS WOL-proxy

Using this project to get my Gas meter reading into Home Assistant (and indirectly into InfluxDB)

If you have a meter that reports gas usage via wireless you can use a software defined radio to pull in all the data using rtlamr2mqtt addon https://github.com/allangood/rtlamr2mqtt

I used https://github.com/allangood/rtlamr2mqtt to actually read the data off the wire and put it into MQTT. Homeassistant then reads from MQTT.

This is correct. As someone who currently monitors my meter in real-time using rtlamr2mqtt, I can vouch for the benefits of knowing your energy usage in real-time. I had a rooftop solar array installed recently, and I use real-time monitoring to see whether I’m generating excess energy, which helps me know when the best time is to run my clothes dryer or charge my car. It absolutely helps people make better choices around their energy usage, and I think it’s something everyone would benefit from if it was more easily accessible.

My first use case is energy monitoring, pulling in electric meter readings using rtlamr2mqtt, which I already have going with Mosquitto. I also have my OpenEVSE publishing MQTT, and tried out HA's SolarEdge API integration. It sounds like OpenHAB's MQTT integration should be easy, but I'm uncertain how I'll see the data.

Absolutely! I'm using a Nooelec NESDR Mini as a Software Defined Radio connected to a raspberry pi that's running a program called RTLAMR, which will pickup all the Automated Meter Reader signals in the area. There's some research you'll have to do to find your meter ID, manufacturer, and protocol, but once you have it narrowed down to your meter you can publish the entries to an MQTT instance using rtlamr2mqtt, where Home Assistant can pick it up and use it to track your total energy consumption.

I've heard that this works well with the meter NS Power uses: https://github.com/allangood/rtlamr2mqtt

Tell each users to run a special program to wake up the server (only works inside the local network) or run a small server that receives the special wakup call like: https://github.com/seanauff/WOL-proxy something like that could even be done with a microcontroller like the esp32.
