Tag Archives: emoncms
Now I’m getting somewhere!
As I posted yesterday, the kwh_accumulator process in emoncms requires Redis to be available. Fortunately there’s a Docker image for that and it was just a case of pulling the image and starting it. I came up with a systemd … Continue reading
Never mind steps forwards and backwards…
Over the last couple of evenings I think I’ve been all around the houses 🙁 I pushed my new device templates into emoncms, but they just wouldn’t work properly. The various processes didn’t get set up and I kept getting … Continue reading
Second take on emoncms device template for RFXmeter
I felt I needed to revisit the template for my RFXmeter devices because what’s really required is kWh consumption figures between readings rather than cumulative values. Also there needs to be a way to handle the count values rolling over. … Continue reading
Two steps forward, one step back

Publishing RFXmeter power sensor data to MQTT
More hunting around for helpful modules led me to believe that the easiest way to get data from my RFXmeter sensors into MQTT/mosquitto so it can be read by emoncms was to stick with Perl and use the Device::RFXCOM and … Continue reading
Adding support for new devices to emoncms
To be clear: I’m not certain this is the right way to go about this. It’s mostly based on guesswork and assumption from what I’ve scraped together reading around the discussions about emoncms. For the moment it appears to be … Continue reading
Setting up emoncms in Docker
As I posted earlier, there’s a github project for setting up emoncms in Docker, but the configuration assumes that a MySQL instance will be set up in a second Docker image and everything built together with docker-compose, which wasn’t what … Continue reading
