Two steps forward, one step back

Posted on December 21, 2021 by james

This evening I made rather better progress with emoncms than I did a couple of days ago. I decided to go all-in and set up supervisord to control the processes running in the Docker container and that seemed to work … Continue reading →

Swimming, 20th December 2021

Posted on December 20, 2021 by james

I didn’t get to swim on Sunday which was a disappointment. Apparently Everyone Active’s booking system “lost” the session details so they couldn’t be booked. They’d have let me in to swim if I’d turned up though. Shame the receptionist … Continue reading →

Why do Hermes still exist?

Posted on December 20, 2021 by james

The world being the way it is, we’ve probably had more deliveries than usual this winter. Quite a number of them have, sadly, been misdelivered by Hermes. Some have merely been several days late on a “next day” or “48 … Continue reading →

One step forward, two steps back

Posted on December 17, 2021 by james

I’ve spent a happy (hah!) evening trying to work out why emoncms wasn’t recording any data from MQTT. The documentation seems to claim it “just works”, but I just couldn’t see anything happening, even when I’d checked that the code … Continue reading →

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 →

Swimming, 16th December 2021

Posted on December 16, 2021 by james

My shoulders felt very tired whilst I was warming up today so I wasn’t expecting to achieve much, but actually it didn’t turn out too badly in the end. I did fail two of my 50m reps, but the first … Continue reading →

Adding support for new devices to emoncms

Posted on December 16, 2021 by james

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

Posted on December 15, 2021 by james

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 →

Swimming, 15th December 2021

Posted on December 15, 2021 by james

Having taken Monday off because I didn’t feel great I went back to the pool today not really knowing what to expect. As it turned out, my 50m reps weren’t that bad and I only failed one, though I did … Continue reading →

The power monitoring plan is coming together

Posted on December 14, 2021 by james

As I may want to use power consumption data (and other information, such as data from the weather station) in a number of different applications, I’ve come to the conclusion that MQTT may be a way forward, allowing those applications … Continue reading →
