Hi everyone, I wanted to share my experience with smart meter data collection and how I managed to overcome some challenges. If you’re using devices like the EDL21 or Shelly EM3, you might find this useful!
My Experience with the EDL21
I’ve been using the EDL21 smart meter with a Hichi IR reader connected to my Raspberry Pi. It’s been working flawlessly for days, but every now and then, it stops sending data. This is a bit frustrating because my home automation relies heavily on energy consumption data. After some research, I found that I’m not alone in this issue. A quick search led me to this GitHub issue, which confirmed that others are experiencing the same problem.
To solve this, I decided to monitor the entity Smart Meter Summe der aktiven Momentanleistung. If there are no value changes detected within the last 10 minutes, I trigger a Home Assistant restart. This seems to be a reliable workaround for now!
Shelly EM3 Firmware Update Issue
Another interesting case I came across was with the Shelly EM3. A user reported that after a firmware update, their device stopped showing any values, even after reverting to older firmware versions. This is a common issue that highlights the importance of regular backups and testing before updating firmware.
Lessons Learned
- Always monitor your smart meter data regularly.
- Keep backups of your firmware and configurations.
- If you encounter issues, check community forums and GitHub for existing solutions.
It’s incredible how the community comes together to solve these issues. If anyone else has tips or experiences to share, I’d love to hear them!
Cheers,
