How to delete an erroneous device record in Domoticz

My z-wave smart plug from Neo-cam decided to throw a single bad reading into the mix when reporting the line voltage of the TV I’m monitoring and Domoticz happily accepted it. Having a single bad device value threw out all of my long-term monitoring statistics and I could not easily remove that bad value without using DB Browser and/or another database editor on my Raspberry Pi.

Here’s the easy fix for devices that support graphing, the best part being that’s built into Domoticz!

  1. Open up Domoticz in your preferred web browser
  2. Open up the device log screen for the device in question (in my case a Utility device)
  3. With your mouse hover over the bad reading
  4. Hold down SHIFT on your keyboard and left click the bad reading
  5. A confirmation screen will appear, check the date/time and value is the bad value and hit OK

That’s it! Long-term statistics are working again. 🙂
