I’ve been noticing on and off that the utility meter does some pretty weird things, sometimes recording energy I can’t account for, but today I’ve caught it doing a full value reset, not to 0, but to the end value of the previous day.
Here is a picture showing what happened.
As you can see, at midnight the meter resets to 0, but then 6 minutes later it updates itself to the value the previous day ended at.
And it didn’t do it to just one meter, it did it to both my peak and off peak meters…as you’ll see here.
Here is the sensor the utility meter is fed from…
It might be hard to tell, but there was next to nothing happening as I was still running off my home batteries at the time.
And just for completeness, here’s the very simple config driving the meter from the sensor shown.
grid_utility_meter:
source: sensor.pwc_solax_local_grid_import_energy
name: Grid Utility Meter
cycle: daily
tariffs:
- peak
- offpeak
I only picked it up because I noticed the aabnormal values on my energy screen as below.
The grey showed un accounted for energy, the red was my heat pump water (which was running off batteries) and the green was my heat pump heating meter, the only real value that should have been on there was the red hot water, but even that had a bump at the same time as well.
So looking at the water meters, it had done exactly the same thing.
And here’s that config…
heat_pump_meter:
source: sensor.heat_pump_energy
name: Heat Pump Meter
cycle: daily
tariffs:
- heating
- water
This must be a bug I think, I can’t believe every meter in the system could just suddenly decide to reset itself to the previous days value for any normal reason. It’s not like the clocks changed and threw it off or anything like that.
I looked back over the last couple of weeks and it hadn’t happened in that timespan before.
Any suggestions as to the possible cause?
