I wonder how accurate is shelly really?
I'm comparing the values I get from electricity company and shelly.
Import
1 October: 22.78 kWh (real) 24 (shelly)
2 October: 30.59 kWh (real) 32.1 (shelly)
3 October: 25.69 kWh (real) 27.3 (shelly)
4 October: 30.19 kWh (real) 31.4 (shelly)
5 October: 37.33 kWh (real) 37.5 (shelly) almost correct...
And export(returned) is even worse
1 October: 8.29 kWh (real) 9.51 (shelly)
2 October: 0.15 kWh (real) 1.6 (shelly)
3 October: 0.79 kWh (real) 2.3 (shelly)
4 October: 0.25 kWh (real) 1.4 (shelly)
5 October: 0 kWh (real) 91.4 (shelly) ??????
Is the calibration wrong, I thought it should be around 1% difference (99% correct)
