Diagnostics dump

No response

[mikeage]

I'm getting almost the same errors, but I was having problems for the past week or so with 0.0.52. I did not delete the integration, but I did restart HA and tried reloading the integration, so my devices still exist (although everything is unavailable; the same effect as your issue).

To be precise, these are my errors. Note that the middle one is one a different line:

Try with 0.0.55

[doron1]

Try with 0.0.55

Much better, but.
Entities are now again created, but all 6 entities under IEC Meter [12345678] are either "unknown" or at zero. Things under IEC Contract look okay.

[GuyKh]

All things related to consumption (calls to remoteReading) fails due to errors on IEC side - you can try for yourself on the IEC.co.il site..
Other than that - there should be no errors.

Please check logs and let me know

Please check logs and let me know

Sorry for the delay. Here you go:

Perhaps this fix will fix it

[doron1]

Not installable, 😢 see #323

[GuyKh]

Should d be solved with 0.0.57

[doron1]

Should d be solved with 0.0.57

It's now installable again, but the situation is still a bit iffy. The "contract" sensors seem fine, but the "meter" sensors are not perfect (and it predicts a next bill of over ILS 35K 😄 ).
The "Energy" number is equal to the "last bill meter reading" from the contract device. "Next forecast" is as I said absurdly high. Today and yesterday consumption are zero - but that might be an IEC issue (their app also doesn't show me yesterday and today right now).

[GuyKh]

Today/Yesterday consumption is from IEC.
Next bill/usage is calculated by the last invoice. There could be an issue there. Looking
