Aeon Labs DSB028 - Indigo does not parse energy reports?

I have two of the Aeon Labs Home Energy Meter 2nd Edition (HEM G2) (DSB028-ZWEU or DSB028-ZWxx where xx = country/region it is made for).
Both of my units are the 3 phase 4 wire version made for EU.

One has firmware 1.5 and the other one has firmware 1.8.
I have discovered when looking through debug logs that it seems that Indigo does not parse energy reports for my unit with the newer firmware 1.8?!
I do see energy reports showing in the debug log but Indigo does not populate it to the GUI and nor does it parse it.
It works fine for power reports and for firmware 1.5 it works fine for both power and energy reports.

This error has most likely been there for ever and has not shown up after my switch from the S2 stick to the S5 stick but I will dig into some old debug logs when using the S2 stick.

Here are 2 examples of power load total reports for DSB28 Home Energy Meter G2 with firmware 1.5 and as you can see they are properly parsed by Indigo:

And here are 2 examples of power load total reports for DSB28 Home Energy Meter G2 with firmware 1.8 and as you can see they are also properly parsed by Indigo:

Code: Select all

   Z-Wave Debug                    RCVD requestMeterLevel: 01 14 00 04 00 51 0E 32 02 21 74 00 00 58 E8 00 00 00 00 00 00 65

   Z-Wave                          received "Energy Meter - Garage - TOTAL" power load to 22.818 W

However, moving over to the ENERGY reports now. Here are 2 examples of energy total reports for DSB28 Home Energy Meter G2 with firmware 1.5 and they are properly parsed by Indigo:

Code: Select all

   Z-Wave Debug                    RCVD requestMeterLevel: 01 14 00 04 00 1E 0E 32 02 21 64 00 03 50 13 00 3C 00 03 4F FD 47
   Z-Wave Debug                    . .  requestMeterLevel: node 030, endpoint None, meterType 01, raw value 6400...
   Z-Wave Debug                    . .  requestMeterLevel: 217.107 kWh (float: 217.107000)
   Z-Wave                          received "Energy Meter - House - TOTAL" energy total to 217.107 kWh


Code: Select all

   Z-Wave Debug                    RCVD requestMeterLevel: 01 14 00 04 00 1E 0E 32 02 21 64 00 03 4F FD 00 3C 00 03 4F EC A7
   Z-Wave Debug                    . .  requestMeterLevel: node 030, endpoint None, meterType 01, raw value 6400...
   Z-Wave Debug                    . .  requestMeterLevel: 217.085 kWh (float: 217.085000)
   Z-Wave                          received "Energy Meter - House - TOTAL" energy total to 217.085 kWh

BUT look now at the ENERGY reports for my DSB28 with the NEWER firmware version 1.8:

Code: Select all

   Z-Wave Debug                    RCVD requestMeterLevel: 01 14 00 04 00 51 0E 32 02 21 64 00 00 00 11 00 3C 00 00 00 11 F9
   Z-Wave Debug                    . .  requestMeterLevel: node 081, endpoint None, meterType 01, raw value 6400...
   Z-Wave Debug                    . .  requestMeterLevel: 0.017 kWh (float: 0.017000)

Code: Select all

Z-Wave Debug                    RCVD requestMeterLevel: 01 14 00 04 00 51 0E 32 02 21 64 00 00 00 11 00 3C 00 00 00 11 F9
   Z-Wave Debug                    . .  requestMeterLevel: node 081, endpoint None, meterType 01, raw value 6400...
   Z-Wave Debug                    . .  requestMeterLevel: 0.017 kWh (float: 0.017000)

As you can see above the energy reports for firmware 1.8 are indeed received by Indigo but they are not parsed and reported back to the GUI for some reason?
Same problem is for the 3 individual clamps as well (endpoints 1 to 3) and only for the energy reports. Power load reports works fine for both total reports and individual clamp reports for both firmware 1.5 and 1.8.

I have emailed Aeon Labs (Aeotech support page: https://aeotec.freshdesk.com/support/home ) and asked for release notes and difference between firmware 1.5 and 1.8 but maybe you can already now see from the debug logs what is going wrong with the energy reports for firmware 1.8?

Are you sure it isn't working? Indigo only logs the new value if it has changed from the previous value. In your example above the value reported from the meter is the same (0.017 kWh), so Indigo neither logs it nor triggers any state changes (because the state hasn't changed).

Aaah, I feel so stupid now! I have deja vu feeling that I have asked a similar thing about temp sensors for 2 years ago...

I do see energy updates in the log as soon as the accumulated energy usage has increased big enough to cause the number being reported from the unit to change 0.001 kWh.
Example:

Code: Select all

Z-Wave                          received "Energy Meter - Garage - TOTAL" energy total to 0.020 kWh

Case closed!

Unless there is another issue with how the device with the newer firmware 1.08 is calculating energy usage since I see approximately 20-50W power load on average per hour so for 24 hours I should see an total energy usage of approx 0.48kW to 1.2kWh but the device is showing only 0.30kWh. I guess it could actually be that the average load is far less than I see when graphing the load. I´ll keep monitoring this but as far as it goes for Indigo not parsing the data properly, that case is closed. I promise not to ask again..
