[shelly] Lifetime total energy measurements provided by Shelly Pro EM-50 are missing

[embeh]

The Shelly binding for the Pro EM-50 (and very likely also for the Pro 3) is missing values for the total amount of energy measured by the device (in Wh).

This data can be collected from the EM1Data RPC endpoint:

1. for the first channel via http://192.168.XXX.YY/rpc/EM1Data.GetStatus?id=0 and
2. for the second channel via http://192.168.XXX.YY/rpc/EM1Data.GetStatus?id=1

A typical response would be
{"id":0,"total_act_energy":1234.94,"total_act_ret_energy":567893.37}

According to Shelly, the units are Wh and they told me that this number will not be overwritten after 60 days in the way the one-minute power measurements are. So in some sense those "total" numbers are what one would expect from an old-fashioned power meter.

Unfortunately, the names for these energy values are identical to some of the names in the one-minute measurements (both start with "total") but one is only a one-minute measurement total, while the other (reported via EM1Data) is the "total total"...

It would really be nice if these EM1Data values could also be collected via the Shelly binding, especially considering that Shelly somehow forgot to put these total total values into the Web UI, too.
