Describe the bug
After changing from COAP to MQTT for the Shelly 3EM the values for total cumulated Consumption multiplied by 1000x

To Reproduce
Bind 3EM via COAP and let it run for some time, than switch Shelly Adapter from COAP to MQTT

Expected behavior
Values will stay more or less the same.

Screenshots & Logfiles
This shows the Problem for TotalPower but problem exists for all Channels (0-2 on value.total) as well:

Versions:

• Shelly Adapter version: 4.0.3
• CoAP or MQTT protocol: MQTT

• JS-Controller version: 3.1.6

Additional context
Either the Unit (kWh) is wrong or there is a Multiplication Error on MQTT that is different on COAP.
