3 years ago Not as easy as it seems. In your case is even worse since dpid 101 means is a custom function. To be more clear, all the dpId over the id number 100 are custom implementation and are created by the manufacturer, not by Tuya. The good news is Tasmota will try to calculate the total energy using the data received:
23:17:01 RSL: tele/tasmota_49A3BC/SENSOR = {"Time":"2020-11-27T23:17:01","ENERGY":{"TotalStartTime":"2020-11-27T22:48:26","Total":0.006,"Yesterday":0.000,"Today":0.006,"Period":4,"Power":64,"ApparentPower":64,"ReactivePower":0,"Factor":1.00,"Voltage":13,"Current":5.000}}Perhaps will be not as good as the integrated Tuya one but is surely better than nothing. Now, about the supposed issue with voltage resolution, those are the latest data format used on a Tuya device.
1 - Total forward energy | Only report | Integer | Values range:0-99999999, Pitch1, Scale2, Unit:kW·h
18 - Current | Only report | Integer | Values range: 0-80000, Pitch1, Scale0, Unit:mA
19 - Power | Only report | Integer | Values range:0-200000, Pitch1, Scale1, Unit:W
20 - Voltage | Only report | Integer | Values range:0-5000, Pitch1, Scale1, Unit:VI will not be surprised if your device will be not compliant with those data, Tuya has changed the dpid configuration at least 2 times already for many type of devices. Paste here a log with the relevant dpid in action, I'll have a look. (NO ETA).

Have you looked for this feature in other issues and in the docs?
Is your feature request related to a problem? Please describe.
I have setup Tasmota on a Hiking DDS238-2 WIFI Din Rail Energy Meter with the following Template: https://templates.blakadder.com/hiking_DDS238-2.html, but this Energy Meter also gives back the Total kWh Value on the DpID of 101. e.g: i have a value of 30 (0x1e) on DpID101 which means 0.30 kWh Total. Tasmota currently only supports fnId 31 to 33 for Power Monitoring (see here: https://tasmota.github.io/docs/TuyaMCU/#fnid) which are Power/Current/Voltage
Describe the solution you'd like
It would be great if someone could add a fnId of e.g. 34 for Total kWh which could be mapped via TuyaMCU command, if this works it would also be great if SetOption72 1 (Set reference used for total energy) would use this Total kWh value as reference.
Describe alternatives you've considered
an workaround it to read the raw reported TuyaReceived Values, but this works only with additional software like openhab or homeassistant
