Alternate Energy Format: Values much too high

[LeSpocky]

Using a Midea PortaSplit here, ticked the box for "Alternate Energy Format" in device settings.

While #204 was fixed in release 2024.09.0 for power, the energy reading seems to be wrong. The value is expected to be smaller by (roughly?) factor 10. Integrating over Midea power values gives the same energy as measured by a Shelly Plug, so power seems to be correct. Attaching some screenshots from today: 2024-09-04.zip.

The long cyan bar on top is the wrong value from the integration. The three bars of same length below have the right values, those are reported Energy from Shelly Plug, and energy calculated by integration over Power (shelly and midea integration).

Hi, I have a similar problem. If I don't use the “Use Alternate Energy Format” mode, the values in the HA are much too low. The Midea app and also my Shelly Plug S show significantly higher values. If I check the box next to “Use Alternate Energy Format ”, the current values are correct, but “total energy” is then much too high 88 instead of 3.78 kWh Dont use Alternate Energy Format

@Wurmi1986 So for your unit it appears you need the "alternate" format for power, but the "original" format for energy?

Or is total energy just off by a factor of 10? e.g. It should be 8,88 kWh instead of 88,8 kWh?

His SmartHome App Screenshot says 8.73 kWh for the current month. If that's equal to total, then it would be new format with factor 10.

Factor 10 doesn't seem to be exactly right, but maybe good enough. The daily usage is always lagging a bit behind in the app, so the difference between 3.1 kWh in HA and 0.28 kWh in the app could be explained by that. The all-time power is also not excatly off by factor 10, but I don't know how often this is updated in the app.

iam using a Midea PortaSplit if this is important.

best regards Wurmi

if i uncheck the "Use Alternate Energy Format" it´s not correct either.

Alright I can't really find any references for the extra power of 10 but we'll give it a shot

Just a thought, would any of you be willing to run msmart-ng download against your device and email me the resulting files?

[Wurmi1986]

Hi, i will send u the files later when I am on the computer.Best regards Wurmi

With a little more instructions where to get this msmart-ng and how to run it against my device, sure.

A little info here: https://github.com/mill1000/midea-msmart?tab=readme-ov-file#installing

The command would simply be msmart-ng download <IP_OF_DEVICE>

sorry im am new to git, where can i find your email, can u send it to me?

[mill1000]

You can email me at tuckkern@gmail.com

@LeSpocky I got your email. Thank you. The files you sent appear to be the same as the ones I already had access to. Alas, no new information to gleam from them.
