C3 device real-time energy consumption

[Alex-11976]

Device type and model (or SN)

Heat Pump Wi-Fi Controller

The detail description of new feature

I would like to see the real-time consumption of the heat pump, but at the moment, I can only see the total consumption. thank you

[wuwentao]

@Alex-11976 sorry, I have two question:

1. please provide your device SN
2. is this feature supported by your device and midea official app?

Thanks

[Alex-11976]

Hello, thank you for your quick response.

The serial number of the Wi-Fi controller is 0000C3311171H120F3C29410002185H3F. I can also provide the model of the heat pump that the Wi-Fi controller manages, which is MHC-V12WD2N8-C.

Yes, the feature is supported by the device. I am attaching a screenshot of the app and a photo of the device.

[wuwentao]

@Alex-11976 your device type is 0xC3, from our document, it should be available in current support list.
https://github.com/wuwentao/midea_ac_lan/blob/master/doc/C3.md

please double check your config and follow the reamde document to enable this attribute for your device.

1. if it works well, you can close current issue.
2. if it still can't work, upload the full debug log file to current github issue.

thanks.

in addition, if you understand how to test with source code changes, there is more opening github issue for C3 device, we have some test purpose changes for C3 device new feature support.
please refer to #387 #399 #404

the PR changes available in midea-lan/midea-local#340
and the detail step also add in these issue.
just for your reference and you can also add comments in these issue.

The attribute I requested is not available among those listed in the documentation :

EntityID	Class	Description
binary_sensor.{DEVICEID}_zone1_water_temp_mode	binary_sensor	Zone1 Water Temperature Mode
binary_sensor.{DEVICEID}_zone2_water_temp_mode	binary_sensor	Zone2 Water Temperature Mode
binary_sensor.{DEVICEID}_zone1_room_temp_mode	binary_sensor	Zone1 Room Temperature Mode
binary_sensor.{DEVICEID}_zone2_room_temp_mode	binary_sensor	Zone2 Room Temperature Mode
binary_sensor.{DEVICEID}_status_dhw	binary_sensor	DHW Status
binary_sensor.{DEVICEID}_status_tbh	binary_sensor	TBH Status
binary_sensor.{DEVICEID}_status_ibh	binary_sensor	IBH Status

sensor.{DEVICEID}_total_energy_consumption	sensor	Total Energy Consumption.The first value may be delayed because updates are only sent when the device is active
sensor.{DEVICEID}_total_produced_energy	sensor	Total Produced Energy
sensor.{DEVICEID}_outdoor_temperature	sensor	Outdoor Temperature
switch.{DEVICEID}_disinfect	switch	Disinfect
switch.{DEVICEID}_dhw_power	switch	DHW Power

switch.{DEVICEID}_zone2_curve	switch	Zone2 Curve
switch.{DEVICEID}_zone1_power	switch	Zone1 Power
switch.{DEVICEID}_zone2_power	switch	Zone2 Power

As you can see, only the attribute sensor.{DEVICEID}_total_energy_consumption is available, which indicates the total consumption of the heat pump since it was first turned on. I was asking if it would be possible to display the real-time instantaneous consumption, as I can see this value in the Midea app. I assume it would be possible to add this attribute.

[wuwentao]

@Alex-11976 got it.
anyway, you still need to test with the latest PR #340 and provide me a debug log with this code changes.
also need to add a device or app screenshot display result with totla and real value when you download this debug log.

I'm not sure which one is your expected data, I will try to check with the value from debug log and app result.

I have add a debug/test document, you can refer to https://github.com/wuwentao/midea_ac_lan/blob/089e918cb5b05913ad267d14c5f032af01607bec/doc/debug.md

once PR merged, it will available in README link.

[Alex-11976]

Sorry, but I'm not very prepared to run these tests. I just started learning GitHub and Home Assistant, and I don't know Python
I'll send you a video from the app where the total and real-time data are displayed

@Alex-11976 What's the firmware version of your device (HMI, IDU, ODU, in smarthome) ?

[wuwentao]

@Alex-11976 we don't need this video.
what we need is device response data in debug log.
current integration will send a query to your device and if your device support it, it will response a message to HA.
this is what we need.

we can got this response message in debug log and try to compare it with your device screenshot, try to find out the app real-time energy value in response message, once we got the value location, we can add it and support it.

if you don't know how to do it, we just can pause it and wait for future progress, sorry.
as I can't find out which value is real-time energy in c3 device response message.

[Alex-11976]

ok thanks I understand, I will try to debug and if I can I will send you the data. in the meantime in the app I read v2.1.44(20241128)

[wuwentao]

please update to latest v0.6.6 version, it should have the latest changes, you can enable debug log via readme and upload your full debug log, and share it to us.

[Alex-11976]

Hi, I installed the update, this is what I found in the debug. Thank you

Hi, if it helps i have a similar wifi controller, its 171H120F 0000C3310171H120F2C214100148Q2CM, i can not see the current consumption in the mobile app but i can see it in the settings on the controller display itself.

Hi, thank you, with the c3 I can see it both in the controller and in the app, so I assume that the data is there somewhere

[Alex-11976]

please update to latest v0.6.6 version, it should have the latest changes, you can enable debug log via readme and upload your full debug log, and share it to us.

after I installed the update I noticed that the device temperature was set to 40 degrees and if I try to change it an error message appears erno 32 broken pipe

[wuwentao]

@Alex-11976 first of all，your debug log is only 43 lines, you just post a error message, without any debug info.
it's not a FULL debug log, we need full debug log, please follow README document in debug part, enable debug and reboot HA, to do these action.
also include all the error action like temperature set error, most of the message and error required full debug log.

finally, if you still want to check real-time energy consumption, you still need to check the value in app and try to find some info in debug log.
or post your app value and full debug log to current github issue, we can try to check it based on the value and full debug log.

so there is more error exist with you, and you should description each error one by one with detail info.

thanks.

[wuwentao]

@Fenix131313 check these value via debug log, confirm whethere it available in log, if you can't check it, just upload the FULL debug log to current issue and description your requirements, we can help you to check it in your FULL debug log file.

[Fenix131313]

i could not find the numbers. here is one of the screenshots, here the value is 1,62kw, but it fluctuated. The other values were 0,00, 1,04, 1,16, 1,51, 1,62, 1,74, 1,97, 2,09, 2,32, 2,44, 2,55, 2,67, 2,79, 3,02, 3,14, 3,25, 3,37, 3,48, 3,72, 4,07, 4,18, 4,30, 4,53, 4,65, 4,88, 5,00, 5,11, 5,34, 5,46, 5,58, 5,69, 5,81, 5,93, and 6,04.
This is in the span of 5 minutes, between 11:19 and 11:24.
Hope this helps.
