HMT 2250 6T - No AC Power Data

[Sonnenwerk]

With my DTU/Device Combo, i get the DC information for each port, but the AC values and the temp and some others are missing. Any input i can give you to add this information ?

[suaveolent]

Thanks for reporting.

Can you maybe post the output from the get-real-data-new and get-real-data commands from the hoymiles-wifi lib? https://github.com/suaveolent/hoymiles-wifi

Please only keep the first 4 digits of the inverter serial number.

Alright got it.

This is a three phase inverter. I need to refactor the code to suppor these two. Might take some time though.

If you want to manually read them in the mean time you can change line 83 of the sensors.py from key="sgs_data[<inverter_count>].active_power", to "active_power",

and line 124 from key="sgs_data[<inverter_count>].temperature", to tgs_data[<inverter_count>].temperature.

I guess i am not so sure with that changes - and if it still does an autoupdate update later on, if i change the values now. So i will just wait ..thanks already for replying that fast !

[suaveolent]

@Sonnenwerk I just pushed support for three phase inverters. You can try it by updating to main branch.

You need to delete the device config first and then set up the integration again for it to work properly as I did not implement any migration functions.

Please let me know if it works as intended :)

[Sonnenwerk]

I deleted the devices and the ip-adress. Then i did a restart..but then..i guess i did not the right things. Currently when i install pip install hoymiles-wifi i get version 0.2.1. Github says latest release 0.2.3. So i uninstalled with pip uninstall ... and reinstalled.

Restored my backup from yesterday and tried again. Hoymiles new install shows 0.2.3 in ha, but the inverter still does not show a name. i tried to import the repository with https://github.com/suaveolent/ha-hoymiles-wifi ..is this the right url to input as a repository ?

[suaveolent]

Yes it seems right, but what you need to do after install is „upgrade“ to main branch since I did not yet release a new version.

So:

1. Remove configuration
2. Go to HACS and redownload Hoymiles but select „main“ as version
3. Configure your DTU again

[Sonnenwerk]

Hmm..that update worked..but i just can see one DTU now and no inverter..is this maybe related to "night". I will check tomorrow. --> i re checked the update..was too fast yesterday. i can see "main", and i can select it, but it is not taken into the field value.so my yesterday update was to 2.3 again.

[suaveolent]

You are right, I experience a similar behavior. I will push a new version tomorrow. Maybe this will help.

[suaveolent]

@Sonnenwerk I just pushed a new pre-release version 0.2.4-dev.

To install it proceed as follows:

1. Delete any existing configuration
2. Navigate to HACS
3. Click on "Redownload" for the Hoymiles integration.
4. Enable "Show beta versions" and select 0.2.4-dev
5. Restart Home Assistant
6. Setup your DTU

Now your inverter should show up.

[Sonnenwerk]

Installation works fine now. Results are as follows:

1. My HMS800W-2T is identified as a HMS1000-2T
2. The name of HMT2250-6T is correct
3. The Model information from DTU of HMS is now displayed with it´s name "DTUBI..." instead of it´s model type (integrated or whatever)
4. The HMS DTU has a value for "AC daily total" the HMT field for it is "unknown"
5. The HMT itselfs shows a lot of different values (temp/version/DC), but no AC values at all (despite net frequency).

[suaveolent]

Thanks for testing.

1. Can you maybe send me the first 6 digits of your serial number?
2. Great :)
3. DTUBI is expected since this means the integrated DTU.
4. It seems like the DTU does not report the AC value. I need to look for another way.
5. yes this is expected since the DTU does not report it for the Inverter.

[suaveolent]

Alright that’s a bummer. This means I cannot distinguish between 800W and 1000W.

I need to combine them as 800W/1000W

[Sonnenwerk]

Can you look into those values, please ?

pv_vol: 2293 pv_cur: 2308 pv_power: 2285 pv_energy_total: 3983

I only get one of those values. I guess it is pv_cur.
