OpenDTU v24.2.12 breaking API changes

[mapietru]

Just tried the latest version of OpenDTU, but as expected dbus-opdendtu stops working. I had to go back to v24.1.26...

"REAKING CHANGE: Web API Endpoint /api/livedata/status
To reduce the heap usage it is necessary to send the inverters one by one instead of a huge response. A simple call to /api/livedata/status returns just some very general information. If detailed inverter information are required the inverter serial number has to appended ?inv=<serial number>.
The websocket also returns only one inverter at a time. It as to be assembled at client side."

Thank you for sharing. We will have to implement the newer firmware by time. You don't have the output of the JSON, don't you?

just tested with openDTU [v24.2.12]and run in the same.
json of api/livedata/status
{"inverters":[{"serial":"xxxxxxxxx","name":"xxxxxxx","order":0,"data_age":0,"poll_enabled":true,"reachable":true,"producing":true,"limit_relative":100,"limit_absolute":xxxxxx}],"total":{"Power":{"v":382.6000061,"u":"W","d":1},"YieldDay":{"v":378,"u":"Wh","d":0},"YieldTotal":{"v":1578.530029,"u":"kWh","d":3}},"hints":{"time_sync":false,"radio_problem":false,"default_password":false}}

The new version provides much less compared to the v24.1.18.

Just swapped to 24.1.18 as this was my last stable version.

First get inverster and serial numbers:
/api/livedata/status
https://www.opendtu.solar/firmware/web_api/#get-common-live-data
second:
/api/livedata/status?inv=inverter-serialnumber

We have to query every SN now separately:

@henne49 i just anonymised the serial number and name, as well as the limit_absolute.

same issue here... with the last version we have to request the data by inverter :O

[henne49]

inverter_details.json
status.json

[2bbionic]

ran into the samme gap :D
anyway, I collected and anoned the JSON files for you - just in case you should need them.
I use three H350; tied together in OpenDTU
status.json
inv-status.json

[henne49]

I have created a PR which should fix the API change and work with old and new API, please test the PR, if you can.

It seems that at least the power of my individual panels is shown now - but not the summary yet:

The wattage itself fits and the log ("current.log") remains empty
There's a strange behaviour though - in my remote console the wattage is shown:

VRM has a delay sometimes. The remote console should show the correct data.

@henne49 many thanks!!
Just upgraded the DTU to latest [v24.2.16] and the dbus-opendtu as well, working as accepted.

[2bbionic]

VRM has a delay sometimes. The remote console should show the correct data.

My Cerbo has obviouly issues with transfering its data to the portal - -don't know why.
Anyway - data are received correctly from the OpenDTU and injected to the GUI.
Thanks!

Just upgraded opendtu to v24.2.16 and can confirm venus os and vrm portal are working fine with dbus-opdendtu-1.1.0. Thanks for the quick fix!

[Ayo91]
