Internal server error when trying to get information from thermostat

[nkieto]

Hello, first off all thank you for finding a solution for API limits at Tado.

I have installed TadoLocal (I am not an expert linux but i did it).

Can access to my server at port 4407, and for example I can see my thermostat at device_id:2 using http://localhost/thermostats

But when I go to http://localhost/thermostats/2, I receive a "internal server error". If I change number to 1 ({"detail":"Device is not a thermostat"}), or if I user 3 ({"detail":"Device with ID 3 not found"}). Seems that TadoLocal is working, but don't know why internal server error

Thanks in advanced for any idea. Kind regards.

Found a lot of errors at server:

What do you see on /devices and /accessories ?
Only if the device is detected as some kind of thermostat it is mapped under /thermostats.

I only have a few types of devices in my home to test with.

I have changed sensible data with XXXXXX

Thanks for reporting.

In my use I almost always get the full list of devices, so I missed this in recent testing. (Getting the list is usually just as fast as getting a single item. It usually fits in a single network packet). It was very easy to reproduce😢

I just pushed a commit that fixes this issue.

Do you happen to have a log on how the pairing went?
There is still a lot of test code and unneeded logging in that code path, that we should remove in the future.

I just pushed a commit that fixes this issue.

Not sure if something is not working to me, or something I am doing not ok. Seems that is not upgrading new version

root@localhost:~# pipx list
venvs are in /root/.local/pipx/venvs
apps are exposed on your $PATH at /root/.local/bin
   package tado-local 1.0.0a1, installed using Python 3.11.2
    - tado-local
root@localhost:~# pipx upgrade tado-local
tado-local is already at latest version 1.0.0a1 (location:
/root/.local/pipx/venvs/tado-local)

Do you happen to have a log on how the pairing went? There is still a lot of test code and unneeded logging in that code path, that we should remove in the future.

I will look for. If not I will repeat pairing. Will continue tomorrow.

Thanks for helping.

[nkieto]

I reinstalled it and now works. Will continue testing tomorrow

/thermostats/2

{"device_id":2,"aid":2,"serial_number":"XXXXXXXX","zone_name":null,"device_type":null,"is_zone_leader":null,"is_circuit_driver":null,"state":{"cur_temp_c":null,"cur_temp_f":null,"hum_perc":null,"target_temp_c":null,"target_temp_f":null,"mode":0,"cur_heating":0,"valve_position":null,"battery_low":false}}

[Jan-nl]

Should I see anything when I do http://ip:4407/zones?
The response I get is: {"homes":[{"id":,"name":"Thuis"}],"zones":[],"count":0}
Number contains an actual ID.
In the commandline logging I see zones being fetched from the Tado API

Edit: restart of tado-local seems to do the trick

[nkieto]

Something is still strange.

/thermostats

{"thermostats":[{"device_id":2,"aid":2,"serial_number":"XXXXX","zone_name":"Salón","zone_id":1,"device_type":"thermostat","is_zone_leader":true,"state":{"cur_temp_c":20,"cur_temp_f":68.0,"hum_perc":53.0,"target_temp_c":20,"target_temp_f":68.0,"mode":1,"cur_heating":0,"valve_position":null,"battery_low":false}}],"count":1}

/thermostats/2

{"device_id":2,"aid":2,"serial_number":"XXXXX","zone_name":null,"device_type":null,"is_zone_leader":null,"is_circuit_driver":null,"state":{"cur_temp_c":null,"cur_temp_f":null,"hum_perc":null,"target_temp_c":null,"target_temp_f":null,"mode":0,"cur_heating":0,"valve_position":null,"battery_low":false}}

null message when trying to recover information from thermostats id, but with thermostats works ok

Thanks in advanced.

[rhuijben]

To fill that info the cloud connection should be setup, or the zones should somehow be inserted in the SQLite db in another way.

There should be some very basic rest support to do that, but the cloud sync is the much easier route.

[rhuijben]

The hardware doesn't expose any zone info on the homekit level. What you currently see on the thermostat (and the accessory behind that) is 100% of what is available.

[rhuijben]

Is this resolved with the current version?
