[Bug]: Internal_server_error when changing temperature

[Jurgendv83]

Describe the bug

I have a Liebherr Rci1620 fridge, when i want to change temperature, i get a error. If i change it with 2 degrees it is ok (3-5-7-9). In the fridge i only can change it too with 2 degrees. Is it possible to change the step size? so it moves by 2 degrees?

thank you,

Jurgen

Hi @Jurgendv83,

Can you please submit the logs and the diagnostic downloads above? I have no idea where the error is originating from without them (is it a Liebherr issue or an integration issue?).

Also two questions:

1. Has this ever worked on your fridge or the app?
2. You mention: "In the fridge i only can change it too with 2 degree" does this mean the fridge only allows you to set odd-numbered temperatures?

Hi, i'm pretty new with HA, i hope this are the correct files. 1. it's a new fridge that i added, the liebherr app for android works good. 2. yes, the fridge allows only to set odd-numbers. In the fridge is a touch-panel where i can select 3-5-7-9 degress, also in the liebherr app for android phones, i can only select 3-5-7-9. Jurgen

Well welcome! This does seem like a limitation of the device. The API doesn't tell us what a valid value. Can you try to see if you can fine any errors in the logs?
