Hello

I just integrated the DEVEMEL integration and I control all my SOMFY IO and RTS shutters, I have a Tubauto gate and it gives me an error when I want to integrate it to Gladys I copied the Json file as described in the Doc

I don’t know if you can help me here is the code

HTTP 422 — UNPROCESSABLE\_ENTITY — t\_device\_feature.min cannot be null; t\_device\_feature.max cannot be null

Thanks for the report

This is normally fixed in version 2.0.3

**The cause**

- Your Tubauto portal is declared as a « button » (type 4096).
- In Gladys, each function of a device must have a min and a max value.
- The integration code did not set these values for 3 cases: the button (portals, garages), the switch (type 4097) and the on/off of the lights (type 4100).
- Gladys therefore refused to create the device, hence the 422 error.
- Shutters already have these values, which is why they work.

**The fix**

- I added min: 0 and max: 1 to the 3 cases, in src/devices/button.js, src/devices/switchDevice.js and src/devices/light.js.
- I added a test that checks that each function has a min and a max. Without the fix, this test fails. With it, all 249 tests pass and the code check is good.
