Brightness value set to "null" causes DiyHue to fail to start

Description

Both with the HA addon and standard host install, the app will fail to restart with the below error

If i go into the lights.yaml and ensure that any bri values are set to 0 rather than "null" it starts fine. However i am unsure what is causing the null values rather than 0-255.

Errorlog:

Traceback (most recent call last):
  File "/opt/hue-emulator/configManager/configHandler.py", line 114, in load_config
    self.yaml_config["lights"][light] = Light(data)
  File "/opt/hue-emulator/HueObjects/__init__.py", line 291, in __init__
    "data": [self.getV2Api()],
  File "/opt/hue-emulator/HueObjects/__init__.py", line 532, in getV2Api
    "brightness": round(self.state["bri"] / 2.54, 2),
TypeError: unsupported operand type(s) for /: 'NoneType' and 'float'

Steps to reproduce

Unsure when/why brightness values for random lights will get set to null but doing so manually would allow the issue to be reproduced

Please enter your operating system details here

Ubuntu 22.04. However the HA addon has the same issue

What DiyHue version(branch) are you using?

master (latest)

Changed

if "bri" in self.state: result["dimming"] = { "brightness": round(self.state["bri"] / 2.54, 2), "min_dim_level": 0.10000000149011612 }

to

 if "bri" in self.state:
            bri_value = self.state["bri"]
            if bri_value is None or bri_value == "null":
                bri_value = 1
            result["dimming"] = {
                "brightness": round(float(bri_value) / 2.54, 2),
                "min_dim_level": 0.1  # Adjust this value as needed
            }

seems to be checking for null values and changing to 1 if not.  Sort of fixed it?

[mcrummett]

i also had to change

if "bri" in state: v2State["dimming"] = { "brightness": round(state["bri"] / 2.54, 2)} v2State["dimming_delta"] = {}

to

if "bri" in state: bri_value = state["bri"] if bri_value is None or bri_value == "null": bri_value = 1 v2State["dimming"] = { "brightness": round(float(bri_value) / 2.54, 2) } v2State["dimming_delta"] = {}

from my understanding this was due to me adding scenes to my configuration and it loading the light values differently.

[mcrummett]

If I can work out how too, then yes haha

Create a fork of this repo, commit your changes in your fork, then use the pull request button to create a pull request in the main repo. I think there is plenty youtube videos with these steps...

[mcrummett]

Top dollar. will do it over the weekend, cheers!

Hey, I have this problem, too, using the official add-on in HA. @mcrummett Could you create the PR please?

[mcrummett]

Sorry yes. I’ll try and do it tonight. Been rather ill this last week so not had a chance

I did as per above and removed the bri: null from the lights.yaml and started fine. I forked but can't understand what has been updated by @mcrummett as one is commented out in main branch anyway and other code looks as per main. Workaround is to just edit the lights.yaml to not have bri: null (set to 0 for example).

[mcrummett]

The values will go back to null next time the lights are turned off. My changes make it so that if null is found it changes it to 0 and thus doesn’t error

I know, just couldn't figure out what you've done. Hopefully you have time to create the PR. If not I'll have a look when I get some time :)

All the best Mark @mcrummett
