Yesterday I had my first smart light globe failure in the 4 years that I have been playing with smart devices. I bought a replacement which is the same brand etc and I have managed to get it into HA. It is a Tuya based globe (using Tuya-Local integration) and everything is working properly except the white colour temperature settings. The settings are the opposite of what they should be, ie if I use HA to set it to 2700K it is a very cool white light and if I set it to 6500K is a very warm white light. The globe is in a HA helper group of 3 lights so this means that it looks different to the other 2. Any ideas why this would be happening and how it can be fixed? If I use the Tuya app to set the temperature it works fine. |

Which config did you select when you added the bulb? Were there other options listed you could try instead? (you can find the current config for your device in the Diagnostics file that can be downloaded on the Settings page for the device). |

Maybe this is what you are after ... From the Tuya Dev site, it identifies the bulb as "Laser 10W Smart RGB Bulb E27". That's actually a different brand to the others that I have even though it came in their packaging. An Amazon special! Still, it appears to work and I am sure you are on the money with it being set to the wrong config. But how do I know the correct one and how do I change it? I hope I don't have to remove and readd it as that's a lot of work with all the automations etc. |

rgbwc is the reversed compared to "normal" config. The rgbcw_lightbulb should be a match. Perhaps I should have chosen a more obvious name for this rather than just reversing the w and c in hindsight. |

OK that's great. But where can I change it? Do I just need to edit a config file somewhere? |
|
You need to delete the device and set it up again, unfortunately. This is due to the way entity ids are stored in HA, changing the config can result in completely different entities, so simply editing the config pointer would result in broken config in the general case (in the specific case of changing rgbwc_lightbulb to rgbcw_lightbulb, it would probably work, but that is the exception) |

OK I am a bit of a daredevil and there is always backups :-) Based on what you said I edited the entry in /config/.storage/core.config_entries to change rgbwc_lightbulb to rgbcw_lightbulb and restarted HA. It worked with no undue effects! I'm glad I didn't have to remove it and recreate it. That's a big job. The one thing HA really needs is a way to replace a device with a new one, ie install the new one but then tell it to "become" the old one. It may not work for all devices but for simple things like light bulbs it might. I'm used to changing a light bulb in 10 seconds. This one took nearly 4 hours! I will definitely pay more attention to this when I have to replace any other bulbs in the future. I have 3 more of these ones as spares so I will definitely get them right. |
