> [@endy](#): > > looks like we override the commands info based on the selected `action` in every PATCH and POST into the commands endpoint, and in every boot Is that a requirement? I personally would see more benefit in _not_ having things overridden. Maybe it’s better for 90% of Bond customers to standardize, but I would say if you’re the kind of person who is POST’ing or PATCH’ing, you should be given more freedom and less Bond-enforcing-overrides. 😃 > [@endy](#): > > About states or properties, I can’t find any overriding, but worth mentioning that PATCHing is very restricted, so set it when POSTing. I suppose I should map out each scenario very carefully. I can use these States, I think. Am I missing any? And these correspond to the Feedback boolean expressions to see if the Icon should be lit up or dark? - state.timer - state.direction - state.down\_light - state.flame - state.fpfan\_power - state.fpfan\_speed - state.light - state.open - state.power - state.speed - state.up\_light I’d kind of like the ability to make custom States (and even Actions!)- such as a “color” or “temperature” State for tracking bulb colors on Fans / Fireplaces / Lamps (and an Action to change it!). I tried making an expression with a custom “feedback” State in a POST command creation, but it discarded any State which wasn’t known, it seems. `"feedback\":\"state.light==1 and state.up_light==1 and state.down_light==0 and state.color_light==3400"` Thinking maybe I needed to PATCH a State to create a custom one, I ran into a different error response - so it basically reinforces the idea that States are only allowed if they already exist on the Device (perhaps even limited to the Type of device it is) / no custom States: `{"_error_id":153,"_error_msg":"requested state does not exist"}` --- _[View the full topic](https://forum.bondhome.io/t/information-request-advanced-custom-generic-device-creation-icon-slugs-states-commands-actions/3826)._
