First make yourself a list of all the information you want to collect, then add the things you want to control. You have to ask yourself where you want to locate the Raspberry Pi, how are your sensors are interfacing? Do you need to hardwire them, if so how, how long will the wire need to be? Do the...

The Circadian rhythm component works but not how I thought it would. It is ment to compensate for when the sun sets. So at lights on it would be 100%, dim to minimum at noon, back to 100% for sun set. I just set my test light to "inverted: true" to get the effect. I have not played with it too much ...

I think you want to make a helper:

Had anyone played around with this yet?

I only want to control dimming and possibly on/off of the lights. The rest of this rooms environmental controls are managed by a trolmaster brand system (and a separate CO2 device since trolmaster is worthless at controlling CO2 in open loop rooms). I use a blumat automated watering system. I know ...

Lowering the integration time to the lowest setting (2.4ms) and lowering the update interval (1s) I have been able to get more uniform readings. The individual colour readings still vary +/- 10% from second to second, it is better then the 80% variance I was experiencing with a longer update interva...

I think it depends on what all you want to be able to control, and what you need for inputs. You do not need one, but they are handy and easy to deploy if you need to expand the scope of your project.

I manage my esp32 and TCS34725 with esphome. It reports R% G% B% C% lux and color temp. Even with just that my readings are not consistent at all. All my set up variables do not change, same location, same light source. At the moment I do not have a dome over it.

My readings with the TCS34725 have been all over the map. With the gain at 1x and integration_time at 700ms over a period of 12 hours my PAR out put ranges from 130 up to 430. Same location, same light, same dimming level. Sometimes the color readings are strange as well, like 95% blue 85% green 12%...
