I am making some progress with the Kogan RGBW bulbs. I used the template settings for the Luminea ZX-2832 E27 RGBW Bulb here and now have the RGB channels working, and used Setoption19 1 to have HA auto-discover the bulb.
A couple of problems remain, the sliders for Cool/Warm work more like a dimmer and are backwards - at 100% Cool, the bulb is fully Warm in colour, at 100% Warm the bulb is dimmed to an off state.
The brightness of the RGB colours is a little dim as well, they do display accurately though based on the colour wheel selector. So a few things left to sort out and debug, but progress is progress.
Just came across these. They have Aus cert and can be flashed with Tasmota according to this template. I donāt use Tasmota as I prefer ESPhome. Is there a way to decipher the template to get enough info to create the correct ESPhome code? If itās easy enough I might buy some of these wifi wall switches.
EDIT: just found this, so I guess itās a case of manually deciphering the templateā¦
Awesome! Thanks for the link. I guess Iāll need to get myself some hardware for serial flashingā¦ Iāve been lucky enough to get away with OTA so far
Just curious though, why do you care about it being certified? because as soon as you flash them, the cert is out the windowā¦ the cert is only valid on the hardware and software combo as far as im aware. Thats been the case with every product iāve ever worked on anywayā¦ though i am in NZ, and you Aussies are all a bit different sometimes
Yeah, I understand the thoughts on that however the main issue with regards to the safety of the device is the hardware (creapage distances etc.). Plus, if the thing catches fire no one is going to know that the firmware was modified!
for sure.
Iām in electronics myself. I donāt do a lot of mains stuff, but i can at least tell a really dodgy design from a āsheāll be rightā design and just put them in hoping for the best haha
and yeah, we should @nickrout haha
Iām in Taupo if you ever wanna come have a beer
This has the RGB working and has the brightness slider work independently of the color temp slider. The color temp slider now works (somewhat) in the correct way. Full warm makes the bulb 100% warm, full cool dims the bulb to about 5% brightness and no white light.
Iām starting to think these bulbs fake white light using the RGBs and only have warm LEDs for ānormalā white bulb color.
Still happy to donate one to someone in Aus who might have more knowledge on how to work these things out than I do.
- likewise on the beer.
