Australia - Electrically Certified Hardware

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.

Awesome news. Very cool that you are able to get those figured out. I wouldnā€™t know where to start!

I have no idea man, itā€™s just trial and error :zipper_mouth_face:

Just came across these. They have Aus cert and can be flashed with Tasmota according to this template. I donā€™t 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 itā€™s easy enough I might buy some of these wifi wall switches.

EDIT: just found this, so I guess itā€™s a case of manually deciphering the templateā€¦

Yeah should be easy to work out from template, they probably just apply to switches and led in the template to which gpio

I had one arrive yesterday :slight_smile:

Awesome! Thanks for the link. I guess Iā€™ll need to get myself some hardware for serial flashingā€¦ Iā€™ve been lucky enough to get away with OTA so far

glad my pinouts are of some use.

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 iā€™ve ever worked on anywayā€¦ though i am in NZ, and you Aussies are all a bit different sometimes :wink:

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!

Aha kiwi too! We should form a clubā€¦

for sure.
Iā€™m in electronics myself. I donā€™t do a lot of mains stuff, but i can at least tell a really dodgy design from a ā€˜sheā€™ll be rightā€™ design and just put them in hoping for the best haha

and yeah, we should @nickrout haha
Iā€™m in Taupo if you ever wanna come have a beer

Christchurch :slight_smile: - likewise on the beer.

We just need @sparkydave to go on a month or two sebatical around aus/NZ with free lodgings and beer to do our electrical installs

OK, I opened it up. I like the build quality. (Not that I am an expert here ā€¦)

and then I found the pot of gold ā€¦

this seems to be the Tuya Wifi Module. Unfortunately, TuyaConvert did not work for me.
I guess the next step is some soldering.
This guy did it: GitHub - arendst/Tasmota: Alternative firmware for ESP8266 and ESP32 based devices with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at

A project for the weekend maybe.

where can you get the netatmo hpm stuff?

Copy paste from another thread on the Kogan productsā€¦ Iā€™m making progress, but this is not my area or expertise at all

This is the best I can come up with so far after a solid 3 hours of trying different configs today.

{"NAME":"Kogan RGBW","GPIO":[0,0,0,0,140,38,0,0,0,37,141,0,0],"FLAG":0,"BASE":18}

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.

Iā€™m starting to think these bulbs fake white light using the RGBs and only have warm LEDs for ā€œnormalā€ 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.

No idea sorry I just saw them on the HPM display at the trade expo - maybe try chasing HPM?

For anyone interested I found Mitre 10 has the HPM netatmo stuff

Also got in contact with MJS Electrical and they quoted

All pricing is already including GST.

For the switches please let us know if you want Vertical or Horizontal. The price is the same for either.

1 x Starter Kit - $488.40
1 x Single Gang Switch * requires starter kit * - $86.90
1 x Double Gang Switch * requires starter kit * - $148.50
1 x Triple Gang Switch * requires starter kit * - $198.00
1 x Single Powerpoint * requires starter kit * - $117.00

ALDI had yesterday the medion smart plugs with power monitoring. They are tuya based, tuya convert no longer works.

It is very frustrating that in NZ neither mitre 10 nor Bunnings have anywhere near the options that you guys do in Aus.
