GU10 RGB simple (WiFi?) mood lighting controllable from Raspberry Pi


Recommended Posts



Have any of you played with lamps such as:




that I could control from my off-grid Raspberry Pi vi my network/WiFi (or even the RPi’s own WiFi or Bluetooth at a pinch) without an expensive hub or complicated protocol?


(In case it helps, I *do* have a recent SmartThings hub sitting unused at the moment.)


My aim is to provide a ‘mood’ lamp driven by how much power we are pulling from the grid, that gets more fierce as demand gets higher especially at peak time, but that is only on when that lighting circuit is on.


I'd like to try one first, and if it works probably add a second one...


Note that I already have grid import/export and grid intensity available in real-time (ish) on my Raspberry Pi...


Being relatively efficient (60lm+ per W, and no huge background draw) would also be good!

I've done this quite a bit with B22 bulbs, in principle GU10 should be very similar 


- I flash all mine with custom firmware that connects to Home Assistant locally rather than use the stock images that have depend on a Chinese server

- unless you enjoy a lot of disassembly and look for devices that are known to work with tuya-convert so they can be reprogrammed over WiFi

E.g. this review (different bulb) looks promising


I've had good success with Teckin


- if you already have Home Assistant, ESPhome has a really easy learning curve and is frankly brilliant. Having originally set out to connect everything via MQTT I've now switched to avoiding if at all possible! 

- the quality of light from the bulbs themselves is so-so. I find it fine for "accent" or secondary lighting, table lamps etc in portable fixtures where wireless control makes a lot of sense, but for my primary wired lighting I'd avoid them both for quality of the light emitted and general dislike of over reliance on wireless

- just yesterday I wrote an ESPhome extension that allows me to control them directly from loxone too, no other bridge or server needed. I'm very pleased about this as if means I can have one system control all my lighting (wired and wireless) from one interface.
