Mi light controllers

[Andy Cook]

Hi Martyn and Alex I think weee looking at the mi light controller system in the past.

Did you guys ever find out if there was more then 4 channels?

Also do you have the link to the git hub for it?

Thanks

[Robin Wood]

We used these in the SteelCon kids track. One of the guys has a github repo with python libraries for controlling then. I'll try to find them if you want.

Yes please! That would be great!

It is lua not python but they reckon you should be able to work out what is going on.

Tom... Take a look at this site, the bulbs are badged up differently but look identical to the mi lights?

It's also worth noting that the latest firmware for the rflink which is
a mega + 433m+2.4g radios (that we have in the space) supports milights.

Couple domoticz with that and you have a nice web gui for anything 433,
and milights as well.

Thanks Martyn,

I need a wifi controlled LED dimmer that is 230v powered and dims LED lamps? Any suggestions

[Tom Hargreaves]

Yep. I think all of the milights/easybulbs/limitlessleds are identical.

Sadly, they seem to have been designed around the handheld remote
control, with the wifi bridge very much as an afterthought, to the
extent that the on-air protocol is basically a one-to-one mapping of
remote buttons.

Specifically, this means: (a) you get the RGB LEDs illuminated or the
white LEDs illuminated but not both simultaneously; (b) RGB control is
limited to hue and brightness, which really doesn't cover much of the
colour cube; (c) there are only four groups of individually-addressable
bulbs.

(c) can be fixed in software by syncing a maximum of four bulbs to a
given remote ID, and having the transmitter pretend to be lots of
different remotes. Remote IDs are 16 bits so that allows individual
addressing of 2^18=262144 bulbs. Whether the existing wifi bridges
can be persuaded to do this is unclear.

The other problems are embedded in the firmware. To that end I would
like to disassemble a bulb and dump the flash (it has an STM8S003F3[1]
inside; here's hoping they didn't bother setting the protection bits),
to see whether there are any undocumented commands that might be more
useful. A rewrite would be possible but I have very little hope that
it would be possible to undisassemble a bulb back into its original
condition after reflashing, or that such a procedure would be easy
*sigh*.

Tom.
