Thinkgrow model h dimming without trolmaster

Anyone have any of these and figured out the dimming on them? Ive tried 0-10v, pwm, nothing seems to budge it.

Not interested in a trolmaster, have an existing HA setup. Was given some to try but struggling to figure out how to dim them.

Found some literature that says something about a digital dimming protocol but unsure if thats accurate or not. Noticed inventronics has a uart "digital dimming" series ....hoping its not that.

Anyone have any insight it would be much appreciated.

EDIT: found this from agrowtek:
"ThinkGrow LED fi xtures use a digital protocol to communicate. An adapter is required to drive ThinkGrow lights using a 0-10V controller like the DXV4. Adapter LMA-9 is available through ThinkGrow. "

There seems to be no mention of this LMA-9 adapter anywhere.

Does you light have a rj port on the light?
(telephone socket)

it has a 4pin waterproof. I chopped one of the cables in half to connect with wagos while testing.

There seems to be a maze of adapters available ... even their own from trolmaster appears to use multiple pieces. 1 that comes rj12 from trolmaster to an "adapter", then r12 out other side. Next it connects to a r12 to 4pin waterproof.

Yes that adds up 4 pin, like a telephone socket?

The odd thing is im seeing 11v+ out 2 wires and 5v out the other two with a multimeter. There is an adjustable red spectrum so i suspect this is why ... possibly two different channels to adjust.

Sorry bro that's above me, I hope you get it figured out.

can you decipher the exact type of driver used?
you could be very well right with the digital protocol
