I understand this, unfortunately public forums are often seen as ways to put pressure on manufacturers to comply with a certain option one person may require. For a manufacturer and myself we can feel a bit pressured when they feel they are being pushed in public forums over a couple of threads for one connection to one device by one person so I am sorry if I come across a bit defensive. Just because another controller has it does not mean GHL can or will be pressured into having it, they have their own road map, that does not mean they wont of course.
Honestly in the years Kessil has been around we may have had 3 requests globally for a connection. when cables have to be made in the hundreds for any form of viable link there has to be a demand, currently there simply is not that demand to make a GHL cable for this, we would need to see demand in the hundreds globally to make this any sense. If Kessil wish to make it then thats different. So GHL offer DIY options for those that do want it.
Remember GHL make their own LED units this is their focus for GHL clients to have GHL controllers with GHL lamps.
