Yes, and they both work, in addition to the CLIs paired with them also working.
Note that I’m currently using the KLF-200 in its contact-closure mode to operate 5 skylights; I’m not using the wired ethernet interface via HA to control everything that it has in its database, but I don’t see why that wouldn’t work, too. I do expect to try that out someday, if only to get the open/close status of my skylights. But, it’s a lower priority than other ToDo items on my list right now.
I started by getting all the CLIs into the Touch (KLR-300), then followed Velux’s instructions for the KIG to learn from the Touch, then my above procedure from the KIG to the KLF. I’m pretty sure that the order in which you bring these multi-item products online does not matter, but definitely how each of these multi-product controls “learns” from the other matters: I believe the important thing is that when you share from whatever device you have, you use the “security key” icon to send everything that it knows. That way the new device doesn’t try to create new security keys with your products (skylights, blinds, shades, etc.). That’s important because each product apparently can only have 1 or 2 security keys.
After doing all this, I’m also able to get new CLI keypads to work as well - but instead of them pairing directly with the product, I send from the Touch to the CLI via Velux’s documented steps. This is kind of handy if you also use some CLIs because it means you don’t need to keep/maintain a CLI for each product for future pairing of other CLIs. For instance, I’ve got a CLI in a room that operates all 8 of my downstairs shades, handy for watching TV in the daytime. So I keep at least one Touch that can control all products.
Tips for the Touch:
• If you create Groups, you can put a product into multiple Groups without issue.
• Any product in at least one Group will not by default show up on its own.
• If you press and hold on the Group letter, it’ll open up and show you the products inside it so you can still control them individually.
• I numbered my skylights with a different first number to indicate level, but you could use that for room. For me, 1,2, 3, etc are the lowest level on the first floor; 11, 12, 13 are stacked above them on the first floor, and 21, 22, 23, etc are on the second floor.
• For Groups, I used the first letter of the room (“K” for kitchen, “B” for bedroom, etc.) to help remember. In this regard I think the older KLR-200 has a better UI since you can at least name things.
• The range of the Touch is much less than the KIG/KLF. I’m guessing this is related to the Touch being battery powered while the other units are mains powered. Note you can have KLR configured as a range extender for your Touches, if that’s important to you.
