Hi All!
I have been reading alot about the possible velux integrations.
From what i can find - you have some options.
Either use the KLF-200 which integrates directly into HA
Or - use the “new” netamo devices.
I am not a fan of using the netamo - since it requires the homecontrol from apple.
But - looking at the price of the KLF-200 i think it’s pretty hefty - considering that i only have 1 window.
Today i can open / close it using the remote that came with it. (KLI 311)
But i have found the KLF-050 devices - which seems to be a simple remote - that can be triggered with esphome devices or similiar.
Have any of you guys tried using the KLF 050 - or anyting simlier?
The question originates 4 years ago. But until now there seems no cost-effective solution other than to buy an expensive KLF200 interface unit. This may be one interface unit more because a vendor isolates his products from other home automation systems.
I’ve made a solution with Velux KLF50 and a standard Shelly 2PM. Then you can control your Velux blinds with controlling the Shelly. And you can have also up/down buttons if you like.
To establish the control you have to connect the KLF50 with the Shelly 2PM and the optional up/down button like the attached schematic. Be careful, you have to exchange L and N at the KLF50. This does not matter since the KLF50 and the Shelly must be installed eletricaly isolated anyway. Unfortunately the Shelly cannot calibrate the blind since it cannot detect when the blind stops at both ends. If this does matter you have to use another solution.
I recently got a Velux window with a solar shutter and want to integrate the KLF050 into HA so I can use my automations.
I really like your solution!
Your wiring diagram suggests to me that the Shelly 2PM is powered by a voltage present between N and C. Is that correct?
Since I can’t find any internal wiring diagram for the KLF050, I was wondering why I have to switch the L and N connections on the KLF050.
Because it’s AC, it doesn’t matter that much, but I’d like to better understand the wiring.
