Sorry, I am not interested on this device at this time, I have already planned probably at least 3 months of work for this project here .. : )
There is a working solution in Hubitat for IR blasters : Broadlink IR/RF remotes integration (RM3 Mini, RM Pro, RM4 Mini/Pro)
It works excellently, I am controlling 2 x Fujitsu Air Conditioners and one old Sony TV in 3 different rooms using 2 x Broadlink RM3 and RM4 Pro.
