I think that’s a good time to explain why many brands do not make IR Blaster, even if they are useful.
It is hard and takes a ton of effort to develop/maintain a large IR signal library to work with major appliance brands and models. More work is also needed for the front-end design and server-side changes. IMHO, the market has made it clear that the sales may not meet dev costs, or every top vendor would ship such devices, just like a plain motion sensor.
In the end, that is a choice of vendors to make.
