.... If they can be controlled directly from HG, they would be a nice replacement for appliance modules.
No. It's a cloud-based world on this side of the millennium. Only the old-school, old tech isn't cloud based. Don't forget....
everything is locally controlled... using the switch.
...... if they are only controllable via cloud based phone app they might as well give them away for free.
The way these wifi Smart device manufactures are coming and going now a days they could be bricks before you open the package.
It wasn't that many years ago..... we used to buy boxes of incandescent light bulbs. We did so knowing full well that they would only last a few hundred hours. Then the expensive lights would have to be disposed of and replaced as the were completely UN-repairable. It is very possible that these modules may fail to function in the very near future. The same can be said for some,
or even many, of the various brands of modules sold today. I use enough different brands that it's unlikely my entire system would just crash because of a corporate bankruptcy ....
AGAIN.
But at five bucks a module..... they will likely be cheaper than the old light bulbs once used in the very same locations.
Don't forget....
although there are MANY valid forms of Home Automation... lighting control isn't enough for many of us. And without the collective AI smarts only available via the use of Internet connectivity.... it's impossible to have a modern smart home. So far..... I've been able to keep building and improving my automation setup..... without a fee-based plan. And to do so.... I think I can live with another brand-name (or even protocol failure).
It would be nice however.... if some smart code writer created a server based site that would allow various phones, modules, protocols, and control software to integrate. Although Amazon is doing a pretty good job at that anymore. It has all turned into a huge corporate mainstream industry. That wasn't MY idea... or my choice. But I've always believed that exploiting this technology means accepting what is available and working with that.
