Ill echo what most have said already. Its not zigbee totally. I will say its there implementation of it, and most likely the device handlers. The thread I have on Cree bulbs is a perfect example of it I believe. Cree Connected Bulb Reliability Why would adding more devices to a mesh cause it to be less reliable? I’ve now spent almost $150 on smart outlets just to try to push the zigbee around better with 0 improvement. Only way it got better, deleting devices. Having 25 or more bulbs of the same time it just was totally unreliable. Delete bulbs down to like 10 or 12 and I’m golden. more so, put the other bulbs or the important bulbs over on a Hue hub…0 issues.
We are the fringe users. The average user was reported to have less than 15 devices I believe. There’s people with more than 25 devices in one room. So ultimately we are not their target audience it seems. I had hoped that this product would fill that gap of openness and usability. I am a linux admin by trade, so I know how bad open source stuff can be. So I had hoped that the little bit of polish they put on these open standards would be awesome. So far I am really getting depressed with the whole system.
