Been using it for YEARS, almost a decade now. ISY, eISY.. Lets go with the basics. Govee and TP-Link Kasa has not been stable for the last 2 years. Home unit has been in such horrible shape using just those 2 has been nothing but a nightmare. Now I can't even login to the Admin via Portal to configure the eISY for the new network at a client location. Then I read you're pushing new hardware. You got a Release version of Kasa and a Beta Version of Kasa, both have the cons that make it un-usable. We have basically stopped upgrading because EVERY time we do something goes ape snitz. That's not a good sales pitch. Honestly we have been Beta Testers for eISY for the last few years. Buy something for $600 and you're a beta tester. I have never heard of such a thing. EVER! And saying Beta is being nice. This isn't even Alpha worthy. To put it into a clear picture. I use to refer people to ISY left and right. I have referred zero (0) to eISY. That's the reality of it.
