Nope that just means it uses the "supported" protocol which is "Tuya/SmartLife Zigbee 3.0". Since Zigbee 3.0 protocol is supposed to be backwards compatible all devices would fit with this. Note it does not specifically say the device is 3.0.. also if you look at the pictures there is the standard Zigbee logo NOT the Zigbee 3.0 label (edit: the logos I'm referring to are not shown on the device but pasted images in one of the marketing shots).
However - since it is listed as Hubitat Compatible it should be okay. The only other things I can see are maybe voltage issues - there is some question in the comments about that or maybe a flaky device.
Sorry! My bad choice of wording... The indicator light in question is the "radio" link, I called it "wifi" just because the symbol is the same as typical wifi connectivity...
I've been doing more reading (sorry, I'm new to Zigbee/Z-Wave/Hubitat, having just sadly replaced my Insteon setup)...
The switch seems to be performing well almost all the time. So far, the only weird behavior (as I noted earlier) has been in the evening (not night) hours. My guess is possible wifi interference. We live in a condo with literally dozens of visible wifi access points. Moreover, my HE is installed less than a foot away from my own Wifi router antennas! I am going to move it farther away (although the location is such that it will still be only a few feet distance). Will see if that avoids the problem...
CE is a European mark, self-administered by the manufacturers. It has no connection with (or recognition from) the FCC.
I do agree that CE is not necessarily a good mark, because I don't think there is an actual certification, just a manufacturer's verification that it complies with the CE "rules"
There are issues with US marks like UL as well...
As I posted above, the manufacturer lists various other certifications and tests it has (supposedly) passed.
Only thing that (electrically) surprised me with this device is that there is no ground connection.
So, the next question is what WiFi 2.4GHz channel and frequency width is your router using? Using WiFi 2.4GHz at channel 1 would be ideal with your Zigbee mesh on Zigbee channel 20. This will avoid the overlap between the two devices. Also, use a 20MHz frequency width for the 2.4GHz WiFi.
I'm guessing that Diese is same a Tuya (which IS FCC certified)
Importing with a "fake" CE mark is not so hard because there is no real certification. But importing with a fake FCC mark would be very difficult.
I guess there is some level of risk with many of these devices. FCC for example, only certifies the RF frequencies, nothing about electrical safety. RoHS is only concerned with environmental impacts. However Diese lists IEC 60669 certification which I understand to be electrical safety as per IEEE standards...
No, that is not how the Tuya architecture works. Multiple independent manufacturers make zigbee devices that conform to Tuya’s zigbee cluster usage and work with the Tuya hub.
Which is why this Diese device indicates it works with the Tuya hub.
So it happened again today. Interestingly, at about the same time of day -- about 5:30pm. The switch seems to go into some mode where it is losing/recovering the radio signal... As it does this the light go out, then about 10-15 seconds later go back on. This repeats about 10!times until the connection corrects itself and then the lights remain off but can be turned on and act normally for about 24 hours. Very odd.
I'm thinking it's not wifi interference since no other devices on the HE are affected.. and I have ZigBee and z-wave devices.
So that leads me to think either the switch is defective (unlikely I think, or the failures would be more random, no?) Or perhaps a power issue. Around that time my wife is preparing dinner so frequent opening of fridge, use of oven etc. But at least one time I witnessed we had both just walked into the room and nothing was being done...
So I'm very puzzled. I'd anyone has any educated guesses, I'd love to hear them. Only common thing so far is that my wife is always in the kitchen when it occurs
I watched as she came into the room and turned on the lights. She used her open hand to reach over, and her fingers touched both touch pads at about the same time. The radio light went on and the lights started their on/off cycle until the radio reset.
So I then tried testing, and yes -- if I touch both switch pads within a second it seems to turn the switch to pairing mode! Odd that it doesn't require a prolonged touch& hold to do that.
But at least I seem to have an answer, and it explains why it never happened unless my wife had just entered the kitchen
Thanks for all the help and suggestions. Hopefully this thread may help keep someone else from going mad..
