I have an oven that I need to manage the temperature of, keeping it in the neighborhood of 600° C (1100° F). I have not been able to find a Zigbee-enabled solution to measure temps that high. Does anyone know if such a thing exists? If not, any ideas for how to roll a custom solution that I could integrate into a Sonoff ihost controller? I have no trouble finding high temperature probes, but none of them interface with my automation stack.
I have got mainly hue bulbs around the house, apart from a couple of places where it wasn't practical or pretty enough.
In those cases I put in sonoff in line switches so I can control them remotely. But now I'm wanting to further upgrade by replacing most of my light switches with Hue Tap dials (and add some fittings in where I tend to not want lots of light, but will need it some time). Then I can easily switch between different profiles and have guests do the same.
Does anyone know if I can get a replacement for the sonoffs that can be recognised in Hue so that I can control it with the Tap Dials?
Or alternatively any good alternatives to replacing the light switches with smart controllers?
Thanks
I'm looking for a zigbee smart bridge recommendation.
I need something I can hide in the ceiling as want to use for downlights.
I don't want a pairing button, I'm looking for another idea as don't want to pull out the ceiling to re-pair. Must work with Amazon hub, as I don't want to use manufacturers hub.
Any recommendations?
Thanks,
Hello!
I have recently begun making my home smarter, and I've run into some trouble while trying to get my Sonoff zbmini-l, which is connected to my Philips Hue bridge, to work properly. I am able to control it individually, but not through scenes or with the Google Home app. Has anyone else encountered this problem and know of a fix? Additionally, I have another Zigbee bridge, but I am unable to find the Sonoff device on it.
Thank you in advance for your help!
PS: I am very new to this.
After researching a number of various Zigbee solutions, I have come to the conclusion that Deconz with a ConbeeII is probably the best one available, covering the two HA1.2 stacks and ZLL stacks with the widest compatibility range, even better than the ZHA or Zigbee2MQTT components of Home Assistant, and also the best maintained with regurlar firmware updates. It is really an equivalent to z-way but for zigbee. It has a rest API so I am dreaming awake of a bridge for openLuup here...

Could be a good project? I may get one to play with... It could potentially enable unifying the hue devices into one network.
2.4Ghz band Zigbee, WIFI, BT, Microwave, Cordless Phones Interferences. What Zigbee channel to pick?
Kicking off this section with a quick write up on Zigbee 2.4GHz channel utilization.
Zigbee has become a very popular protocol over the past few years mostly due to its low power consumption, low chip cost (not being proprietary like z-wave was) and ease of inclusion.
It does come with a couple of downsides however ranging from single controller topography (aka single PAN coordinator) to what the title says: It uses the 2.4GHz (ISM) band which is possibly ultra saturated by other wireless protocols and even a variety of other more or less proprietary zigbee stacks. (i.e philips hue, Ikea Tradfi, Xiaomi, Plantlink etc...)
It is therefore important to make sure they don't interfere with one another.
This is a good article showing the correspondence between Zigbee and WIFI.

Interferences lead to range reduction, dropped packets, more retries and lags. I have a 2.4GHz spectrum analyzer I can post some results from. I read through the zigbee alliance presentation claiming low interference but my experience demonstrates quite the opposite. When I was using SonosNET and Hue at the same time on neighboring channels, playing SONOS would kill the philips hue network.

If it's suppose to be around 65F° then it it could be a notation error. Mixing up decimal points and decimal comma
US notation 65.5 would result in 655 when the notation is not set to imperial. E.g. EU notation is 65,5.
Still doesn't explain why it changes all of the sudden though.

Sounds like a signed value is being interpreted as an unsigned one, so the MSB is set when the temperature goes negative. I’d guess that a 16 bit value is scaled so that 32768 = 327.68 degrees. This would also be consistent with the UPnP standard representation of temperature being in units of 1/100 of a degree.
