#Sonoff #Zigbee #HomeAutomation - Věda a technologie
Great video! I'm new to sonoff as I wanted something to make dumb tech smart I.e a few lights I have in the office and garage are led strip lights, and I wanted to spend £20 per light rather than £75 x 2 for philips hue, even though my house easily has 50+. Anyway... I assume I could run this with a smart inline switch to enable and disable a bathroom extractor fan? I don't have a sonoff coordinator (hub) but do have 7+ alexas in the house, assuming it might run OK from that? Thanks, love the videos!
I tried the non display sensors on homey pro, and it works, I’ll give this one a try aswell
i use 4 sonoff zigbee temp sensors with Tasmota zigbee/Openhab and i am pretty happy.I really love the screen though so i ve got wife's approval for SNZB-02D :)
Nice! The sensor is pretty good especially considering the price.
Does it work with ConBee II
Good looking sensor Mat. Thanks.
Thanks for watching Ron hope you are well ;)
Very interesting Mat, just ordered a couple to try out. I tend to use the Aqara ones but I recognise that for some of the areas in the house my wife would prefer to see a display rather than fire up HomeAssistant on her phone. Thanks!
I'm in the same group. Display works for most popular areas, while I'm fine with bathrooms just having small probes.
Now that it's been a year. How has your experience been?
@@levi799pretty good experience, battery life is good, have not had to change them yet. Display not easily readable in low light and I find that one of them seems to drop connection on occasion, probably because of its location. I would say they are pretty good value for money.
This sensor does not work properly on smart life, it constantly disconnects and have to reset manually. Tried to update the firmware but It does not appear to have any firmware update available.
nice video, thanks!
Glad you liked it!
Very good Mat, thanks for sharing your findings. I’ll try this sensor on my Home Assistant + ZHA setup. I’m currently using a Sonoff coordinator so I think it’ll work well.
You shouldn't have any problems.
I am new to your channel and not sure you already checked the Xiaomi Mijia Bluetooth Thermometer 2 - you can get 10 of them for 70NZ$ (~35 GBP) including shipment. With very simple hack you can get them reporting to MQTT. Have more than 10 around the house and pretty happy with results (using with node-red & InfluxDB & Grafana). Anyway, thanks for informative video
That's good tip thanks. Definitely value for money ☺️
just bought 4 of those, they seem pretty cute. updating them were a hassle and figured out by trial and error. I ve made a video about update process, takes around 35 minutes for each device. I also wish they would have aaa batteries, 2450 batteries annoy me a lot. at least make them 2x cr2032 or 2x cr2025 which is pretty much everywhere. 2450 batteries are pretty expensive and very hard to find locally. I am plannning on putting a micro usb and a 3.3v linear regulator to each of them.
35 min to update or to setup the toolchain :) I hope it's the latter haha. I prefer the 2450 as they hold like 3-4 times the charge.
...the web site says not shipping till 23rd December. I've ordered a couple but looks like I won't be getting them till next year! Christmas and Postal strikes will get in the way. Many thanks for the videos - they're always interesting and just about the right amount of "techyness" for me!
I think strikes will affect some of my shipments too. It's frustrating at times to wait long but those are the modern issues :)
Let's hope the sensors stay in supply for a long time
I read it as Dec 2023
Hello . i like your video's and i learn a lot from them but can you please make a video how to make externel converters and how to integrate unkow devices in zigbee2mqtt. thank you
Its a bit of black magic if I'm honest. I'm ok with modifying some of them but writing from scratch can be challenging. The very bare concept is: you look at what's ZigBee spits out in the log and you map that data to a more recognizable format. Some devices (Xiaomi) have pretty complex converters others just use standard functions from the exiting library.
@@notenoughtech ty four the reply . i have 0 programing skils but i like to tinker , i have some livarno home smart light and on zigbee2mqtt suport page they give something lne's of code but i don't know how to use them wewre to put them.... that's why i need a basic mode how to integrate external convertors to zigbee2mqtt .
Kind regards Toma
Nice looking unit and a bit cheaper than the AQARA versions. The 2450 lasts much longer than the 2032....
I was wondering, does this sensor work well in cold temperatures long term, such as in a refridgerator? I know the Aqara zigbee sensor, without a display, can go down to below -18 degrees C and the battery life is quite good even in cold environments.
I actually never tried it in the fridge could be an interesting automation
@@notenoughtech I'd be interested in that, was wondering if bluetooth would be a better bet?
@@sven1858 Bluetooth range would be dramatically reduced by the metal enclosure of the fridge, and as BT is only about 10 to 15 metres at best of times, the extra range of ZigBee would likely give Zigbee the edge, even though the range of a sensor in the fride would still be reduced. Could be worth trying though :). My concerns would be how the battery and the circuitry and LCD cope with the lower temps :)
Hello I use the sensor with ns panel pro. When the temperature value changes by 0.5 units and the humidity value changes by 5 units, it is read on the ns panel pro screen. What is the reason.
I have no idea... Wrong units?
I am looking for a zigbee temperature sensor with an external cable sensor to monitor a hot water pipe
Though one actually
This or Aqara, any updated experiences?
Both are actually good. Aqara if money isn't the issue this one if money is the issue
Will it work with Smartthings ecosystem?
I can't confirm as I not used Smartthings
Is working with Tuya?
yes
My experience with zigbee sonoff sensors, always offline, battery don't last long, with lcd, more battery drained, why not sensor with power suply? Thanks.
Can't say I share the same experience. You could try looking into coordinator firmware change
Hi, I got this temperature sensor and I'm quite satisfied except for the possibility of changing the "comfort level settings" in the settings. When I try to change them it asks me for confirmation on the device button but even if I press the button only once nothing happens. I have firmware version 1.0.9 which appears to be the latest. I would add that it is not a problem with the device because I purchased another one and the problem is present. I would like to ask you if this problem is also present in yours and if you have any idea how I can solve it. Thank you
I have not run into this. The reason to press the button is to wake up the ZigBee component and accept the pending update from the hub (as sensors like this go to sleep between the updates). Perhaps moving it close to the router or coordinator would help?
@@notenoughtech I did it very close to the hub. If I'm not asking too much, you could try changing one of the parameters provided and see if in your case it accepts the confirmation from the device button? Thank you
I just paired with Sonoff ZB Bridge Pro -I have the same issue right now. I'm also unable to update from 1.0.9 firmware up I wonder what's wrong with this. i used it in the past for sure
@@notenoughtech I thank you! the test you just did makes me understand that the problem is widespread so I hope for a software update that will allow you to go back to using these devices. Thank you again for your test.
@@notenoughtech Hi, I would like to update you on the problem I reported to you: I contacted Sonoff and within a few days they replied telling me that they would fix the problem with the next release of ewelink. While waiting they sent me a version of ewelink (.apk) with the problem solved. Really very efficient
Oh I love it... I got to get a load of them, I use mostly the Original Sonoff Zigbee Temp Humid Sensors BUT I'm a sucker for a screen.... On another note, That Aquara TVOC Sensor with eInk display, I have one of them in used with Home Assistant via Zigbee2MQTT but it goes offline after a couple of days, Its re-Pair then couple of days it's offline again, driving me mad, I've left it offline for months because I couldn't be bothered every few days resetting it. Arghh
Your issue with the sensor going offline is a little odd. I have 4 of them and they stay online for ... Well, until I update home assistant next which is about every 2 months for me (I don't update every single time). I am using ZHA though, but they also worked on deConz the same way. Maybe it is a Z2MQTT issue?
My first step would be to check your zigbee firmware, then sofware converters. My second step would be to see if its paired directly or via router and try to figure out why it goes offline
Can alexa turn on and off AC automatically using this device?
Alexa can use the temperature data. You can set scenes based on the temperature and what you want to do next
You had higher temps in the UK than 60C? 60C is 140F -- that's hotter than any temp ever recorded in the US! (which is 134F, by the way) 3:07
Did you put it in the sun under a glass bowl?
In conservatory. Which is just a bigger version of the glass bowl really
The SNZB-02D sensor is the only Sonoff sensor that I have not tried. I have tried all the others, everything. None of the ZB sensors will stay online. they simply drop offline. I have had good luck with the RF motion sensor, but am not using it. I have 50 RF Basic and RF wall switches by Sonoff in my home. Love them. But their ZB sensors even using the ver 2 ZB hub are simply terrible and will not stay online. Wanted them to work, but they all drop offline again and again. Worked with T.S. to make them better, no luck.
If you tried so many sensors it paints the picture that your coordinator may be at fault. I can understand one of end devices giving you troubles but if you tried several and nothing changes you are looking in the wrong place
Maybe try to move the Zigbee bridge to another place as it might interfere with surrounding WiFi-signals or similar. If you have connected the coordinator directly to some home automation system via USB try to use an extension cable and move it further away.
Tired it with tuya keeps going offline and low battery… returning
Are you using rechargeable batteries?
@@notenoughtechI bought same temp.humid. sensor, 3pcs. and connected to the tuya hub via zigbee. they worked well for like 5 min and went offline even though they are very close to the hub.
Would pay 2x if it used epaper display.
Should be usb powered
I would take it as an option but not the only way of feeding it power
sheet sensor is this… don’t buy it!
What were your troubles with it if I can ask?
@@notenoughtech the temp it’s Wrong , am it’s refresing verry later, i try it to make an automatisation heating with Homey … this sensor answer to late and it s limited.. i have from Ikea wich is the best !
How much off is your temperature? Reporting should be within 30 sec on sudden changes and every 2-3 min in dormant states.
@@notenoughtech sometimes it shows once every 20 min, it once happened to freeze and I thought the temperature was correct, after I checked in the PC, I found that it hadn't refreshed for 1 hour
@@notenoughtech and it can’t be Calibrated… it is calibrated in the PC, it displays the temperature after calibration correctly, but the calibrated temperature is not displayed on the display,
