ZigBee hub is included with Echo 4th Gen, and Echo Plus 2nd Gen. NB Both Echo 4th Gen and Echo Plus 2nd Gen have their own built-in temperature sensor

[@tumiwisizm]

i've just paired zigbee sonoff smart switch with echo 4. worked after few attempts. you dont need to download any apps, just pair it with echo. for me it power off, power on and quickly say to alexa discover new devices

[@MaiconSantosBR]

Is your snzb-02 temperature sensor getting connected without problems? Here it is not working. I add it directly to my Echo (4th gen) but after a few minutes it is unavailable and I need to remove and add again but it is only available for a few minutes.

[@carlobernasconi7480]

I had the same issue two moths ago. Then got it working for a couple of months, but this morning is offline.

[@davidhardy418]

If you add this as a favourite on the app does the temperature appear on the homepage when you open the Alexa app?

[@Inchkaka]

On mine I have to tap on the sensor to see what the temperature is, so I'd say no!

[@reboucasaraujo]

Can I connect the humidity sensor directly to Alexa Echo 4th Gen without having to buy the sonoff bridge?

[@Inchkaka]

I'm not sure if the 4th Gen comes with Zigbee built in. Worth googling, but one of the comments here suggests you can!

[@RomanNikitchenko]

(y) Interesting, liked the experience... but you lost half of the functionality. This is an T/H (temperature / humidity) sensor. And actually not bad. Pity their own hubs are low quality - but sensors are actually good.

[@Inchkaka]

You're right, it only sends temperature to Alexa, not the humidity information.

[@hasakidis]

can you connect the sensor directly to ewelink app as a standalone device?

[@Inchkaka]

I'm actually not sure, I can advise on the Alexa/Zigbee integration, but not the ewelink.

[@GroupNuzil]

Are you able to create a routine if the temperature is above or below a certain range to trigger a smart home device?

[@Inchkaka]

Yes definitely, that's what I use it for.

[@fudpukker]

Ok, so what about the humidity reading?

[@Inchkaka]

Not supported, which is very annoying!

[@powerbastion1083]

That’s why I watched your video as I hoped you would comment on that - but you seemed to miss it

[@omastria]

Thank you a lot for the video. 2 questions. This sensor can connect with tuya hub (Zemismart)? And, I have a TH sensor by Zemismart but isn't available to use it as trigger on Alexa. Did you do some configuration? This sensor still works on Alexa as a trigger? Thanksssssssss

[@Inchkaka]

I'm not convinced it can. I think it either needs the bridge or a zigbee capable device. I'm not sure though.

[@omastria]

Can we use this sensor as a trigger in Alexa? Tks

[@Inchkaka]

Oh yes. I get it to turn on a smart plug that the heater is connected to, and turn it off when it hits a set temperature. It works really well.

[@directorski]

@@Inchkaka How? unable to create routine from this device in Alexa? doesn't show up in Alexa Smart Home.

[@Inchkaka]

Does it show temperature on Alexa app devices tab? Check my blog for step by step... inchka.blogspot.com/2021/09/controlling-alexa-smart-home-devices.html

[@directorski]

@@Inchkaka yes shows up as a device in the devices tab, but not a Smart Home Device, so can't create a routine.

[@directorski]

@@Inchkaka yes shows the temperature

[@applesebyable]

It didn't work for me either. I'm using an echo dot 4.

[@Inchkaka]

The echo dot 4 doesn't have ZigBee built in though, does it? I didn't think it did.

[@SeikoLeaks]

Hey mate same question as vimal, can the temp sensor trigger a routine once a set temperature is reached?

[@Inchkaka]

It can. Mine turns a plug on if below, and turns off if it's above a temperature. It's done by a simple Echo Routine.

[@SeikoLeaks]

@@Inchkaka thanks for the info I'll definitely be getting some, I can now finally get my heater to turn on automatically when it's cold at night 👍

[@fuzzymonsters]

@@Inchkaka could you do a video on this?

[@fuzzymonsters]

@@Inchkaka I had the device add to my alexa, via the sonoff hub, and it doesn't show in list of devices able to trigger routines.

[@hathingenioso]

which app is?

[@Inchkaka]

The Alexa app

[@trufalex]

not work for me

[@Inchkaka]

Which bit didn't work?

[@JustinPeterAustralia]

Your video is wrong. You have to connect the sensor to eWeLink app first before adding to alexa app.

[@GroupNuzil]

Not necessarily true - If you have an Echo that has a buil-in Zigbee Sensor, you can skip the eWelink app.

[@Inchkaka]

This is for Echo devices with ZigBee built in. You don't need eWeLink for those as I mentioned :)

[@edugondo]

@@Inchkaka Do you know if it works with a Echo 3rd generation? I know that the 4th gen works.
