Can you buy more sensors
Don't want to link to any smart devices - just wi-fi. is it easy to connect to the app and can i just read the temp and rh info via smart life app?
what is the range of the Wifi in meters

Just works 👌 astonishing little thing!

I bought this hygrometer for my cigar humidor. I decided to move on from the analogue hygrometer and what a perfectly right decision this was!This little thing keeps me informed 24/7 if my cigars aren’t at a perfect 69%. I plan to buy a couple more for other cigar storage.It’s a little bit wonky how you get it connected but when the app doesn’t find it, it will walk you through connecting to the devices’ own wifi and then from there it will add itself to your home wifi - the same way Alexa connects itself to your home network. Very clever and easy (in the end).I have found it extremely accurate. I know my humidor will be at 69% because I use the Boveda pouches. Despite this, the app shows it at 70% which, for my purposes, and taking into consideration the cost and convenience, will do me nicely thank you very much. Whilst humidity itself is quite literally relative, the accuracy for me is also relative - so I just have 70% as my norm and any fluctuations that I need to act upon are all relative to that baseline. So whether it’s 69% or 70% that it shows, it doesn’t matter.With that said, it would be nice to be able to calibrate the hygrometer but I haven’t found a way to do that?So far I haven’t got the alerts working for the hygrometer even though another device I have in my Smart Life app manages to alert me correctly. Not sure why the hygrometer doesn’t do the same (I have keenly set up the rules).EDIT: notifications for the hygrometer now working, unsure whether changes 🤷‍♂️

Real time monitoring?

As others have mentioned they work quite well but don't deliver on all they promise.The temperature only updates once per hour and that seems to happen at different times for each device. I can't see anyway to change this.They work with Alexa once added to a room but will only tell you the latest temperature received in the app and not the current temperature.The ability to download the data works but you have to download regularly for the maximum data. Downloading a years worth of data will not give a reading for every hour and you have to download for each device. The downloads links also arrive via email eventually, so not the easiest.Data sent is what is shown in the app, so daily is every hour, monthly is daily average, and yearly is monthly average.

Works well with Home Assistant

I use this via Tuya with Home Assistant and it works very well, reporting temperature to 0.1 degrees and humidity to 1% both every 5 minutes. Very easy to set up. Too early to report on battery life.

Very pleased with these sensors!

Arrived earlier than expected and I'm very pleased with the accuracy when compared alongside another monitor. Setting up with Smart Life and then pairing with Alexa was very easy. The only slight negative is that only %rh is displayed in the Alexa app not the temperature. However, if you ask Alexa the temperature she will tell you! Both %rh and temperature are displayed in Smart Life. Smart Life will also give a trend or history of %rh and temperature. I'm not sure about battery life yet, but if it disappoints I will edit this review. Summing up so far these sensors are great!Just a top up to my review 5 months later and battery level is still high confirming these are excellent value.

Far too sluggish

I had ordered them to automate heating within my home. They arrived quickly and are easy to set up with either Tuya or SmartLife app. They are also reasonably small. That’s where the positives end.The temperature was not exactly accurate but I could have tolerated that and adjusted for it. However, the updates to the app were far too slow and were lagging behind the real temperature too much. And as much as I tried the created automation was always a hit and miss and too unreliable. At one point the temperature in the room had exceeded the set upper temperature (where the heating was meant to be switched off) by four degrees and the heating was still on. They have been returned.

SIMPLE & EASY TO SET-UP FOR USE BY ALEXA

These sensors are small and easy to set-up using the Smart Life app. From there, Alexa automatically recognises them if your two apps are connected so you just need to add them to the appropriate group/room.I don’t use them for automation yet, but note that pre-configured ‘scenes’ on the Smart Life app require a paid subscription. Alexa’s do not. Another thing to be aware of is that the sensors don’t update that often (few times an hour) so wouldn’t be suitable where continuous monitoring is needed, such as heating controls.

Ok

Well it says it Tuya and works with Alexa, and for that I would have to say kind of.In respect of temperature yes it works with Alexa so that you can ask the temperature and it tells you. But while humidity is shown in the Alexa app, asking Alexa for it simply results in a message that this isn’t supported yet.It also does not supply a trigger for routines in Alexa based on temperature.So I say it works kind of and leave it at that.

Good for the price

It is small and light. not much bigger than my thumb and still contains 2 AAA batteries. It integrates well into the smartlife app which I already had running with other sensors attached. The app found the sensor as soon as it was switched on and paired immediately over WiFi. There is a Bluetooth option as well which would probably assist setup on a brand new install. It took a while before the temperature and humidity readings settled. At first was 3deg out but that was reduced to 1deg by the following morning. Interestingly the readings seen on the detailed reading history were almost spot on which implies that the headline readings are highly averaged. perhaps one an hour.
