WiFi Hygrometer Thermometer Sensor: Smart Temperature Humidity Monitor, with Remote Monitor and TUYA APP Notification Alert, High Precision Indoor Thermometer No Hub Required, Work with Alexa (2-Pack)

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 🤷‍♂️

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.

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.

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.

Im constantly bombarded with low battery notifications even though ive changed them 3 times this month. The battery doesn't transmit data half the time, and when it does its 4 degrees lower than the other thermometer I have plugged in next to it. I very much regret wasting money on this item...

Good worth the money easy connection to app

It works, but its not very instant, and the recording / logs is like every hour on the graph, yet temperature can go up slightly or down in that time, but IMO it would be better if it was more responsive or you could adjust the timinig, other than that it is good, but need to get something to compare it with.

I think these are good for the price. They do tend to eat batteries a bit. I use lithium batteries for ones outside because cold wrecks batteries. Really if you want something that consumes less power you need the gateway ones. The temp is reasonably accurate. My belief is that on the All devices screen they update the temperature every time it changes by 0.5 degrees, although this isn't entirely clear. On the graph they update once per hour so this is not rapid monitoring presumably because if they updated faster they would eat batteries even more. They are easy to set up but one word of warning do not try to set up with a VPN activated - they will not work. Suspend the VPN and they will register. They will work with vpns once registered though.
