why do you think they’re off?
email the company - they get back pretty quickly.
somewhat dumb question - how cold is too cold for a wine cellar? my philly cellar is passive during the winter and it’s just under 50F now with decent humidity. should i care?
I think they may be off because I see big swings in humidity (e.g. from 43% to 65% in less then an hour) on certain tags where there’s no external activity.
look at your charts over several days or a week. i see pretty significant humidity swings as well, but it fits a very consistent pattern.
I definitely see a consistent swing, but that level of change doesn’t
a) seem normal unless someone were opening up the door or otherwise changing the environment
b) seem like it would be “healthy” for wine storage
p.s. this shift in RH is not concurrent with a shift in temp which stays literally within 1 degree the whole day while other zones see wider shifts in temp and little change in RH.
yeah, i see 5% - 8% RH swings over the course of a day. can you test against another tag? if not, you’ll likely need a replacement.
I know mine were off when I got them because I have 7 of them (I started using them around the house to track temperature changes and differentials), and when I put them all side by side in a room, the readings were all over the place. I have an Air Thermapen that’s supposedly NIST traceable calibrated, which I used to calibrate the temperatures. But they also seem to have a somewhat non-linear response, because if I calibrate them all to match at room temperature, they often still won’t match at warmer or colder temperatures. No idea what to do about calibrating humidity.
At this point, I see these as a fun toy, and a reasonable way to monitor things going way off track (e.g. cooling unit failing), but I don’t really trust them for precise measurement. But I’m also not that worried about it (I don’t think a degree or three difference is going to be disastrous).
A little late to this thread… My existing solution is from a friends startup and the HW I am using was deprecated so I ordered a wireless tag system and will give it a try… seems very nice…
anyone try the alexa integration or nest integration?
Not I. I have both Alexa and Nest, but I wasn’t clear what I’d want them to do if integrated…
Netamo has been amazing
They give examples here…
dunno if you can query temp, humdity or motion sensors… will have to play with mine when it arrives…

I have Lacrosse, Netatmo and a really cheap wireless tag that really give me good information. With this kind of coverage, I have been able to keep up with my few failures of my system. The only problem comes if my internet goes down. I think I have paid a total of $200 for all three. Well worth it for the amount of wine at risk.
I recently moved, built a new cellar and was researching options for cellar monitoring. I wanted something robust with hopefully free or at least low cost monitoring. I was a cellarsensor customer before they went under. Most other solutions always seemed not so robust or very expensive. I ran across this during my research:
I have had it up and running for months and I am extremely satisfied. It is a self contained unit that logs to the cloud for free as long as you have 2 or fewer units running. Furthermore it appears this is the company that made the hardware for the cellarsensor products.
In any case, it is pretty inexpensive. $99 for temp only, $160 for temp and humidity and zero ongoing costs. The initial setup requires a PC. Once it is set up it communicates direct to the cloud through your wifi network. If it loses wifi connection it continues to log and monitor on its own. Once wifi is restored it uploads the data to the cloud. You can graph, set up alarms, etc via the web. It can alert you via email if your cellar falls out of the perimeters that you set up or if the unit loses connection or has a low battery. The unit can be plugged in or runs for months on the internal battery. I highly recommend this and just wanted to share with others out there in a similar situation. It is very well constructed and they make tools for pro chefs/restaurants.
I am not affiliated with these guys, I have no horse in this race… just sharing my experience. I started with a Netatmo but prefer this unit for the build quality, robust interface, quality logging, and no need for a base station.
Mike,
The device you are using now is made by Lascar, a UK Company. The Cellarsensor hardware was made by T&D, a Japanese Company. Disclosure, I sell both of these products. These are both general purpose data loggers used in a wide variety of industrial applications. Certainly not hobbyist level products and both very functional. I am not sure if the Cellarsensor stuff was anything more than re-badged with their name. T&D provides a free cloud service that is not limited to the number of sensors used. I suspect that the Cellarsensor hardware just needs to be re-configured to point to the T&D cloud service and it would be fully functional. It just wouldn’t have any wine related branding 
Pete,
Thanks! It figures I would get this answer… I threw all my cellarsensor stuff out a just couple months back figuring it was no longer functional.
Thanks for the clarification too. I saw all these products on the thermoworks site and assumed they (thermoworks) made them all. Upon closer inspection I see that you are very much correct. I saw this stuff:
http://www.thermoworks.com/Data-Logging/series/TandD
It does indeed look like cellersensor just re-branded them.
All that said, for a hobbyist perspective I like the Lascar product (EasyLog TW-WiFi-TH)) as it is just a single unit connected direct via wifi. The T&D unit had sensors with non rechargeable batteries and a much higher price.
In any case, your point agrees with mine. These are professional level products and the Lascar unit is not much more money than the consumer focused products mentioned above in the post by others.
i use which I like the one on amazon that’s $9.99 i just wish i didn’t have to open it to check …I’m sure there are many more $$ that can shoot your phone the #
Put them in a room alone and before you know it: baby monitors! 
So the wireless tag arrived last week and I finally got around to installing it.
First regular tag was easy and all is well and it works fine. Software seems quite powerful with lots of connectivity options for interacting with it. My one challenge so far is with the PIR Kumo sensor. The other sensor came with some tape you pull off the battery and it starts flashing and then you pair it to the Tag Manager. The Kumo sensor came with the coin battery already installed and no insulative tape. I have been unable to get the PIR Kumo sensor to flash or pair with the tag manager. Even popped it apart and remove battery for a minute and then re-installed it with no luck. Anyone have any insight on how to get this PIR Kumo sensor to pair.
Still playing but seems like a very cool product. Certainly could be used in home automation and security in addition to our Wine Cellar temperature monitoring applications…

A Little more digging on the website versus the app and I found this…
very clever. works fine now…
Sean
been playing around with the motion sensors and IFTTT integration with Hue lights (which i’m now obsessed with). all very easy to set up. for example, certain rooms are armed to turn on when someone walks in, but only when there’s not enough ambient light to light the room. and then they turn off automatically if there isn’t motion for x amount of time.
i got a few of the kumo IR sensors which monitor temp and humidity as well. https://goo.gl/3fYwoU
Which Netatmo model are people buying for a wine cellar? Do they have one available that is batter powered? There seems to be limited information/reviews on Amazon about this, thanks!
