Hum.... i need a little bit more portability. Thanks.
Any other suggestion anyone?

The Konke temperature and humidity sensor works well with Hubitat - no special repeaters needed. However, it is restricted to zigbee channels 15, 20, and 25.
With a cell phone charger, you can plug it in anywhere. I wasn't really clear on that point. Unless you're looking for battery powered. Then yah ... there's that.
@Guytas, I play around with my sensors and others that has temperature an humidity measurement as well. It turn out that in monitoring room temperature and humidity, the placement of the sensor is much more flexible compared to where you have to place a motion sensor. Obviously, contact sensor need to be place at specific location.
I do not want to hijack this thread by adding too much specific information about my sensor here. But, if you like to talk more about it, please feel free to PM me. In any case, I and many of the community member will help you regardless your choice.
I've had 3 Aquara Temp/Humidigy/Pressure sensors for almost a year. I've had absolutely no issues with them. I don't have many Zigbee devices so my Zigbee network is very small, or at least not well populated.
I love Iharyadi's board and found it to be very stable. But I must say I am disappointed in the performance of the on board BME280 sensor. In my arduino experience it was always very accurate without any offsets needed. The iharyadi board I have requires significant offset for the temperature.
Ho they are probably very good sensors @iharyadi but we do have green houses and when my wife prepare the plants, she keeps moving them in and out almost every day. We have right now the WirelessTag sitting on one of the shelf on each moving tray shelves. I cannot imagine unplugging all of that, and using extension cords... No, it is easier for me a portable one. Thanks anyway.
I've used the Konke sensors for about 7 months with Hubitat. They work flawlessly. Bought them for about $10 each on AliExpress. They're about $15 on amazon.com
I have to agree with @JohnRob with the fact that these sensors also for me have been very solid. And with the newly developed driver by @markus, I'm guessing that these will be even more reliable. This due to the fact that all Xiaomi/Aqara devices with new drivers seem to connect and replace the repeaters in a more correct and efficient way according to the findings from @aaiyar, that even I can confirm.
The Aqara temp/pressure/humidity sensor are definitely stable IF you have a carefully laid out Zigbee mesh AND you don't use any incompatible repeaters, and definatley NO Zigbee lightbulbs on the same Zigbee mesh (Sengled are the exception). They won't mess with your mesh because they're end devices, but they will certainly drop if you don't have the position of the repeaters just right (definitely trial and error) and they also will drop as they start to approach 50% battery (which granted is several months). I had mine performing perfectly for months. Moved one repeater to an outlet just 4 feet closer to the hub and it began to drop regularly. Moved the repeater back to its original location and the stability returned.
I have only one of the Aqara temp/pressure/humidity sensors, but I have Aqara leak sensors and one remaining Mijia motion sensor still directly paired. Only the temp/pressure/humidity sensor ever drops and it's only when the battery nears 50%.
However, if your greenhouse isn't attached to your house (e.g. You need to get that signal to travel more than 30 feet open air from either the hub to from the last powered repeater, and you need a few of them, I'd tend to agree with @aaiyar's recommendation for the Konke. The guys that have them say they are very solid.
It's going to be a lot less restrictive to set your Zigbee radio to channel 15 or 20 and use the Konke then it is going be, having to use ONLY Xiaomi compatible repeaters like I have to (I'm using three IKEA Trådfri repeaters - Two outlets and one dedicated repeater). I understand the need for portability and battery power in a greenhouse, but if you have a situation that you can use one of @iharyadi temp/pressure/humidity/luminance sensors, those are excellent. I'm using one as the reference humidity for my Xiaomi Aqara temp/pressure/humidity sensor in my bathroom, so that the exhaust fan turns on automatically when someone is in the shower, but still takes the sticky summers we have here in Toronto into account.
I wouldn't ever buy the Xiaomi Aqara or Xiaomi Mijia devices from Amazon unless the price was much better than you're seeing. I have always bought from either Bangood or Gearbest. During non-pandemic times, I have chosen the Canada Priority Line delivery option for just a few bucks. I almost aways received them within two weeks. Right now, don't know what you'll get. Some buy from AliExpress too, but I personally don't like using them because they don't take PayPal. Since you're in Canada delivery is going to be a problem from China and Hong Kong right now.
Ouch! $53 CAD to get them from Amazon.com right now.
That's why ya buy them from China and not Amazon....
Right. But the pandemic has caused Canada Post to reject at least speedpak items from China and Hong Kong right now. He's in Quebec, so the options are more limited than US buyers.
You need a friend in the US you can visit periodically. I have amazon prime and for me they are $15.99 + state tax (~7%)
Also I have no love or hate for the Aquara. I bought them a while ago from banggood (or gearbest) when they were on special. I think they were about $10 each.
I go to Quebec often, they are limited on many things - including signs in English.
har har har That was a joke in case it wasn't clear. Quebec is a great place to visit (between April and October).
The last batch of 12 Konke temp/humidity sensors I bought, I got for $11/ea including shipping from AliExpress.
I have my parents in Oregon (no tax), and siblings in California, but the cost gets to be close to the same after shipping from there to here. I've stopped sending stuff to my parents because I don't know when I'm going to be able to get there again at this point in time.
If you're not adverse to a wait and giving your credit card to AliExpress, then it's probably the best option right now.
@Guytas I've been told they're not that fast at responding, but probably good enough for your use. Centralite are another option and generally good devices that don't need specific repeaters either. Aartech is in Oshawa Ontario, but they will ship free if the order is over $100 and you said you need a few. Maybe you need something else they sell?
@Guytas I just remember this local community integration someone pointed out. It's not such a bad price either. The gateway and one sensor is just $58 CAD (with a coupon) and additional sensors are $22 CAD. What's nice about this option for your case is you can also get the plant moisture sensors. The low frequencies these sensor use will travel very far and you won't have the issue that a remote building might have with Zigbee 2.4 GHz frequencies during heavy snow fall.
Yes I think this sounds like the best option. HE is compatible to signee 3.0 I assumed. I didn’t check that yet. Cause yes 56$ for 4 sounds cheap if they are any good.
Reading all the comments is getting confusing, but I appreciate every one of them. Thanks all.
Yah, I guess in Texas you don’t need winter coats. but winter is very nice too (as long as you don’t have to do snow removal.
Actually, it is the other way about. Zigbee 3.0 is backwards compatible with ZHA1.2. So the Konke sensors will pair to HE using ZHA1.2.
I have 8 of them. I think @JasonJoel may have more. They work fine as long as your zigbee channel (on Hubitat) is set to 15, 20, or 25.
