I use Aqara for temp and humidity. Just make sure they are either talking directly with the hub or via a repeater that works with them - Ikea works well, I've read that XBee's work well too. I mainly have Ikea Tradfri repeaters, I moved ST outlet repeaters to areas where I have no Aqara's.
Nyce motion humidity sensor works, Iris 3rd generation motion...
For the zooz, I had to set both humidity and temperature to the minimum level change to get the humidity to report. That ate the battery quickly.
Do these report humidity when motion is active, because the zooz does not no matter what level change I have the driver set to?
Mine did, but I don't have them anymore due to the battery not paying very long.
I love my Iris v3.
What's the model # for those I have the v2's

I too am using a Xiaomi Aqara Temp/Humidity/Pressure sensors. I'm not big on recommending it, becuase it does fall off every so often now, even though there's a Trådfri outlet right next to it.
[Edit] Sorry I didn't notice before that I had linked to the wrong device. Looks like the ST814 is not longer available.
For dedicated sensors that are on the compatible devices list, you can still get the Everspring Z-Wave sensor.
Xiaomi aqara here too. They were enough cheaper versus the next best supported alternative that the cost difference paid for the dedicated hub I put them on...
Bought a batch of 15 for $11/ea shipped off of banggood on some sale.
There is this untested device that seems to be European in origin. Perhaps you'd like to be a forum Guinea pig? 
Not for that price. Having my bathroom exhaust fan automatically come on isn't worth an $80 cost

Maybe just forget the smarts then?
You already have a smart switch on the fan? I wanted to keep our Leviton timer in place for mine, because the family was used to it. But my daughter (now no longer living at home) was the only one steaming up the bathroom. I've got one left, but he's a ways from hitting puberty, so at the moment it's not an issue, but it will be I'm sure.
Delivered, my cost for the Insteon micro module I chose to use was $67.30 CAD and the Xiaomi Temp, Humidity, Barometric pressure sensor was $15.83 CAD. So I paid $83.13 ($63.80 USD), plus the cost of a water proof box, and my time getting up in the terrible attic space to install the micro on/off module in crappy low light conditions, balancing on rafters so I didn't fall through the ceiling. Plus I have to relink the Xiaomi every so often. In addition, I bought a Tradfri outlet which was doing more at the time, but really is only serving that sensor now (and not really doing that great of a job for some reason). That was $16.95 CAD additional.
I would probably go with the Panasonic dumb sensor I listed above if I were to do it over.
Right now it cost me $25 for a Lutron Dimmer switch (I know they say not to use dimmers on fans, but it works fine) and I have a $12 Iris V3 Motion/Temp/Humidity sensor ordered this morning on the way to try out for the humidity measurement.
Hmmm, $25 USD for a burned out Lutron Dimmer and around $75-$250 USD for a burned out bathroom exhaust fan?
@JDRoberts posted on this some years ago. All still valid info.
Lutron dimmers don't support Fast ON like Insteon do as far as I understand. I had an Insteon dimming micro module available, so I could have just set it to use Fast ON, but rather than risk my $300 inline bathroom fan, I ordered the ON/OFF version. Just wasn't worth the risk. Something to consider.
The current fan in there has been there since 1983, so if it "burns out" it's due for an upgrade anyway.
"IF" it does burn out, then I will replace it with the On/Off version but for the Lutron no neutral On/Off switch the cheapest I found was like $60. So I'm taking my chances, and will replace if necessary.

Ah, the no-neutral problem. I didn't realize you were up against that too.

How do you like the Iris V3? Trying to increase my reporting. Have nyce and zooz 4in1 I'm there now.
It's working fine, usually reporting humidity changes within a 5 minute window. Works much better than my Zooz 4-1 which only seemed to report humidity if no motion was present.
I have lutron caseta switches in my bathroom. I have the Aeotec multisensor 6 that does motion and humidity in this space. My bathroom isn't overly large, and I use an iris motion sensor up in the corner above the door to detect motion coming into the bathroom to turn on the lights over the vanity. I positioned the multisensor in the ceiling with the ceiling mount between inside and outside the shower. I only use motion sensing on this device when someone is inside the shower with the curtain closed. It keeps the lights on while someone is inside the shower so the lights down turn off from no motion detected from the iris sensor. In any event, the humidity increase will turn the fan on every time after the shower starts and will automatically turn the fan off once humidity reaches the same threshold it was before it turned it on. Using cSteeles driver and power it via POE that I ran through the attic on cat5e cable so it has fast reporting and I don't have to replace batteries. Best solution for me.
Have been thinking of late that I may replace the Xiaomi humidity sensor in my bathroom that I have to re-pair every two weeks or so, with another Ecowitt sensor that connects to my Ambient Weather station. The driver that I’m using, created by @snell, works perfectly. Because it’s a proprietary frequency, connected end to end, these sensors never drop, their range is good, and I’m already using one as the comparison humidity to the Xiaomi, so I know their values are easily read into HE. My weather station software supports more than one humidity sensor, and so does @snell ‘s driver. For $12 my problem can be solved once and for all, plus I’ll have a little display on it that tells me what the current relative humidity is in the bathroom.
