Need recommendations on min max thermometer
 

I would like to put a min max digital thermometer in my GH. It would be great if it's wifi compatible. My GH is approx 30 yards from my house. Can anyone recommend a product or two. If you have personal experience with one that's even better.
Thanks....

I tried several "remote" thermometers in the GH, they tended to fail after 6 months or so. My GH does stay pretty damp, a really hostile environment for electronics. I ended up getting a wired thermocouple, the base unit is in the house. I run the thermocouple wire through a length of PVC pipe, to protect it from being stepped on. Unfortunately, the base unit doesn't do min-max, but over time, I found that if I checked it first thing in the morning, that was the time when temps are at minimum, max is afternoon.

If you can find a spot that stays drier, you likely won't have so much of a problem. 30 ft. for the remote depends on what else might be in the way (hope for clear line-of-sight) and what interference you might get from neighbors' electronics.

Govee sells several models on Amazon, but I have no idea of their longevity in a greenhouse environment, as Roberta mentioned.

If you are willing to cough up a few bucks, SensorPush is hard to beat.

I am using Govee, two of them, from last 4-5 months, bought from Amazon, seems to be working fine, can be monitored / compared temperature and humidity hourly/daily/ weekly basis from mobile app.
