Has anybody used one of these wifi thermometer/humidity digital units and placed one of the sensors under the house? While humidity is always a concern - it would be nice to know what the temp is down under - especially during the winter. I'm hoping I can find one that starts beeping if a low temperature threshold happens.

I've never had a water line freeze up - but I always 'worry' all the same. I understand some of the units have up to 3 channels so you can do inside, outside, and then down under. Pricing is ~ $25 (+additional sensors)

Don't see why it wouldn't work good. I have a 3 channel but only have 2 sensors for it. I have 1 outside and the other in my shop building which has heat and plumbing so I can check if it's cold I can see if the heat didn't come on.

I found one on Amazon that looks like it will work well - and it has a very good 4.5 star rating. It is 3 outdoor channels + indoor temp+humidity. The 3 outdoor channels will allow me to put one outside, one in my workshop, and put one under the house.

I'll update this post after installing and using for a week or two.

Ok...got the unit today and immediately set it up. It is literally just installing batteries and that's it. (NOTE: each sender uses 2 of the AAA's....so 6 total, and the receiver unit users 3 of the AAA's)(total of 9 batteries) FWIW - install the batteries in the senders first. Then the main unit. Give it a couple minutes and the senders will start reporting in.

Thermostat on the HVAC is at 74°. indoor temp on the unit is reading 73.6°.
The #1 sender unit is setting on my breakfast table and it shows 73.7°

I put a sender in the workshop (#2) and one down under (#3).

Workshop is showing 48.3°. Local remote weather station shows 46°.
The down under is showing 54°...and i have nothing to compare it to.

What's really nice about this is ALL of the info is showing on one device - ALL at the same time.

All told, unit +batteries, I spent ~$43. The data is such a relief. (Knowledge is power!)

Does it have min/max? The one I have does which will let you know just how cold it did get overnight.

have now had all of the sensors in place for a few weeks.

Sensor #1 is hanging right under the eve of the house.
Sensor #2 is hanging in the workshop
Sensor #3 is hanging about 1.5 ft in from the skirting (right under my kitchen at the water lines)

All three are reporting temps that are within 1° of the readings from other sources.

FWIW - one of the driving forces in putting these in place was to get away from leaving a faucet running so that a line doesn't freeze up. That's all good and fine - but with an electric water heater the water bill - AND the electric bill - were going up.
