F007TH

Purchased an additional sensor for our WS-10, as I was moving one between rooms on a regular basis. Had a bit of a problem with the setup, and even though I got it done (took about 5 minutes), I emailed tech support to ensure I did it correctly, and subtlety suggested they should include adding units to the manual by asking where in the manual it was. Emailed late Saturday, and had a response Sunday morning, even though support is only supposed to be available M-F. Very impressive. Ed confirmed that my method of adding the new sensor was fine, and provided a link to the manual and let me know more information was in part 5.5. To my embarrassment, the information was there, I had just read right past it. I'll likely be adding a couple more sensors in the next couple of weeks. Great product, works as described. Some of the best tech support I've experienced in MANY years.

Synched immediately, when the correct channel was selected. Batteries seem to last for over 6 months. NOT waterproof!! Can get damp, but will not survive direct immersion, of laying on ground during a rainstorm. This was a replacement for one which fell off a window ledge, onto the bare ground, and got drenched. This one is sitting in between the screen and window, gets wet, and still works fine. I'd say the readings are accurate, at least compared with others of the same make.

Suddenly my sensor after maybe 4 years drifted up 5 f. So now got this replacement. No instructions in box, drove me crazy trying to setup, then found my manual. Power sensor then power monitor ! New sensor working fine. Surprised because usually the humidity part dies first on most weather stuff.

Easy to set into working with existing monitor.

I bought 4 (weather station) sensors & 2 consoles 4 years ago; sensors outside front & back of house, sensor upstairs in the bedroom & downstairs in the den; console in bedroom & den. I've changed batteries from time to time & they continue to start back up just fine. Recently when I retrieved one that wasn't transmitting, I found a battery had leaked inside, essentially killing it. So I ordered a replacement sensor. It showed 20 degrees more than it should've. I did a Return/Replace, the replacement was doing the same thing. I tried again.Update 7/10/25: Fortunately, the 3rd sensor I received shows accurate temperature & it only took a few minutes for the consoles to recognize the new sensor. The original sensors & consoles continue to work good with the exception of the sensor my leaky battery killed. Alexa can tell me the temperature outside, but I especially like knowing that my bedroom is cool enough (portable A/C & fan) before I go up to bed. It's also interesting to see the major temperature difference between the shaded one on the back deck & the one on the sunny front porch.

Works fine. It replaced older one that quit after a few years.

Didn't last a year. This was a replacement for a ten year old sensor. It didn't even last a year!! Obviously the quality must have gone way down. I am sceptical about purchasing another one. Oh, and btw, it's been in a shielded area from the weather. It reads 130 degrees.

I was pleasantly surprised that these units are still sold for my base unit. On of my senders went inaccurate and this fixed it!

Have the main bar station, these are additional sensors to distribute in my humidifier to control humidity and temperature

Works as advertised. when calibrating, all sensors were within 2% and 1 degree. Alarm function is hit and miss - alarms randomly going off during the night.

Second additional purchase. Expensive and unreliable. Buy Something else.
