Review: Don't buy more than one unit w/3 remotes - Addendum to original: After posting 2 star rating below, out of the blue I received a full refund offer from the manufacturer followed by a full refund. Mind blown and to be fair, I need to set the record straight if I didn't do a good job below. My only issue is with owning 2 units and having both flipping to the strongest remotes w/o interaction from me. A single unit with 3 remotes works great and the price is right. Temperatures have been accurate (within 1/2 degree) between the 3 remotes and the onboard temp reading. Bottom line, the item is great, however adding a 2nd unit with additional remotes, not so much! BTW, I'm having no issue receiving signals through refrigerator and freezer doors (1 upstairs, 1 downstairs). I'm impressed, only good companies do what this one did in offering an unsolicited refund! Original 2 star review: I have two of these in my home for a total of 6 remotes. Before I purchased them I asked the question: Looking for specific info? "can I use 2 of these with 6 remotes" Alexa is generating a response... Yes, you can use 2 of these with 6 sensors total! Based on the product's own setup guide and community Q&A, here's how: Setup for 2 bases with 6 sensors: Remove all batteries from both base units Install batteries in the first set of 3 sensors (channels 1, 2, 3), then power on base unit 1 — wait 3 minutes to let them pair Install batteries in the second set of 3 sensors (channels 1, 2, 3), then power on base unit 2 — wait 3 minutes Important notes: Each base unit only displays its own paired 3 sensors Keep the two base units separated by some distance to avoid cross-talk between sensors, since all units use the same 3 channels If a sensor pairs to the wrong base, you can manually re-pair it using the TX button on the sensor and the CH button on the base Several customers have confirmed this setup works well for monitoring multiple locations like garages, basements, greenhouses, and outdoors. I am constantly having to re-pair these units. They are accurate, signals transmit a long distance, even thru refrigerator doors, but they cross over about every two days. As you can see by the pic, 1 and 3 are exactly the same unit. If only buying 1 unit with 3 remotes, go for it, it's great, but don't do 2 units, you won't be happy.
Review: Straightforward to install and use - This Thermometer / Hygrometer is working extremely well. I've only had it a week, but it was easy to set up (I had to get batteries) and install. I currently have one remote sensor unit outside, one in the garage and one in the attic/roof space. They are reporting without drama and the base unit is getting the kitchen temperature consistently and reliably. I have the remotes hanging on screws I put into wood in suitable places and they seem to be on very firmly. The central unit is sitting on a counter top with the stand holding it steady, but I will hook it onto a screw into the wall when I get a chance. This will also move it from the kettle, which influences its temperature! I have the central unit plugged into a USB-A charger and it is keeping the display bright and very easily readable (I also have batteries in it in case of a power outage). The remote units are small and not in the way, and the central unit will be easy to place on the wall and out of harm's way. I have had similar units from long ago in my previous house. This is a far nicer unit, was easier to set up, and allowed me to run 3 external problems, plus the central unit, which is really good. I am very happy with this unit and I hope that all I have to do with it over many years is to change the batteries.
