Ambient Weather WS-3000-X5 Thermo-Hygrometer Wireless Monitor w/ 5 Remote Sensors - Logging, Graphing, Alarming, Radio Controlled Clock

My house is on three floors but I live primarily on the middle floor. I may not go upstairs for weeks. On the ground floor, if I forget to shut the garage doors, they might stay open all night. Keeping up with temperatures around the house allows me to keep up with left open doors to the outside or a heat pump that has died on me. I used three different digital temperature modules for this. The screens on all of them had faded over time so I needed something better. Today that arrived.When I first unpacked it, I was a little surprised at how small the central module was: really, my iPhone is bigger. Still, I had read several comments speaking of how easy this was to read. They were right. It is VERY easy to read.No more clutter on my dresser from the three screens (one large, two small). Now I have one small screen on my dressor and I can easily read it from my recliner (I watch TV in my bedroom). Each sensor has its own screen showing the temperature and humidity. I have all of them hanging freely rather than being velcroed/command stripped/screwed to the wall. The accuracy of the reading is better without the direct contact.Setup was a little bit of a challenge though I finally figured it out. What gave me the most trouble was assigning a label to each sensor so I knew where each channel represented. I looked through the questions and answers here on Amazon, and some even said it couldn't be done. Well, that's not true, because I just did it. The main bug in labeling is that there is a limited number of names that can be chosen from. For example, I was able to choose "Master", "Outdoor" and "Attic", I was unable to find a "Garage" or "Guest". Hopefully some future firmware will allow one to edit the choices rather than just select from a limited list of possibilities.Those are my initial thoughts on this product. If I never come back to update them, you can safely assume it has held up for me. OTOH, if anything causes me to reevaluate, I will come back to update as well. Posted 5/22/2023

I got this 5 sensor system to replace an older, cheaper setup from a different manufacturer that was acting up on me. This beauty came pretty much calibrated out of the box, but I love that if a sensor were to regularly drift, I could try re-calibrating it. The screen is very bright and visible from several feet away (which I love). The graphs give me some really great visual history that is helpful for me. I have sensors upstairs, downstairs, in a room with a lot of electronics, outdoors, and inside a hobbyist greenhouse. I can see at a glance on the graph exactly how much hotter the greenhouse gets than the outdoors on sunny days, what time of day would be best to activate a misting system to cool down that greenhouse, and how long it takes for the misting system to lower the temp and/or raise the humidity to match outdoors or beyond. I can even see how long it takes after the misting system has been turned off before the greenhouse starts to heat back up again and/or reach an unacceptable temp again. That's the primary reason I purchased it, but it's also great to see how hot or humid rooms in the house are and the general weather outside... and I can take a sensor anywhere in range if I need to know if the attic is too hot or what not.But, back to the general use. I am a bit disheartened that the screen doesn't have any noticeable mount points for mounting to a wall or even a way to attach magnets to stick it to a refrigerator. The base is small and flat, but the screen is tilted at an angle, so it's meant to rest on a flat surface like a desk or shelf, but being able to mount it somewhere on a wall by a thermostat or a doorway would have been nice.It does flash really bright for a second when it's first plugged in, and that made me wonder if it was defective or if I was harming it when I had to unplug and plug it back in multiple times while moving it around to find the perfect spot for it. I think the graph re-started on resets, too. I'm sure if you have a memory card, it'll keep the data, but the actual graph may reset on a power outage - don't know if it does that when a card is installed.I did have a slight issue with placement. I noticed that if I put my screen in my laundry room, 2 sensors that were outdoors and in the greenhouse would drop out every so often. I hadn't had that issue with my older setup, but these use a higher frequency. I assume that there were just too many walls, pipes, and air ducts blocking the way for a proper signal. Moving the screen closer to an exterior wall resolved the issue.I love this unit. I may even buy the 3-sensor unit to have 2 screens and 8 sensors since they're all compatible. I saw where instead of a graph, the firmware could be flashed to show all 8 sensors instead of a graph, but I'd love it if I could program 1 to have just the graph and the second to have just the real-time numbers.
