AcuRiteAcuRite Atlas Professional Weather Station with Direct-to-Wi-Fi HD Display, Lightning Detection, Built-In Barometer, and Temperature, Humidity, Wind Speed/Direction and Rainfall Measurements (01001M)

I've had Acurite products for close to 20 years. My tabletop forecasters still work and had to replace outside sensor once. I wasn't completely happy with the 5 in 1 device. After multiple support sessions we were never able to connect it to the PC, App or Weather Underground. I used it as a stand-alone and it was fine. After more than a decade on the roof, the Anemometer and Hygrometer had enough and quit. I researched the Atlas device and purchased it as a replacement. At first, I had difficulty connecting it through the PC as recommended. After activating the Wi-Fi on the display unit, I used my Android phone to connect to its Wi-Fi. I entered the IP Address on a browser in my phone and the connection page popped up. Completed page and reconnected to my home Wi-Fi. Voila! Atlas connected to Display, PC App, Phone and Tablets. I would give this device 5 Stars except for the Indoor Temperature and Humidity data does not appear on MyAcurite App. I was expecting that information for when I was away.Update 6/04/2023. Worked great for 3 days and went offline. Wi-Fi full strength, battery level full. No signal from sensor. Nothing was changed or moved. See what support says tomorrow.Update 6/6/2023. Support responded promptly. Replaced brand new lithium batteries with brand new Duracells. Sensor came back online. For 28 hours and went offline. Followed Factory Reset instructions if sensor went offline again. Another set of brand new batteries and reset system. So far so good. If it goes offline again, it's going back.Update 9/07/2023 Customer Support deemed the sensor unit faulty in June because it would drop out and the red light would stop blinking. I had to wait until mid-July until remediated sensors were available, and they sent me a replacement. So far, so good. Had a fluctuating signal strength issue but that was resolved by moving the display unit to a different location. Because of Customer Support, I bumped it up to 5 stars. I'll buy their products again.

Final Update: I would advise to steer clear of this junk. After back and forth with Acurite support, they ended up sending me a new weather station which they said they had tested. The original weather station was reporting the same UV level all day, even into the night, so it was broken somehow. But the main problem continues to be the horrendous display unit. I cannot get the display unit to reliably connect to wifi. Acurite uses a ridiculous antiquated method for Wi-Fi connection. It's hit or miss getting through the initial setup, but if you do manage to get through initial setup, you're then frustrated by it losing connection constantly.I bought this until to try and build weather data over time, and you need connection to WiFi and Weather Underground to do that. This unit fails spectacularly on both counts.Original review: As others have noted, the WiFi display unit has poor connectivity. For me, it has dropped signal about five times in the last three months. When it drops signal, it does not automatically reconnect. You have to manually restart the unit, then it will reconnect. There is no explanation for why it drops the signal. I have not noticed any pattern to it, and my WiFi itself has not had any issues during these periods. When it drops signal, it stops reporting to Weather Underground.The odd thing is that I will get an email that says the display unit lost signal from the sensor. But that's not the signal that dropped. I have never lost signal from the sensor to the display unit, only from the display unit to WiFi. So, their error reporting is not even accurate.The display unit is using ancient technology all over. Almost all the components are dated from 15+ years ago. It uses a micro-USB power adapter when virtually all similar electronics these days are powered with USB-C (even cheap little imported electronics). The screen is using an ancient LED panel that has low resolution, low brightness, poor viewing angles, and uses TFT technology instead of IPS. I've had tablets from ten years ago with vastly better screens. It is not a touchscreen, but uses three capacitive buttons below the screen for selection. These buttons are finicky and don't always register touches. This is supposed to be Acurite's top of the line product. Pathetic.The process to set up WiFi requires you to use another computer to connect to its own network, then log into the IP address of the display unit and input the WiFi credentials of the network you want to connect it to. It uses only 2.4 GHz, so you cannot connect it to any modern router that intelligently uses both 2.4 and 5.0 GHz. This is technology straight out of the 2000s. Nest thermostats have been around for 14 years and used more modern WiFi connectivity than this piece of junk. The downside to using this ancient technology is that it doesn't play nice with newer routers and it isn't nearly as reliable. I did set up a dedicated 2.4 GHz network on my router to connect to the display unit, but most people have no idea how to do that.Acurite sourced these units at a STEEP discount. The entire display unit probably cost $5-10 to make, and they charge $100 retail. Just maintaining support for buyers who have trouble with the WiFi connectivity costs way more than what they're saving on upgrading the units to use modern technology. I reported to them that my display unit had connectivity troubles and they replaced it under warranty. However, it's been replaced with the same unit. I'm counting down the days to the next WiFi signal issue.Update: having the same exact troubles with the replacement display unit as well. It doesn't even broadcast a network to connect to half the time when trying to set it up, and it drops the network just as you're trying to save the settings. I have yet to get it to connect to my Weather Underground account. Of course, I am well past the Amazon return date, so I'm probably out of luck with any recourse. I wish I had never purchased this.

Bought for my husband after Hurricane Helene took out his original one in the flood. It works well and I added the lightning strike detector and back up power pack. He loves it other than the inside screen. He likes the set up on the original one...it works great and he is getting use to the new screen set up. And he likes the connection with the app also.
