***THIS APP IS BEING DISCONTINUED. PLEASE READ BELOW*** On January 31st, 2023, the AmbientTool App will be discontinued. The AmbientTool App allows you to connect the Ambient Weather WS-2902 Weather Station Console, versions sold from December 2016 to May 2018, to your Wi-Fi router and the internet during the initial setup. If your WS-2902 console disconnects from Wi-Fi for any reason and needs to be reconnected after the app discontinuation date of 01/31/2023, you will no longer be able to reconnect your console to the Ambient Weather Network (AWN). This does NOT affect any WS-2902A, WS-2902B, and WS-2902C consoles purchased AFTER May 2018. These consoles utilize the Awnet App for the setup process. Moving forward, the WS-2902D will no longer require an app for internet connectivity, allowing any user to connect using an internet browser. If you own one of the affected consoles, it will continue to work until you have to update any Wi-Fi settings; this may include a firmware update or after resetting your console. Once the AmbientTool App is sunset and you need to perform one of the above activities, your console will still showcase your weather station readings. However, the console will stop reporting your personal weather station dashboard information to AWN, including data collection and tracking. To maintain a connection to AWN, you will need to upgrade to the Ambient Weather WS-2902D Console BEFORE January 31st, 2023. To purchase a a replacement console through the AmbientTool Upgrade Program click here: https://ambientweather.com/ws-2902d-c-ambienttool. Ambient Weather is offering a limited-time discount for those affected by this app discontinuation. You will be eligible for a $35 console rebate through the end of 2022.
