I had a problem uploading to CWOP using this logger. Firmware 1.17, discussed below, helped fix this problem, as well as some direction from the developer, Wojtek. Now uploads to CWOP, Mesowest, pwsweather.com and Weather Underground all work perfectly. A great product and a perfect supplement to my hardware setup I was looking for—uploads to weather sites without using a computer.
All new products, particularly those that are technology-based, like this logger, will have issues (i.e., bugs) that will take awhile to identify and fix. This device, released in early June 2018, will be no different. So if you have issues or questions, contact Wojtek, who, based on my experience, will do his best to resolve on a timely basis.
