I have a 5 in 1 pro weather station (model 2064). I am currently using my laptop to send data to Wundergound. I have an LG tablet that can accept a full/standard USB connector. It would be easier for me to have the tablet running and transmitting than my LT. IS that a possibility?
I don't know of anything that is written for Android tablets.
There are programs you can run on things like a Raspberry Pi, though, that will send data to wunderground (e.g. weewx). If you can get Linux running on a piece of hardware, there's a good chance you might get weewx running on it, too.
At this time you cannot use a tablet to transfer data to Weather Underground. This has to be done from a computer. We would recommend using the smartHUB if this is not convenient for you. We see you have already looked into this option but, have added a link below for your convenience. Please let us know if you have any other questions. Thank you and have a great day!
