The snowy weather here on Vancouver Island has given me some unexpected time to work on this. I now have a working template file and python script that will produce and post weewx data to a Mastodon account. Just setup an account on your favourite Mastodon server, mark it as a bot, create an API/Client Key (under development in your account's preferences) install the template file to one of your skins (I just added it to the Standard skin. put the python file somewhere it can be run with cron run the python file with a command like this:
sudo python3 weewx_to_mastodon.py --server https://mstdn.ca --wxdata https://mywebpage.com/mastodon.json --api_key biglongstring234fssdf I've attached my working files if anyone is itching to have it, excuse the messy code but it should be fairly self explanatory. You should only really need to modify the values in the json.tmpl file.
