The bot requires approval (whitelisting) from your moderators/admins, not mine. LiveThreadBot will work for any community federated with lemmy.world. Alternatively you can very easily run your own instance of the bot.
Would it be possible to do up to a day early? Cuz we tend to have pre-match threads so people can discuss like lineups and what they expect and stuff; just not sure if that might be a bit server intensive if it updates live.
You can change how long before kickoff the bot will post a live thread with the command demonstrated with the Bot Maintainer account. The time input is in seconds.
Only mods/admins can change it for a community.
In regards to live updates, the bot checks for messages once every minute. It updates the live threads every 30 seconds, however I've changed it so that it only updates every 10 minutes until 30 minutes before kickoff. Just to spare ESPN from being needlessly spammed.
