Use your Raspberry Pi as a private chat server
Although the Diode App is a decentralized messaging / chat app that doesn't need a chat server, a Zone with just a few team members will often benefit from having a "Bot" as part of the Zone in order to relay encrypted messages to a team member who may have been offline when the message was originally sent.
You can make your Raspberry Pi into a Bot to ensure your chat messages are always delivered and your files are always available, no matter the online/offline state of one or all of the other team members. This creates a highly available collaboration tool that is fully "self custody."
To setup your Raspberry Pi as a Bot, follow these simple instructions:
1) Install the Diode App on the Raspberry Pi
2) Invite your Raspberry Pi to your Zone
3) Change the role of your Raspberry Pi to a Bot
