I am wondering if there is a chat program that works locally when the internet is out but still be connected to from the internet. I know this will be something that is self hosted.

Bonus points if I can set it up on the raspberry pi that is running Home Assistant.

    Briar works completely offline as well as online and has Android apps. I believe iOS apps are coming soon, although unsure of the timeline. https://briarproject.org

    The pros are that there’s zero setup or “self-hosting” required. Just install the app and it works. From their site:

    • Peer-to-peer encrypted messaging and forums
    • Messages are stored securely on your device, not in the cloud
    • Connect directly with nearby contacts - no Internet access required
    • Free and open source software

      Sadly I need an ios app, as well as android. Someone else mentioned Berty which seems to be similar but with android and ios apps.

      Plus briar will work with no internet, and just mesh Bluetooth for message passing instead.

    Berty is an open source messenger app that works with or without an internet connection, and has Android and iOS apps. As it’s peer-to-peer there’s no server component.

        Not a lot but we have used it. It’s beta quality. You need to be in Bluetooth range if there’s no internet - and it works. Good for tent-to-tent texting.

    I have read a bit about the Matrix protocol and once tried running the Synapse home server and Element front end which is also available as Android/iOS apps.

    Matrix is a federated chat protocol in the same way that ActivityPub is a federated social networking protocol. You can host your own Matrix compatible server and chat with people on other servers.

    Recently I watched a video about their recent progress in which they showed a chat working peer to peer over bluetooth low energy when devices did not have access to the internet. Writing this, I just watched another P2P demo video where they show off this functionality once again.

    This means you can use your own chat server as usual when

    • You have an internet connection on your device
    • Your device is on the same network as your server
    • Your device can find a P2P route to the other users through nearby bluetooth devices running this software allowing your device to route through other devices network and bluetooth connections

    Take all of this with a grain of salt as I am not completely sure I understand how the Matrix services work. I hope this helps.

      I did some looking into matrix but couldn’t find if it would still work when the internet is out.

        Not really. You need to use a domain (correct me, if I’m wrong, but I think IP adresses don’t work) to connect to the homeserver.

        In theory you could setup a DNS server in your nezwork, which resolves this domain with the local adress and then it might work, but I’m not sure if the homeserver would like that.

        Also I want to add, that I use TeamSpeak, which works perfectly globally and locally, but it’s for voice chat.

          Aah, yes. You’re right there. You will require a domain for it to work. Although, you could still have it work with a local DNS server for internet outages. You would still be able to chat locally in that case. But yeah, this does not seem like what OP is looking for.

    I have used Rocket.Chat before, their free version supports most of the features they have, and the web client is good. You can setup webhooks in and out for different automations you may want.
