Dear Mastodonians! I have the problem that I have been recently forced to use Whatsapp. I bought a burner phone and got a prepaid SIM for it. This is a crappy solution and I am looking for an alternative. Something that forwards ingoing Whatsapp messages to Threema/Signal/etc. Maybe even to two different phones (wife's and mine). I don't need to be able to answer/send messages, only need to read them. And no, it is not possible to convince others not to use Whatsapp and yes, I need the messages.
I think I have found a solution: A matrix server is now running on a dedicated VPS with several bridges: IRC, Signal, Telegram and WhatsApp. Looks very promising!
@DL6MHC A bit of guessing here. Can Matterbridge and Mattermost work?
I'm not completely up to speed on which protocols Matterbridge support, maybe it supports Whatsapp?
