Tasmota with OpenHab or similar - eviltoast

Greetings, internet strangers. I just got a Martin Jerry Tasmota smart switch and would like to connect it to OpenHab or something similar. I have ruled out HomeAssistant because their docker image doesn’t have plugin support and I need to run it on an existing Debian 12 server. I know a little bit about mqtt but not much. If anyone could tell me how or recommend a guide to configuring a Tasmota switch with OpenHab or similar with a mqtt broker that would be great. Thanks.
