How to access remotely a Tasmota device, bypassing HA?

Hello, so, my Home Assistant configuration is connected to an unstable WiFi Extender, which needs to reboot, from time to time, since I loose access to my HA.
I now have a Tasmota Smart Plug (Athom) controlling my WiFi extender, but of course I can’t control it if I loose access to HA, and I’m not at the home network. So, basically, I need to access remotely my Tasmota plug, specially in the eventualities that I don’t have access to my HA.
I also don’t want to play around with opening ports on my router and so on.
I heard that a Telegram Bot might be a way to go. Any thoughts? Thanks.
