New to home assistant - adding first sensor (shelly 2.5)

Hi,
I’m newbie to all of this so please forgive me if what I’m asking is very basic.
I installed home assistant and mosquitto. I have 2 shelly 2.5, one is flashed with latest version of tasmota as a test.
I followed the instruction from this manual and it seems like it is working - I’m able to connect to tasmota UI and configure everything as mentioned in that manual. It will be used as roller shutter.

The thing that I’m missing is - how do I add it now to Home Assistant? I guess I should add it to the configuration.yaml? If so - I would very appreciate it if someone who is using it as well can share the relevant part in the yaml configuration…

Am I missing more steps?
Your help is much appreciated!

Tnx,
Zohar

Why flash it with Tasmota and use MQTT ??
I have 6 shelly devices all working with HA and Shelly Cloud using the below and they great and respond very quickly

Easy to setup and install, auto finds shelly devices etc

Thank you for your reply. I prefer local solution that is not relaying on cloud…

HI it does not need the cloud it works locally but up to you

in tasmota use

setoption 19 1

That should turn on discovery mode, and home assistant should discover it.
