Hello, i have downloaded your Tasmota Firmeware from 2022 and connected my Board via MQTT to Home Assistant, the communication to Home Assistant has a very long delay. several minutes
Google and Hatgpt both says thats because of the Old Firmeware.
Could you please Update the Tasmota Firmeware.

Thanku so much.
