Install Tasmota on ESP-01

I would like to install Tasmota on ESP-01 is this possible?
I have Tasmota working on NODE MCU and works like a charm with HA.

the reason is when I flash my ESP-01 with Arduino I can’t connect to MQTT on HA. but Sonoff can

Not knowing which version of the ESP-01 you have it’s hard to say, but my is guess is that it is likely not going to work due to the storage limitations. You’d be better off going with another Sonoff or a Wemos/NodeMCU type board.

This is not the tasmota support forum, but I suggest you simply read the tasmota docs here:

Thanks. I know but thought it’s still HA related issue I guessed.
