Sonoff, MQTT, tasmota device name config - how set

Hi;

In HA overview, my tasmota sonoff basics show up as switches which is OK. Issue is how they are named.

Is it possible to tasmota config device names so they will show up “as configured” in HA overview?
If so, which tasmota settings?

A blurb or link to tasmota config explaining this will assist.

Thanks;
Bill

Here you configure the name. This is how they will show in HA

Thanks @francisp;

Tried that. No effect, even after device reset. Do I have to do a purge of previous entries? How?

That name will show up in HA overview?

Did you use setoption19 1 ? Needs to be done after each change.

Yes; does it persist (need to save)? Or; just a a one shot? (setting it sends whatever HA needs for discovery once)?

Do I have to clear out old names? Restart HA?

SetOption19 1 five minutes ago. No change.

Had to set: both Topic and FriendlyName to desired name, then SetOption19 1.
After that, assigned names appeared in HA overview
Safe to say any tasmota config change requires SetOption19 1 after?
