Tazmoda 13.1.0 on Sonoff Basic - Switch not recognized by Home Assistant?

Has anyone experienced this issue? I can browse the SonoffR2 Basic by its IP address. It appears comparable to a dozen other switches but Home Assistant doesn’t recognize it. I have verified MQTT sees the transactions.

Tasmota integration or MQTT integration ? SetOption19 0 or 1 ?

SetOption19 Set to 1

Try Setoption19 0, and install the Tasmota integration

Who knew after Tasmoda V10 the Tasmoda integration is required and setting setoption10 to 1 is not.
Thank you for your assistance!!

Do you have any insight where I could learn more about entity naming? Is it possible/advisable to remove old unused entitles to avoid duplication issues in the future?
