Side by side, from the sources
Asmoday vs Aeshma
One of these is descended from the other: the later figure inherits the earlier one's name, and usually very little else. Aeshma-daeva to Ashmedai to Asmodeus — the strongest name-level link between the two traditions.
Demonic · Goetic Spirit · c. 700 BCE
Asmoday
also called Asmodeus, Asmodai, Sydonay, Ἀσμοδαῖος, אשמדאי
Commands seventy-two legions, one for every spirit in the book. He is the Asmodeus of Tobit, who killed Sarah's seven husbands and was driven into Upper Egypt by Raphael, and behind that the Avestan Aeshma-daeva, the demon of wrath — one of very few Goetic spirits with an ancestry that can be traced.

Deity · Persian · c. 1000 BCE
Aeshma
also called Aeshma Daeva, Eshm, Khashm, Aēšma
The demon of wrath and of the bloody club. He also supplies the most defensible etymology for Asmodeus: *Aeshma-daeva* to *Ashmedai* to *Asmodeus*.

No shared office is recorded. Where two figures are said to be the same and share no job description at all, the identification is usually doing polemical work rather than descriptive work.
