How to load bespoke firmware into a plug ?

Hi,

I'd like to flash some bespoke software onto an ESP32-C3 Athom plug I currently have both ESPHome and Tasmota sample plugs so I can pick either for this question.

I've built my bespoke App on the 2.3.2 Arduino IDE and it runs perfectly on a number of ESP32-C3 dev boards (e.g. Seeed Studio & ESP32-C3-DevKitM1-1)

Question: If I use the IDE's 'Export Compiled Binary' option to make a .bin file, can I expect the Tasmota 'Load from File' option to work so that the plug will then run my bespoke firmware after a restart ?

Background:

To avoid bricking my Tasmota plug, I tried to load and run the Tasmota FW on a Dev Board (this worked ok) but when I then tried to 'replace' Tasmota with my code using Tasmota's 'Load from File' option, it failed.

All suggestions welcome 🙂

Thanks.
