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.

Great guide on loading bespoke firmware into a plug! It's always interesting to learn about customizing hardware with tailored software. For those who might be curious about the broader context of this process, what is bespoke software development? It’s amazing how specialized software solutions can optimize hardware performance.
