Over the Air firmware update

I am developing an IoT solution where I deploy remotely operated relays (ESP32 based) at my customers' sites, that are controlled from a central server. The hardware and firmware are already developed.

My issue is that because this solution is still in its early stages, I am finding myself needing to make frequent firmware updates. This implies having to drive to all my customer sites and make the updates locally.

I am looking to wrap my firmware in an Over the Air architecture to allow me to push updates over the Internet from my central server.

Key Words: ESP32. VSCode. PlatformIO. Over the Air. OTA. IoT. Remote Relay.

Skills: Arduino, Internet of Things (IoT)
