The suggestion of using an external clock module is so obvious, I don’t know how I didn’t come up with it myself. Thank you for that!

Thank you for the advice, but it’s not really what I’m looking for. I am looking for something really lightweight for now, and the ESP32 is a bit overkill. And codeless deployment sounds horrible, I want to actually write the ode myself, I should have mentioned that!

Yeah, I think I’m gonna ignore networking for now. I’ll have a look at your recommendation, thank you!
