Hi All,
I’m planning to mod a hamilton beach 41036 kettle to be locally controlled by HA. As purchased it uses an ESP32-pico-v3-zero for communication to Alexa.
I hope to reprogram the ESP32 to get rid of the Alexa functions, and use mqtt to control it. The goal is local voice control of the unit without any cloud usage.
I’m going to connect to the esp32 to get logs first, to see what I can learn.
After that I’ll sniff the tx and rx between the ESP32 and the main MCU, to see what signals go back and forth when Alexa is used to control the kettle.
The current problem I am having is finding the GPIO 0 to pull low at reset to enter boot loader mode. Does anyone have any idea if there is a place I can access this contact?
I understand I may not be able to reprogram the existing esp32 module. If I cannot, I would like to find a replacement that I can swap directly with the old one, with the same pinout - this will require a reflow type of substitution.
Failing that I’ll replace the old one with an esp32 that I connect with jumper wires.
Does anyone have any ideas that might help, or could refer me to another resource that might have info on this type of hack/mod? Thx!
