Thanks to some makers on here, I got an #ESP32 with a max6675 K-type thermocouple temperature sensor running #ESPHome

This stuff is getting entirely too easy.

I will say, though, I bought these ESP32s that were labeled ESP32 -32 Development Board TYPE-C CH340C and they seem like a pain. I couldn't get them to flash using USB-C to the USB-C port. I ended up pulling out a CP2102 USB UART Bridge to use with it. That seemed to make it work.

It just popped up in #HomeAssistant. I was expecting to arm wrestle it, be confused, swear at it a little, but no. Completely disappointed at not needing to yell at clouds.

This is basically the prototype on my desk. Eventually I want to hook it up to my fireplace temperature sensor.

@paco A lot (most) esp32 usb-c devices will only charge/flash over a usb-a to usb-c cable. USB-C ports need to be pulled down with a resistor (typically 5.1 kΩ). Some dev boards are missing these resistors, which causes them to not work with USB-C to USB-C cables. Using a USB-A to USB-C cable will likely work for you.

Strange, I have a few ESPs, different models and I flash them all on my MacBook USB-C to USB-C. Most difficult part is to be sure to have a data cable at hand and not one of those charging only cables.

@scottymace awesome. I will try that.

I also had to power it on holding the boot button to get into a flashing mode.

I’m going to post my findings on the esphone forums so maybe the next person doesn’t have this issue.
