Markus LindenbergMy little magnetic kitchen indoor/outdoor thermometer. Made this from two unused tm1637 modules and a esp32-h2.
I don't like home automation dashboards in the living space so just putting a tablet on the wall was not an option 🤓
I could have made a nice front cover for the PCBs but I wanted it to look technical and unfinished.
The previous version had a pico-w instead of esp32-h2 and a much uglier flat "case" which didn't look as nice as I imagined on the side of my fridge.
Maybe the next iteration will be with e-ink display and battery powered, which is a whole different challenge to make the battery last months.
Algaeman@moreentropy Lighted displays are much easier to read than e-ink. I'd guess most of your power is going to be spent on WiFi, so there may not be as much of a difference on the display power as you think.
@algaeman This is a low power esp32-h2 that can't do wifi, only thread for wireless. So I'm hoping it can be more power efficient compared to a esp32 with wifi.
But yeah, I'm already running the digits at almost minimal brighness for indoor use, I should check how long they last on battery 👍
