It’s a bit sad how deserted this community is, would love to connect more with other makers.

Let’s rattle the cage a bit, who of you is here, and what are you working on?

I’ll start: A wireless cryptographic keystore & signer. Keys are generated with the hardware RNG and stored AES-encrypted with the user’s password, and you can request signatures via BLE.

    Simple (yeah right) temperature control for my wife’s new greenhouse. In other words a thermostat, but also reporting inside and outside temps to a small touch display in the house, where the settings can also be adjusted.

    My goal is for the code to be updatable via OTA so I can seal the esp32 in a waterproof box. Running into problems with OTA but I won’t go into the gory details. But if anybody has solved the problem of controllers with OTA code running on them not showing up as “network ports” in the Arduino IDE so new code can be updated as simply as over usb (which works in multiple how-to videos) please let me know what makes that work.

    Also struggling with communication range of the esp32. The initial app using Node Red couldn’t reach the house wifi router, so I tried peer-to-peer using ESP-Now, with an esp32 halfway as a repeater. This worked but ESP-Now isn’t really a network, so you have to write your own code for things like registering nodes and keeping track of unreceived messages. So I might switch to PainlessMesh, a proper network that does these things. Or just get a wifi extender so Node Red will work - I really Node Red’s whole ecosystem.
