This ESP32 board will be controlling the low-voltage blinds in the apartment. Happy that the normal AC switches work as contacts. (Not sure why I doubted they would).

Discovered [nushell](https://www.nushell.sh) this weekend. Looks pretty cool. Tried it, but there are two things that prevent me from making it my new default shell:
1. pyenv: pyenv init does not work with nushell
2. ESP-IDF: ESP IDF's export scripts do not work with nushell

I just finished work on this cute little #wifi scanner. Build on #esp32 also designed and #3dprinted little case for it. RGB led indicator is showing what intensity of signal wifi has and boot button on a back can select only specific ssid to track its strength. This all was done for #noApparentReason

I just wrote a blogpost about the system that I've designed to optimise our power consumption so that we can do everything with a 25 A main fuse.
There are an increasing number of networked devices switching things on and off at the best time to consume the cheapest and most abundant electricity.

Here is a dumb question. I have this ESP32 module: https://www.amazon.co.uk/dp/B07VJ34N2Q?ref_=ppx_hzsearch_conn_dt_b_fed_asin_title_2

Which board would I select in the Arduino app for this?
