Woop! I survived the shitshow that was 2020. Now, what to do?
I know, I’ll extend my home IoT network, add more sensors, relays, LEDs, some well-being monitoring schtuff. Planning to control/monitor with HomeAssistant running on an RPi 4 (MQTT server, and ESPHome server).
For the rest of January I’ll be adding an ESP a day!

First, a simple 12V relay, powered by this cute lil ESP-01s. Relay will power 2 computer case fans, 1 which will pull air through a carbon filter; 1 will cool an RPi cluster.
