Home Assistant : Running on Raspberry Pi 3 Wemos D1 mini(ESP8266) : Programmable WiFi controller (collects data or control switch/relay) ESPHome : Deployable firmware with YAML configuraion DHT11 : Temperature humidity sensor DS18B20 : Temperature sensor Relay : Toggle switch BMP180 : Air pressure sensor HC-SR501 : Passive Infrared sensor WS2812 : Addressable LED Analog AC Current Sensor : Failed to deploy (cannot get precise value, don’t know product’s defect or inproper wiring or compatibility issue) tpLink P110 : Smart Plug provides measuring power consumption Wemos D1 R1 : just tested.
Beelink Mini S I wasn’t satisfied by Pico PC so,
I bought another mini PC. the Beelink Mini S
Here are some specs.
CPU : Intel N95 Memory : 8GB SSD : 256GB Display Output : HDMI x 2 USB : USB-A x 4 Ethernet : 1 GbE x 1 Wifi : Wifi 5 Better than Pico PC
Silent : most important Pico PC doesn’t include PWM controlled FAN.
ESP8266 + IR Receiver + IR Transmitter When I was using raspberry pi, I bought a IR transceiver module for Arduino. and used it for several years. IR transceiver
And this year, I am interested in ESP8266, so I bought another IR receiver, IR transmitter.
Installed. Install esp8266 and voltage converter on breadboard.
Install IR receiver and IR transmitter in front of tv
My Raspberry Pi 1 Bought : ₩58,000 2013/04/24
with : PiFace, BOARD, I/O EXPANSION, RASPBERRY-PI (₩48,570) At First : install raspbian. tested relay, and tested led on PiFace
As a IR Remote controller : telegram-bot-try2, 2019 May IoT project
As a Thermal sensor : finally just read DHT11 temperature/humidity and send it to the server.

Story I wanted to implement automatic LED light, when I approach kitchen.
Prepare ESP8266 compatible board. (I use ESP01 board this time) WS2812B LED Strip (5v addressable LED) HC-SR501 PIR Sensor (body detection sensor) Wiring WS2812B
vcc : to USB 5v positive pin gnd : to USB ground pin data : to GPIO1 of ESP01 HC-SR501

Bought Pico PC I bought Pico PC via indiegogo fundraising several months ago.Oct 2022 - Bought Pico PC
Long-waited Pico PC is just arrived today
First impression Booting the box. Next. the boring win10 boot sequence starts.. (before installing ubuntu, let’s see what is win10, what it looks like)
(yeah, it is windows 10. I don’t need windows 10.
