 As a first step into smart home automation, I wanted to place temperature and humidity sensors in most rooms of my flat.
 To achieve this, I made some simple ESP8266 boards with an I2C sensor, either SHT21 or BME280, as well as a small 3.3V regulator and a USB connector.
 The data is written into an InfluxDB instance on my NAS.

+    [ "img/esp_env_relais_2.jpg", "Bathroom Relais insides" ],
 ])
