ESP8622 z wyświetlaczem SSD1306 (OLED) DHT22, BH1750 pod ESPEasy

Domoticz part 3.1: ESP Easy on ESP8266 – remote and local OLED display with temperature, humidity, light – weather station

Previously we played around the SSD1306 OLED display as side display for Raspberry Pi. The author of ESP Easy – Richard ten Klooster (https://github.com/ESP8266nu/ESPEasy) – recently updated his project to include new sensors, so today we will update our DHT22 enabled remote sensor for Domoticz with display and light metering. Our weather station will get a remote display. I’ve created such bundle of sensors to allow both temperature and humidity measurement small shack for chopped wood but also to light the way to it after…

Raspberry PI + BME280

BME280 in Domoticz – updating the sensor data via Python

[Update: 30.07.2017 – as of now – latest stable domoticz version supports BME280, so this is now obsolete! The Hardware menu has now I2C Sensors and BME280 is present in submenu] This is a modification of: https://bitbucket.org/MattHawkinsUK/rpispy-misc/raw/master/python/bme280.py, which after you change the IP address and port of Domoticz in ip_domoticz, and creating dummy sensor in Domoticz – “Temp+Humi+Baro” – and then changing the IDX to it’s value in: idx_dummy_bme280 – will update the sensor with the same data as you can see while running the program. This…

DS18b20 with RPi - connections

Domoticz part 4: connecting the DS18b20 thermometer

Temperature readout is one of the first sensor we add to domoticz. It’s a very simple task and allows to connect multiple thermometers via the 1-wire bus. 1-wire means that thermometer has a single data wire, on top of VCC and GND. This wire is used to send back data to 1-wire controller and then it gets verified. What will you need? Hardware: thermometer DS18B20 (Dallas) – comes in variety of housings – usually it’s a chip with 3 pins. It’s good to measure from…

ESP8266 on NodeMCU Amica Board with DHT22 sensor and battery power

Domoticz part 3: ESP Easy – quick and easy sensor for weather station using ESP8266

ESP8266 has become so popular that a beginner can choose from multitude of projects/firmwares and then – just start using them. Advanced IoT adopters will praise it’s quick implementation and stability. Today we will check out the Richard Ten Klooster’s project ESPEasy – https://github.com/ESP8266nu/ESPEasy. Basically ESPEasy is a firmware that can be flashed onto ESP8266 – preferably ESP-12E or ESP-12F and right after boot – we can join it’s WiFi access point (AP) to configure it via web interface. No console needed. Then, it is…
