My MQTT sensors

Hass-MQTT-sensors

Home Assistant - MQTT sensors (ESP8266).

List of MQTT nodes:

Surround receiver sensor

My receiver is placed inside my tv bench with a closed door. I had a temperature sensor placed above the receiver for a couple of weeks, and the highest temperature I measured was 38 degrees celsius. There was a couple of holes in the back, but not big enough to replace the air. What I did was to create a new hole in the back, big enough to mount a 120mm x 120mm fan. This fan moves new air into the tv bench (positive vs negative pressure).

Hardware:

• NodeMCU v2
• 12v power supply
• DS18B20 temperature sensor
• TIP120 transistor

Code (Arduino)

Temperature + Humidity (bedroom)

Just a simple temperature / humidity sensor, placed in my bedroom.

Hardware:

• ESP8266 WeMos D1
• DHT22 (better resolution than DHT11)

Code (Arduino)

Camera control (relay)

I wanted my network camera to be turned off when I'm home, and on when I'm leaving. This is just a simple MQTT relay.

Hardware:

• NodeMCU v2
• Relay

Code (Arduino)

Kegerator

I have a kegerator in the guest room. What I needed was a couple of sensors to monitor temperature and if the door was closed.

Hardware:

• NodeMCU v2
• DS18B20 temperature sensor
• Door sensor

Door bell

I want to get a notification if somebody rings my doorbell. I'm not able to hear the doorbell now if any doors to the entrance is closed and/or if we are listing to music or the TV is on.

Hardware:

• ESP8266 WeMos D1
