My own chicken coop automation

Poulailler

My chicken coop automation.

Automatisation de mon poulailler. Ce projet est majoritairement en anglais, non pas pour faire le mec qui s'y croit, mais simplement pour pouvoir partager sur les forums internationaux.

Goals

• Automatic open/close door as per sun light and/or consign
• Autonomous but ...
• ... connected to my home dashboard : wakeup consign, display critical figures on my dashboard and raise alarm in case of trouble.

ESP8266 GPIOs

• ADC : power supply monitoring (internal)
• GPIO0 : enable aux power (low)
• GPIO2 : 1-wire
• GPIO4 : Water warming
• GPIO5 : DHT22
• GPIO15 : Door in stop position (high depend on GPIO12/13)
• GPIO013 : Door up (high)
• GPIO012 : water warming (high)

DS2413 PIOs

• PIO.A : sun light (low)
• PIO.B : water low (low)

Topics

• Poulailler/Perchoir/Temperature : as the name said

• Poulailler/Perchoir/Humidite : as the name said

• Poulailler/Eau/Niveau : Suffisant / Vide

• Poulailler/Luminosite : Jour / Nuit

• Poulailler/Alim : Power supply

• Poulailler/Memoire : available memory

• Poulailler/Reseau : Network we are connected to

• Poulailler/Reseau/Change : when we switch to another network

• Poulailler/Wifi : time to connect to the WiFi network

• Poulailler/MQTT : reconnect duration

• Poulailler/Error : Error messages

• Poulailler/Message : various messages, output, ...

• Poulailler/Command : MQTT commands topic ...

Hardware

• MX1508 H-Bridge
• 3a77553800000091 : DS2413 - Day light probe
• 28ff8fbf711703c3 : DS18B20 - Watter temperature

Test Bat

ADC = 5v * 25.1 / (100 + 25.1) = 1.0032v I = 5 / 125.1K = ~ 40uA

Scenarii

Startup

The goal is the reach a stable and known door position. MQTT data has to be ignored has we don't know if they are valid or outdated.

1. Day or Night ?

   1. Power Aux
   2. Reading Day (publish water as well)

2. Door position ?

   • if Day
     • Door open
   • if Night
     • Door close

Running

WIP : to be ignored.

• Perchoir : every 5 minutes. No action
• Aux : every 15 minutes
  • Water : if too low, error at smart home dashboard level, prevent warming
  • light :
    • If Day -> Night close door after 5'
    • If Night -> Day open the door
