Slim Irrigatiesysteem
🌱 Slim Irrigatiesysteem met ESPHome, KC868‑A6 en Dynamische Energieprijzen
Water geven is niet moeilijk — maar het efficiënt, energiezuinig en volledig geautomatiseerd doen, dat is een ander verhaal. In dit project bouwde ik een compleet irrigatiesysteem op basis van:
- ESPHome
- Kincony KC868‑A6
- Home Assistant
- Dynamische energieprijzen via cheapest_energy_hours.jinja (TheFes)
Het resultaat is een systeem dat:
- vijf irrigatiezones aanstuurt
- een pomp schakelt
- lokaal bedienbaar is via hardware‑knoppen
- volledig integreert met Home Assistant
- automatisch draait op de goedkoopste uren van de dag
- en zelfs na een reboot weet wanneer elke zone voor het laatst actief was
- irrigatie duur wordt in de ESP geregeld, zodat een zone niet per ongeluk aan blijft als Home Assistant in de tussentijd herstart
🔧 Hardware: Kincony KC868‑A6
De KC868‑A6 is een veelzijdige controller die ideaal is voor irrigatieprojecten.
| Eigenschap | Beschrijving |
|---|---|
| MCU | ESP32 (WiFi + Bluetooth) |
| Relais | 6 kanalen, 10A, optisch geïsoleerd |
| Ingangen | 6 digitale ingangen (PCF8574) |
| Uitgangen | 8 digitale uitgangen (PCF8574) |
| I²C‑bus | Voor displays, sensoren, uitbreidingen |
| Voeding | 12V input, interne 5V/3.3V conversie |
| Extra’s | RS485, IR, RF, uitbreidingsheaders |

💧 Irrigatiecontroller met ESPHome
De configuratie bevat:
- 5 irrigatiezones
- pompbeveiliging
- OLED‑display
- lokale bediening via knoppen
- persistent “last run” geheugen
- Home Assistant integratie
⚡ Slimme automatisering: irrigeren op de goedkoopste uren
Met dynamische energieprijzen is het zonde om de pomp te laten draaien op dure uren. Daarom gebruik ik de cheapest_energy_hours.jinja template van TheFes.

# https://www.kincony.com/kc868-a6-hardware-design-details.html
# https://www.kincony.com/forum/showthread.php?tid=1963
# Based on ESPHome Sprinkler Controller - https://esphome.io/components/sprinkler.html
# https://community.home-assistant.io/t/sprinkler-automation-with-esphome-a-complete-project/565077
# Change Log
# 2023 01 XX
# Initial version
# 2023 04 09 V03
# fix run duration to seconds
# 2023 04 22 V04
# fix GPIO order to match relay 1- 4
# added % at the lambda return for progress sensor return value
# 2023 04 25 V05
# added nodemcu as sensor to display in HA ui
# added includes for api key en ota password
# 2023 05 07 V06
# added a NTC temp sensor to watch the enclosure temperature
# 2023 05 10 V07
# addjusted settings reference voltage to adjust to actual temp (default 3.3)
# 2023 06 06 V08
# adjusted settings for valves corresponding to switches
# added repeat function
# 2024 04 04 V09
# Corrected the value of KEY ESPHOME_PROJECT_VERSION due to compiling error esphome v2024.3.1
# initializer-string for 'char [30]' is too long
# changed 2023 06 06 V08 to 20240404_V09
# removed the text "Irrigation Controller.,"
# 20260312_V01Peterpc
# Wanneer laatst actief toegevoegd.
# 20260314_V01Peterpc
# Bij reboot laatst actief weer naar HA sturen.
# 20260331_V06Peterpc
# sprinkler tijden bij reboot terug zetten naar bewaarde waarden in flash.
# laatst gestart waarde bij install op huidige tijd zetten in plaats van unknown
# 20260401_V01Peterpc
# de switch in HA gaat bij inschakelen via HA aan, even uit en weer aan, omdat het de status van de valve switch in de esp bij houdt.
# dat is niet handig als je die in een automation als trigger wil gebruiken.
# daarom is er een HA switch toegevoegd, die aan blijft en een status sensor voor de zone.
# de valve switch is ook nog zichtbaar met zijn aan, uit, aan eigenschap, omdat je die niet op internal kan zetten in ESPHome.

📄 automation:alle 5 zones automatisch UIT
Hij werkt op basis van:
sensor.irrigation_controller_time_remaining
zodra die 0 seconden bereikt
zet hij alle stateless zone‑switches uit
