This program is designed for the optimal consumption of solar energy for heating a country house, heating water and watering the garden with optimal battery discharge (no more than 50%) during the day.

The system operates on the basis of the service protocols of the Tuya sensors and the service protocol of the Solarman type recorder (On the example of a hybrid station of the Deye model: SUN-12KSG04LP3-EU)

Integration testing of the code was done on the basis of the following equipment:

• hybrid solar station of the Deye model: SUN-12KSG04LP3-EU with solar panels
• battery: GBL2.45K3(LFP) 4 pcs
• Tuya Smart Life WiFi Thermostat Electric Floor Temperature Controller 5 pcs
• Tuya EU Smart Plug,16A WIFI Smart Socket 4 pcs
• Tuya Wifi Temperature Humidity Sensor 2 pcs
• 1P+N WiFi Smart Circuit Breaker Voltage Energy Power kWh Meter Time Relay Switch 1 pcs

• spring.profiles.active: "${SPRING_PROFILES_ACTIVE:dev}":

-- dev: log info to "CONSOLE"
-- prod: log info to "FILE"

• logging: (log info to "FILE")

-- file: "${LOG_FILE:smart-floor}"
-- folder: "${LOG_PATH:./logs}"
