I have integrated a esp8266 with Esphome with name mystudy.
I have connected a NTC thermistor that is about 8.9K @ 30Deg C. So I assume it is a 10 K thermistor @ 25 Deg C. The thermistor is added in series with a 10 K resistor, with thermistor downstream of the resistor. The Junction of the combine is connected to A0. The top pf resistor is connected to 3.3 V.
The mystudy.yaml file is as below
esphome: name: mystudy platform: ESP8266 board: d1 wifi: ssid: "SSID1-2.4G" password: "[email protected]" ap: ssid: "Mystudy Fallback Hotspot" password: "8csfgeTMT3UB" captive_portal: logger: api: ota: ### switch: - platform: gpio id: kitchen_pump name: "led" pin: number: D9 inverted: True - platform: gpio id: ntc_vcc name: "ntc_vcc" pin: number: D0 inverted: False sensor: - platform: ntc sensor: resistance_sensor calibration: b_constant: 3950 reference_temperature: 25°C reference_resistance: 10kOhm name: NTC Temperature - platform: resistance id: resistance_sensor sensor: source_sensor configuration: DOWNSTREAM resistor: 10kOhm name: Resistance Sensor - platform: adc id: source_sensor pin: A0
The temperaure shown in my dashboard is 70 Deg C where as it should be 29.8 Deg C.
What have I missed.
