TPH Sensor Setup Guide - Flux Open Home

1

Position Your Sensor

Place the TPH sensor in your greenhouse, grow room, or target monitoring area. The BME280 sensor measures ambient temperature, humidity, and barometric pressure. Keep away from direct sunlight or heat sources for accurate readings.

2

Power On & Connect to WiFi

Power the sensor via USB. On first boot, it creates a WiFi hotspot. Connect and enter your WiFi credentials through the captive portal.

Bluetooth provisioning is also available from the ESPHome dashboard.

3

Add to Home Assistant

Home Assistant auto-discovers the sensor. Go to Settings → Devices & Services and configure. You'll see three sensor entities: Temperature, Humidity, and Pressure.

4

View Your Readings

Add the sensor cards to your Home Assistant dashboard. Temperature displays in °F or °C, humidity as relative %, and pressure in hPa. Historical data is stored automatically.

5

Set Up Automations

Create automations based on sensor readings. Examples: alert when greenhouse temperature exceeds 95°F, turn on ventilation when humidity passes 80%, notify when pressure drops indicate incoming weather changes.

Keep It Updated

OTA firmware updates appear in Home Assistant. Click Install when available.
