wireless-sensor-mqtt 🌡

MQTT client reporting measurements of FT017TH wireless thermo/hygrometers

Requirements

• MQTT broker
• FT017TH sensor
• CC1101 transceiver
• Linux machine with CC1101 connected to SPI port & GDO0 connected to some GPIO pin (wiring instructions for raspberry pi)

Setup

$ pip3 install --user --upgrade wireless-sensor-mqtt

Usage

$ wireless-sensor-mqtt \
    --gdo0-gpio-line-name GPIO24 \
    --mqtt-host HOSTNAME_OR_IP_ADDRESS \
    --mqtt-topic-prefix MQTT_TOPIC_PREFIX

Measurements will be published on topics MQTT_TOPIC_PREFIX/temperature-degrees-celsius and MQTT_TOPIC_PREFIX/relative-humidity-percent (e.g., living-room/temperature-degrees-celsius with --mqtt-topic-prefix living-room).

Add --debug to get debug logs.

MQTT via TLS

TLS is enabled by default. Run wireless-sensor-mqtt --mqtt-disable-tls … to disable TLS.

MQTT Authentication

wireless-sensor-mqtt --mqtt-username me --mqtt-password secret …
# or
wireless-sensor-mqtt --mqtt-username me --mqtt-password-file /var/lib/secrets/mqtt/password …

Home Assistant 🏡

Home Assistant will detect two new sensors automatically, if connected to the same MQTT broker and MQTT discovery is enabled (enabled by default since version 0.117.0).

When using a custom discovery_prefix, run wireless-sensor-mqtt --homeassistant-discovery-prefix custom-prefix ….
