b-parasite-esp32/bridge

What's a Bridge (or a Hub)?

b-parasite periodically broadcasts its sensors readings via bluetooth low energy (BLE). Usually, a bridge (a separate device) is used for capturing those broadcasts, decoding them, and forwarding them somewhere else (like MQTT or directly to a database).

An ESPHome-based Example Bridge

This directory contains a hub implementation based on the ESPHome project, which runs on the popular ESP32 microcontrollers.

The parahub.yaml file defines an ESPHome project using the b_parasite platform. This platform has not yet been merged in the official ESPHome repository, so if you want to use this example bridge, you'll need to use the rbaron/esphome fork.

Secrets

parahub.yaml contains some directives such as !secret mqtt_password, which instructs it to read secrets from a secrets.yaml file.

This file is usually not commited to version control, so you'll need to populate your own. Here's an example:

# Example secrets.yaml
wifi_ssid: WIFI_NETWORK_NAME
wifi_password: WIFI_PASSWORD
mqtt_broker: MQTT_BROKER
mqtt_password: MQTT_PASSWORD
ota_password: OTA_PASSWORD

Alternative

parasite-scanner is a purpose-built BLE-MQTT bridge for b-parasites, and runs on Linux and macOS.
