The evolution of plugins
From an extra field for a barely used stream to a powerful asynchronous mechanism to modify device messages using third-party data.
Plugins are the key instance in flespi responsible for the transformation of the received message before it departs to the destination.
Plugins apply to device messages.
You can apply multiple plugins to a message in the specified order.
Plugins can inject values obtained from third-party services, e.g. geocoding or LBS data.
You can request the development of a custom plugin to meet your specific business needs.
Plugin types
| Plugin type | Description | Type |
|---|---|---|
| item-fields | add static fields to the designated item, some of the fields can be stored as message parameters | Add params |
| item-telemetry | add cached telemetry values in place of missing device message parameters | Add params |
| msg-expression | add new message parameters as a result of evaluating expressions | Add params |
| msg-geofence | detect if the position from a given device message is inside a specified list of geofences; add parameters with the status (in/out) and geofence name to the device message | Add params |
| msg-erase | remove the listed parameters from the message | Delete params |
| msg-pvm-code | execute PVM code to process the message | Custom parsing |
| google-reverse-geocoding | resolve the position address using Google reverse geocoding and add it to the message | Geocoding |
| nominatim-reverse-geocoding | resolve the position address using Nominatim reverse geocoding (OSM) and add it to the message. Public and private servers supported. | Geocoding |
| here-reverse-geocoding | resolve the position address using Here reverse geocoding and add it to the message | Geocoding |
| wialon-reverse-geocoding | resolve position address using reverse Gurtam Wialon geocoding and add it to the message | Geocoding |
| google-wifi-geolocation | resolve Wi-Fi router MAC address information into location data using Google Wi-Fi Geolocation API and add them to the message | Geocoding |
| wialon-lbs-geocoding | resolve position coordinates using LBS Wialon geocoding and add them to the message | LBS |
We regularly add new plugins to the list. Follow the “plugins” tag on our forum to keep updated about all plugin-related news
Possible scenarios
Add, remove, or replace message parameters
Add reverse geocoding data into messages
Configure custom parsing logic for message payload
Add geofence status into messages
Add LBS data into messages
