Pricer Integration
Pricer is a Swedish manufacturer for electronic shelf labels, so called ESL:s. They develop hardware in different formats as well as software for managing signs and price updates.
The integration with Pricer allows for updating signs with live values from IoT sensors as well as displaying text. It is also possible to control the built-in LED.
Configuration
To correctly map displays to the corresponding devices and functions in Lynx, specific metadata keys are required. These keys are outlined in the table below:
| Object | Key | Type | Description |
|---|---|---|---|
| Installation | pricer.exported | Boolean | Indicates if the installation should be exported to Pricer |
| Installation | pricer.store_id | String (UUID) | The store ID in Pricer:s system that this installation represents |
| Device | pricer.esl_code | String | The serial number of the display |
The Pricer integration can utilize the Lynx support for loose connection between Functions (Products in Pricer) and Devices (ESL:s in Pricer) to connect these together. One function can be used with several devices by utilizing the meta-key device_ids.
A Pricer function utilizes two distinct topics for communication:
topic_write: Displays data on the sign.topic_write_flash: Controls the LED on the display.
