Send DMR SMS messages via the SharkRF openSPOT HTTP API

npm install node-red-contrib-openspotsms

A Node-Red module to allow DMR SMS messages to be sent using the SharkRF openSPOT.

This node will take a text string and send an SMS message to the configured DMR radio via the openSPOT HTTP API.

An earlier implementation of this is described in the blog post linked below where it was being used to send SMS messages to the DMR ID on a new DXCC spots.
