node-red-contrib-thekey

This package contains nodes to communicate with lockers from the French theKeys' firm through its gateway product (https://store.the-keys.fr/en/accessories/11-gateway.html)

It's compose of :

• 1 configuration node thekeys-gateway that contains properties of the gateway use to pilot locks.
• 1 node thekeys-lock that represent a lock to remotly pilot

requirements

Thispackage depends on crypto-js and requestnodes.

thekeys-gateway

The configuration contains 4 properties :

name : the name you decide to give to the theKeys gateway

host: the gateway IP adress. It can contains an hostname. Default value isthekeys.local

port (optional) : the port used to communicate with the gateway (in case of using NAT rules on router)

checkState : it define if you want the node to avoid posting to gateway an open (or close) command while the state of the desitnation lock is already opened (or closed). When checked (set to true), the node will not send open command to lock considered opened (stored state set to opened). This will avoid unusefull url call to gateway and then will not charge it unusefully. If this property is not checked (se to false), command will be post to gateway unconditionely.
