A network in Janitoo is holded by Mosquitto. It use the Dynamic Home Configuration Protocol to allow nodes to communicate each other.

Each node on a network has its own HADD : xxxx/yyyy where 0 <= x,y <=9.

Nodes with an HADD ending in 0000 (ie 1234/0000) are called controllers. They are responsible of the nodes in their subnetwork (ie 1234/0001).

Supervisors maintains a "map" of the network. There are of 2 types : primaries and secondaries.

The primary will serve configuration parameters for the nodes.

The network is managed by a finish state machine. Only the fail mode can be considered as usuable.

A node holds values.

There is many genres of values :

• system : needed by the protocol itself.
• config : used to configure nodes and values
• basic : base values. Used by nodes themselves and andvanced users.
• user : for common users
• command : to launch advanced commands ie pairing

Examples of nodes/values

• an ups is a node (janitoo_nut). battery_level, upsstate, ... are values
• a vacuum is a node (janitoo_roomba). baterry_level, dock state but also clean, dock commands are values
• an rrd source is a node
• an arduino is a node

...

If your familiar with openzwave and the zwave protocol, janitoo is a kind of zwave over mqtt.

Ths bus and components are the developpers API of the nodes in Janitoo.

A bus can hold components and is associated to a controller A component is mapped to a node. The map is done using a configuration file

Due to its low memory footprint, janitoo can be used on many hardwares :

• Arduino mega. Actually, it's impossible to install it on an Uno.
• Raspberry : the 0 will be supported (python). The janitoo_hostsensor with 7 nodes and about 100 values only takes 3% of memory and 7% of cpu on a Raspberry B.
