What is this repository for?

Running Tessel2 + relay module as a KNX actuator.

• Exposes a simple REST api (via restify) that you can use to configure group addresses
• Persists configuration to /app/storage so that you don't need to reconfigure after say a power outage.

How do I get set up?

• Summary of set up

$ t2 root
$ t2 push index.js

REST assured: configuring your KNX actuator doesn't require ETS anymore :)

JUC: Just Use Curl to configure the actuator

# get current configuration 
$ curl -s  http://TesselKNX.local:8080/relays
{"1":{"state":false,"groupAddrs":{"control":[],"status":[]}},"2":{"state":false,"groupAddrs":{"control":[],"status":[]}}}
 
# bind control group address 5/0/8 to relay 1 
$ curl -s -X PUT http://TesselKNX.local:8080/relay/1/control/5/0/8
{"result":"OK","relays":{"1":{"state":false,"groupAddrs":{"control":["5/0/8"],"status":[]}},"2":{"state":false,"groupAddrs":{"control":[],"status":[]}}}}
 
# bind a 2nd control group address to relay 1 
$ curl -s -X PUT http://TesselKNX.local:8080/relay/1/control/5/0/80
{"result":"OK","relays":{"1":{"state":false,"groupAddrs":{"control":["5/0/8","5/0/80"],"status":[]}},"2":{"state":false,"groupAddrs":{"control":[],"status":[]}}}}
 
# bind status group address 2/3/4 to relay 1 
$ curl -s -X PUT http://TesselKNX.local:8080/relay/1/status/2/3/4
{"result":"OK","relays":{"1":{"state":false,"groupAddrs":{"control":["5/0/8","5/0/80"],"status":["2/3/4"]}},"2":{"state":false,"groupAddrs":{"control":[],"status":[]}}}}
 
# delete all control group addresses for relay 1 
$ curl -s -X DELETE http://TesselKNX.local:8080/relay/1/control
{"result":"OK","relays":{"1":{"state":false,"groupAddrs":{"control":[],"status":["2/3/4"]}},"2":{"state":false,"groupAddrs":{"control":[],"status":[]}}}}

That's all there is to it !
