Hi,
I think something in the API changed. I had to modify the postData a bit to make it work:

this.postData = {'on': 'control,{controllableNodeId:' + this.switch_id + ',action:"ON"}', 'off': 'control,{controllableNodeId:' + this.switch_id + ',action:"OFF"}'};

Initialization of homebridge shall make a call to /gateway/apipublic/logon with password in payload in order to enable further command

Hi,
thanks for the great plugin. Would it be possible to make it read the current power (Watt) as a sensor? Very useful to trigger a notification if power is going wild.

You can poll the power with this command:
curl --silent -H "Content-Type:application/json" http://[SMAPPEE_IP_ADDRESS]/gateway/apipublic/reportInstantaneousValues | python -c 'import json,sys;obj=json.load(sys.stdin);print obj["report"]' | sed 's/.* activePower=//' | sed 's/..*//'

Thanks in advance.
