Installation

Install on Raspberry PI image (low write) emonCMS from https://github.com/emoncms/emoncms/blob/master/readme.md

Fire up a command prompt and install the bluetooth stack

sudo aptitude install bluez python-bluetooth

Plug in a CLASS 1 BLUETOOTH USB adapter to the PI.

Run command

lsusb

should be shown similar to this...

Bus 001 Device 004: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Start the bluetooth service

sudo service bluetooth start
sudo service bluetooth status

Run command hcitool scan

Should find your SMA inverter...

Configuring emonCMS to detect nodes

emonCMS should automatically detect and show the solar values inside the "Nodes" page, however they will be missing descriptions.

Click on EmonHub and cut and paste the below into the configuration editor, then click SAVE.
