Supported Hardware

Tested with:

SMA SunnyBoy 5000TL-21
SMA Sunny Tripower 8000TL-10
SMA Sunny Tripower 12000TL-10

Should work with other SMA inverters as well - please let me know!

Configuration

plugin.yaml

sma:
    class_name: SMA
    class_path: plugins.sma
    bt_addr: 00:80:25:21:7F:58
    # password = 0000
    # update_cycle = 60
    # allowed_timedelta = 10

Description of the attributes:

bt_addr: MAC-address of the inverter (find out with ‚hcitool scan‘)
password: password for accessing the inverter in user-mode (default 0000)
update_cycle: interval in seconds how often the data is read from the inverter (default 60)
allowed_timedelta: allowed difference of inverter to system time - if above, inverter is set to system time - set to -1 to disable (default 60)

items.yaml

The item having sma = PLUGIN_ACTIVE can be set to True/False in order to connect/disconnect to the inverter during night.
