SBFspot, formerly known as SMAspot, is an open source project to get actual and archive data out of an SMA® inverter over Bluetooth or Ethernet (Speedwire®) It works on either Linux (Raspberry Pi) and Windows.

=Installing SBFspot=

There are excellent instructions here: https://github.com/SBFspot/SBFspot/wiki/Installation-Linux-SQLite

If you're planning to run SBFspot on Raspberry Pi, you can skip this installation instruction and just run [https://github.com/SBFspot/sbfspot-config sbfspot-config]

'''It is important that you log in use the following commands with the user that owns domoticz (for example the 'pi' users)'''

Things to remember:

#- Do not use a windows editor, just use 'vi' [ or the simple nano ] to edit the config file
#- Always login with the same user as domoticz (pi user for raspberry pi)
#- Follow the wiki to the letter
#- If you upgrade from an older version, check if you have all parameters from the latest configuration file in your config file, if needed, add the missing parts
#- the wiki is for a unix installation, the output path can not be C:\Temp
#- first test if it works, check if you get have data files (cvs/spot files)
#- if you change something in the configuration file, disable/enable SMASpot in domoticz to read the new configuration file

=Add SBFspot to Domoticz=
In Domoticz hardware section, add "SBFSpot (SMA)",

For Location: enter the SBFspot.cfg path (e.g. '''/usr/local/bin/sbfspot.3/SBFspot.cfg''')

Note that since the 19th November 2015 build it is possible to use SBFSpot files that record logs for multiple inverters by suffixing the configuration line with a colon, followed by the inverter serial number. For example:

'''/home/pi/SBFspot/SBFspot/bin/Release_SQLite/SBFspot.cfg:1234567890'''

=Data retrieval method=
Internally, domoticz relies on SBFspot to generate logfiles in the spot format. It is therefore important that SBFspot is kept running in the background (e.g. as cronjob). See [https://github.com/domoticz/domoticz/blob/development/hardware/SBFSpot.cpp SBFspot.cpp] for details.

#Search for 'OutputPath', 'Plantname', 'DateFormat', and 'TimeFormat' in the config file
#Build output path filename from given config strings (<code>sprintf(szLogFile, "%s%s-Spot-%s.csv", strftime_t(m_SBFDataPath.c_str(), atime), m_SBFPlantName.c_str(), szDateStr);</code>)
#Read the output file SMA_POLL_INTERVAL per minute (default once per minute), but only if the seconds in current time are >20 (probably to give SBFspot time to query)
#Check if the last line is newer than the one we have, if so, store and update power data
