77_SMASTP.pm: Support for SMA Sunny Tripower Inverter-> Deprecated. Please use 76_SMAInverter.pm
FHEM-Module for the SMA Energy Meter, a bidirectional energy meter/counter used in photovoltaics.
This module requires:
- Perl Module: IO::Socket::Multicast
On a Debian (based) system, these requirements can be fullfilled by:
- apt-get install libio-socket-multicast-perl
Before you start using 77_SMAEM.pm, you should try the test programm smaem_test.pl. It will read data sent by the SMA-EM over multicast and will print it to the terminal.
Concerning multicast: as long as your FHEM-host is on the same layer2/3 subnet (LAN) as your SMA-EM, multicast will pretty much behave like broadcast and you have nothing to worry about. If the receiving host is behind on or more routers, you have to make sure, that those routers have multicast forwarding enabled and configured.
Beware: some cheap soho-switches in the 50 euro class pretend to work with multicast but inexplicably block random multicast groups. You either have to switch to a better switch or use a super simple one (10 Euro), which doesn't understand multicast at all and will just treat it as broadcast.
Once you get proper readings with smaem_test.pl, you can install 77_SMAEM.pm just by copying it to your FHEM-installation.
Once copied to four FHEM-installation folder ("/FHEM"), load the module with
reload 77_SMAEM
Then you can define your SMA-EM like this:
define <name> SMAEM;
"The attibut interval" defines the update interval. If not set, it defaults to 60s. Since the SMAEM sends updates once a second (firmware 1.02.04.R, March 2016), you can update the readings once a second by lowering the interval to 1, which is not recommended, since it puts FHEM under heavy load.
Example:
define DP11_SMAEM SMAEM
attr DP11_SMAEM alias SMA Energy Meter
attr DP11_SMAEM group Photovoltaik Anlage
attr DP11_SMAEM room Zähler
attr DP11_SMAEM interval 120
attr DP11_SMAEM powerCost 0.28
attr DP11_SMAEM feedinPrice 0.124
attr DP11_SMAEM icon measure_power
attr DP11_SMAEM stateFormat {sprintf("%.1f",ReadingsVal($name,"state",0))." W"}
define DP11_SMAEM_LOG FileLog ./log/DP11_SMAEM_LOG-%Y.log DP11_SMAEM|DP11_SMAEM:.*
77_SMAEM.pm is in principle capable of supporting several SMA-EMs but it has not been tested. In case you have more than one SMA-EM, please contact me. Each reading of each SMA-EM will be uniquely named containg the serial of the SMA-EM it came from, so you can distinguish between different SMA-EM inside FHEM.
FHEM Support for SMA Inverters over "Speedwire" TCP/IP (=Ethernet) network. Tested on Sunny Tripower 6000TL-20, 10000TL-20 and Sunny Island 4.4 with Speedwire/Webconnect Piggyback.
This module requires:
- Perl Module: IO::Socket::INET (apt-get install libio-socket-perl)
- Perl Module: Date::Time (apt-get install libdatetime-perl)
- Perl Module: Time::HiRes (In Debian/Ubuntu/Raspbian part of default per installation)
- FHEM Module: 99_SUNRISE_EL.pm
- FHEM Module: Blocking.pm
define <name> SMAInverter <pin> <hostname/ip>
- pin: User-Password of the SMA Inverter. Default is 0000. Can be changed by "Sunny Explorer" Windows Software
- hostname/ip: Hostname or IP-Adress of the inverter (or it's speedwire piggyback module).
- Port of the inverter is 9522 by default. Firewall has to allow connections on this port!
###Operation method The module sends commands to the inverter and checks if they are supported by the inverter. In case of a positive answer, the data is collected and displayed in the readings according to the detail-level.
If more than one inverter is installed, set attributes "target-susyid" and "target-serial" with an appropriate value.
The normal operation time of the inverter is supposed from sunrise to sunset. In that time period the inverter will be polled. The time of sunrise and sunset will be calculated by functions of FHEM module 99_SUNRISE_EL.pm which is loaded automatically by default. Therefore the global attribute "longitude" and "latitude" should be set to determine the position of the solar system
By the attribute "suppressSleep" the sleep mode between sunset and sunrise can be suppressed. Using attribute "offset" you may prefer the sunrise and defer the sunset virtually. So the working period of the inverter will be extended.
In operating mode "automatic" the inverter will be requested periodically corresponding the preset attribute "interval". The operating mode can be switched to "manual" to realize the retrieval manually (e.g. to synchronize the requst with a SMA energy meter by notify).
During inverter operating time, the average energy production of the last 5, 10 and 15 minutes will be calculated and displayed in the readings
"avg_power_lastminutes_05"
"avg_power_lastminutes_10"
and
``"avg_power_lastminutes_15".```
Note: To permit a precise calculation, you should also set the real request interval into the attribute "interval" although you would use the "manual" operation mode !
The retrieval of the inverter will be executed non-blocking. You can adjust the timeout value for this background process by attribute "timeout".
get <name> data
The request of the inverter will be executed. Those possibility is especifically created for the "manual" operation mode (see attribute "mode").
- interval : Queryintreval in seconds
- detail-level : "0" - Only Power and Energy / "1" - Including Voltage and Current / "2" - All values
- disable : 1 = the module is disabled
- mode : automatic = the inverter will be polled by preset interval, manual = query only by command "get <name> data"
- offset : time in seconds to prefer the sunrise respectively defer the sunset virtualy (0 ... 7200). You will be able to extend the working
period of the module. </li> - SBFSpotComp : 1 = the readings are created like SBFSpot-style
- suppressSleep : the sleep mode (after sunset, before sunrise) is deactivated and the inverter will be polled continuously.
- showproctime : shows processing time in background and wasted time to retrieve inverter data
- target-susyid : In case of a Multigate the target SUSyID can be defined. If more than one inverter is installed you have to
set the inverter-SUSyID to assign the inverter to the device definition. Default is 0xFFFF, means any SUSyID</li> - target-serial : In case of a Multigate the target Serialnumber can be defined. If more than one inverter is installed you have to
set the inverter-Serialnumber to assign the inverter to the device definition. Default is 0xFFFFFFFF, means any Serialnumber</li> - timeout : setup timeout of inverter data request (default 60s)
