Creating sprase image before compressing

1

In order to get smaller compressed image, place allocated by deleted files shall be zeroed. This is called “sparse image”. According to https://ext4.wiki.kernel.org/index.php/Ext4_VM_Images#Good_Tools_for_Making_Sparse_Images:_fstrim.2Fe2fsck.2Fzerofree to create a sparse image one has...

PiShrink uses resize2fs to find the minimal possible size of a partition. resize2fs is not perfect in this: for a partition of 1.7GB data and 650MB free, resize2fs does not...

inverter.cpp: avoid mess with simultaneous read/write operations

1

When many inverter_poller at the same time send commands, the result is undefined. This locks exclusively the configuration file, while the process is running, so that simultaneous instances have to...

Accept the QPI, QID, QVFW, QVFW2, QFLAG, QBOOT, and QOPM commands.

inverter_poller prints not plausible value for Battery_redischarge_voltage

On my system, inverter_poller prints: > "Battery_redischarge_voltage":121388030977618053106918512643666870272.0, This value is not realistic. The complete output is: ``` # inverter_poller -1 { "Inverter_mode":4, "AC_grid_voltage":238.3, "AC_grid_frequency":50.0, "AC_out_voltage":229.6, "AC_out_frequency":49.9, "PV_in_voltage":49.0, "PV_in_current":7.0, "PV_in_watts":345.6, "PV_in_watthour":11.5194,...

The HS_MS_MSX protocol specification in the repository says for the QPIRI command value R is “Parallel max num”. On my system R returns 9, while the source code expected "-"...

Closes: https://github.com/ned-kelly/docker-voltronic-homeassistant/issues/68 Related-To: https://github.com/manio/skymax-demo/issues/10

https://github.com/ned-kelly/docker-voltronic-homeassistant/blob/master/sources/inverter-cli/main.cpp#L90 contains: ```c++ else if(linepart1 == "watt_factor") attemptAddSetting(&wattfactor, linepart2); else if(linepart1 == "watt_factor") attemptAddSetting(&wattfactor, linepart2); ``` This is a tautology, which is fixed in https://github.com/manio/skymax-demo/commit/db91c5f97362572a2d89d25193c7f44b53b7028d .
