this new class uses the newly introduced HttpRequestConfig and performs
HTTP requests using this config. it will be reused for other power
meters (SML over HTTP(S)) and may be reused by other features in the
future (battery provider, solar power provider, etc.).
the extractUrlComponents method did extract username and password
from the URL and encoded it for basic authentication. however, the
respective result string was never used. we only perform basic
authentication if the auth type is "basic" and if username and
password were supplied through the respective inputs.
the parameters to peform an HTTP request by the HTTP(S)+JSON power meter
have been generalized by introducing a new config struct. this is now
used for all values which the HTTP(S)+JSON power meter can retrieve, and
also used by the HTTP+SML power meter implementation. we anticipate that
other feature will use this config as well.
generalizing also allows to share serialization and deserialization
methods in the configuration handler and the web API handler, leading to
de-duplication of code and reduced flash memory usage.
a new web UI component is implemented to manage a set of HTTP request
settings.
avoid additional conversions and avoid double for the fact that
calculations on type double are implemented in software, whereas
float is handled in hardware on ESP32.
this new class handles SML data. it uses the SML lib to decode values
and manages those. this de-duplicates code as the class is applicable
to all power meters that collect SML data.
this setting was not used. the baud rate for the SDM is set to 9600 in
the source code. until the baud rate being customizable is actually
required by somebody, we remove the setting altogether.
"powertotal" is always published and it is published by the base class
directly. other values are still published by the derived classes, but
use a base class method, which takes care that a common base topic is
used in particular.
instead of iterating a map with subscriptions, we now bind the target
variable to the callback, which is executed once a message is arrived.
this way, the target variable is already linked to the respective topic
when the callback is executed.
lock the mutex when writing the variable, as the MQTT callback is
executed in a different context (MQTT task) than the main loop task,
which otherwise accesses the variables.
it is important to separate the capabilities of each power meter
provider into their own class/source file, as the providers work
fundamentally different and their implementations must not be
intermangled, which made maintenance and improvements a nightmare
in the past.
this only changes line endings. inspect this commit with command `git
show <commit-sha> --ignore-space-at-eol` and it will tell you that the
commit appears to be "empty" (since all changes are whitespace changes
near the end of a line, which are ignored in that git show command).
the files to be changed were found and updated using this command:
find lib src include webapp/src -type f | \
xargs grep --binary-files=without-match --files-with-matches \
$(printf '\r\n') | xargs dos2unix
the following files were restored afterwards, as they are using CRLF
line endings in the upstream as well:
- lib/CMT2300a/cmt2300a_defs.h
- lib/README
- include/README
this updates the partition scheme for devices with 4 MB of flash memory
to have only a single app partition, doubling its size, but sacrificing
their OTA update capability. the replacement environment for
"generic_esop32" is called "generic_esp32_4mb_no_ota".
the new default partition scheme is targeted for devices with at least 8
MB of flash memory. the previous two app partitions are merged into one,
and one additional app partition of the same new size is added to the
back of the table. the change preserves the littlefs partition (position
and size), allowing for upgrades without loosing the configuration.
another new environment is added, called "generic_esp32_8mb", which uses
the new default partition layout.
environment "generic" is removed. it was merely a variant of
"generic_esp32" with some pins pre-defined. we want users to install a
pin_mapping.json and use the generic firmwares.
environments for boards that have no version with at least 8 MB of flash
memory are setup using the 4 MB partition layout (no OTA updates).
all users must flash the factory.bin for their respective environment
using esptool (or compatible software) using the USB port of their
board. in other words: updating to the new partition scheme using an OTA
update is NOT possible.
hint: the ESP32-S3 builds have a smaller code footprint. this means
ESP32-S3 boards can be updated using OTA without updating the partition
layout on the devices for some unspecified time longer, i.e., until
their firmware binary actually becomes too large for the old sketch
partition size.
the non-factory binary for generic_esp32_4mb_no_ota is NOT collected as
an artifact. going forward, users must update using the factory binary
and using the USB connection to their boards.
these fail due to the overflowing sketch partition. we can re-enable CI
build for these environments once we decided on how to handle ESP32 with
only 4MB of flash.
the "serial console" over USB would be garbled badly after switching to
"platform = espressif32@6.7.0". this did not happen to the upstream
version of MessageOutput. we used Serial.flush(), which seemed to be
good in the respective context. however, the changes in
github.com/espressif/arduino-esp32/pull/9462
made flush() detrimental. we remove the use of flush(), as it seems not
to be required (in particular, the upstream project does not use it).
broke in be41e6b9. was unusable as the complete type of DummySerial has
to be available in the JK BMS controller header when defining the
unique_ptr managing the dummy instance. this problem is solved by moving
the whole dummy class into its own header.
all total cards at the top of the live view go into the same row.
bootstrap will line-break after every third column/card, as the row
is row-cols-3.
the battery icon to the right of the project name in the header shall
have marging to said project name.
the rows in the live view now use class mt-0 to counteract bootstraps
negative margin for individual rows.
instead of hard-coding the use of hardware UART 2, the SDM power meter
instance now asks for a free hardware serial port to use and
instanciates the respective HardwareSerial object using said port.
get rid of particular compile-time designations by UART index. just hand
out the next free index of hardware UARTs, or indicate that none is
available any more.
use names as keys to register and free UARTs.
only on ESP32-S3-USB. this fiddles with the available hardware UARTs to
make it possible to use a third Victron MPPT. if three MPPTs are defined
int the pin mapping, you will not be able to use the SmartShunt and JK
BMS battery interfaces.
note that using a second MPPT will also conflict with the SDM power
meter, and that conflict is not detected, yet.
