b299b9dc6c VE.Direct: simplify access to data
hand out const& to the data structs. this is possible now that this
struct is "stable", i.e., not reset regularly.

ad125ea804 Fix: properly handle fragmented VE.Direct messages
queue every text event until the frame was checked by it checksum. then
process the data directly into the buffer struct. do not clear the
buffer struct, so it will always include the most recent value of a
particular data point.

use frozen::string and frozen::map where reasonable (#593)
this change utilizes some of the features from library "frozen", which
was included upstream for the grid profile parser. to improve code
maintainability, a couple of std::maps mapping strings to values or the
other way around were introduced in OpenDTU-OnBattery-specific code at
the expense of some flash and computing overhead.

library "frozen" offers constexpr versions of map and string, which
saves initialization code and offers slightly faster lookups. this
brings the binary size down by ~25kB and should provide a small
performance improvement at runtime.

VE.Direct: Fix design issues and prepare support for multiple instances (#505)
* introduce VictronMpptClass

this solves a design issue where the loop() method of a static instance
of VeDirectMpptController, which is part of library code, is called as
part of the main loop() implementation. that is a problem because the
call to this loop() must be handled differently from all other calls:
the lib does not know whether or not the feature is enabled at all.
also, the instance would not be initialized when enabling the feature
during normal operation. that would even lead to a nullptr exception
since the pointer to the serial implementation is still uninitialized.

this new intermediate class is implemented with the support for multiple
Victron charge controllers in mind. adding support for more charge
controllers should be more viable than ever.

fixes #481.

related to #397 #129.

* VE.Direct: move get.*AsString methods to respective structs

those structs, which hold the data to be translated into strings, know
best how to translate them. this change also simplifies access to those
translation, as no parameter must be handed to the respective methods:
they now act upon the data of the instance they are called for. adds
constness to those methods.

* VE.Direct: simplify and clean up get.*AsString methods

use a map, which is much easier to maintain and which reads much easier.
move the strings to flash memory to save RAM.

* DPL: use VictronMpptClass::getPowerOutputWatts method

remove redundant calculation of output power from DPL. consider
separation of concern: VictronMpptClass will provide the total solar
output power. the DPL shall not concern itself about how that value is
calculated and it certainly should be unaware about how many MPPT charge
controllers there actually are.

* VE.Direct: avoid shadowing struct member "P"

P was part of the base struct for both MPPT and SmartShunt controller.
however, P was also part of the SmartShunt controller data struct,
shadowing the member in the base struct.

since P has slightly different meaning in MPPT versus SmartShunt, and
since P is calculated for MPPT controllers but read from SmartShunts, P
now lives in both derived structs, but not in the base struct.

* VE.Direct: isDataValid(): avoid copying data structs

pass a const reference to the base class implementation of isDataValid()
rather than a copy of the whole struct.

* VE.Direct: unify logging of text events

* VE.Direct: stop processing text event if handled by base

in case the base class processed a text event, do not try to match it
against values that are only valid in the derived class -- none will
match.

* VE.Direct MPPT: manage data in a shared_ptr

instead of handing out a reference to a struct which is part of a class
instance that may disappear, e.g., on a config change, we now manage the
lifetime of said data structure using a shared_ptr and hand out copies
of that shared_ptr. this makes sure that users have a valid copy of the
data as long as they hold the shared_ptr.

* VE.Direct MPPT: implement getDataAgeMillis()

this works even if millis() wraps around.

* VE.Direct: process frame end event only for valid frames

save a parameters, save a level of indention, save a function call for
invalid frames.

Integration of Victron SmartShunt via VE.Direct (#452)
* Move Mppt logic to subclass

* Added Definitions for Shunts and restructering

* First integration of SmartShunt data into Web Interface

* Code cleanup

* VE.Direct: whitespace cleanup

* VE.Direct: manage HardwareSerial in unique_ptr

* VE.Direct: _efficiency is only needed by MPPT

* VE.Direct: keep as many members private as possible

* VE.Direct: use int8_t for pins (as before)

* VictronSmartShunt: _verboseLogging is not used

* VE.Direct: OR (off reason) is MPPT specific

it also applies to Phoenix inverters and Smart BuckBoost, but since
there is no support for those, the code is moved to the MPPT controller.

* Added Shunt alarms to liveview
Changed from double to int for several readings

* Update build.yml to allow manual builds

VE.Direct: Reset state machine on timeout, fix and extend logging (#416)
* VE.Direct: reset state machine on timeout

there will never be a large gap between two bytes of the same frame.
if such a large gap is observed, reset the state machine so it tries
to decode a new frame once more data arrives.

this is helpful in case of corrupted data that prevents the state
machine of transitioning to the final state even though the VE.Direct
data producer is done sending bytes that belong to the same frame.

* VE.Direct: print problems to MessageOutput

this includes the web console in particular, where many users have
access to while the serial console is not attached or monitored.

* VE.Direct: collect serial input into buffer and print

should help debug issues for users.

* VE.Direct: implement and use verbose logging switch

Fix vedirect polling (#291)
* VE.Direct: remove polling interval

the polling interval was meant to limit the amount of MQTT updates.
however, that is already controlled by the global MQTT publish interval.
the removed interval was instead used to limit polling of the VE.Direct
UART for incoming data.

the Victron device sends data unsolicited. the VeDirectFrameHandler does
not implement any polling mechanism. no data is ever sent to the Victron
device.

what the removed polling interval did was cause a buffer overrun of the
HardwareSerial class, since the incoming data was not processed in time.
so every five seconds, we read a whole valid VE.Direct frame, plus some
old data, which was not a whole frame, leading to VE.Direct error
messages to pop up.

with the polling interval removed, no framing errors are reported, and
instead we gain new data from the charge controller approximately ever
two seconds -- for free.

* VE.Direct: change texts to correct VE.Direct capital letters

* VE.Direct: improve "UpdatesOnly" switch labels

especially since the publish interval setting is gone, the label makes
it hard to comprehend what the switch does. update the texts to better
explain what the switch is used for.

use the same text on the VE.Direct info view.

* VE.Direct: use StatusBadge on info view

there were custom badges to indicate the VE.Direct settings. replace
those by the common StatusBadge to make then look the same as the other
badged on the info views.

VE.Direct live view enhancements (#269)
* add calculated values to VE.Direct data

solar current, battery output power, and the charger's efficiency can be
calculated from the values reported by the charger. the efficiency must
be taken with a grain of salt. it seems that the solar power value and
the battery output voltage/current are not always in sync. for that
reason a moving average is used to smooth out the calculated efficiency
value.

* show calculated VE.Direct values in web live view

order the values and translations similarly for the input and output,
starting with power at the top, then voltage, then current as the last
of these three.

* VE.Direct live view: use 'd' as unit for days

'd' is the SI unit symbol for days and does not need translation, which
is desirable as units are not translated throughout the project.

* refactor VE.Direct live view

* move Dynamic Power Limiter data into its own type.
* split VE.Direct data into three types: "device", "input", and
  "output". hence all input and output values are now ValueObject, which
  allows to iterate over them using a loop without typing issues.
* generate the tables with input and output values using a loop, rather
  than defining each row individually.
* localize numbers using $n (vue method), which fixes switching the
  number format (dot vs. comma) when switching the language.
* use no decimal point for power values (they are integers), three
  decimal points for kWh values (charger only reports two decimal
  places, but three are easier to read since the unit is *kilo* Wh), one
  decimal point for the efficiency, and two for voltage and current.
* update language tokens to avoid mapping JSON keys to language keys
  (use the JSON keys to access the language tokens).
* re-structure language tokes so the brief keys took over from
  VeDirectFrameHandler always make sense (nest into "input" and
  "output").
* order values similarly from top to bottom: power, then voltage, then
  current. this is following the order of the inverters' details.
* group values by type/unit (yield and max. power) and order them
  "newest" to "oldest" from top to bottom.
* increase the DynamicJsonDocument as it was too small to hold the newly
  added data.

* update webapp_dist to include VE.Direct live view refactoring
