unfortunately, the battery SoC values reported by battery BMSs are
unreliable, at least for some users, or at least without regular
(manual) full charge cycles to calibrate the BMS. it offers great
advantages to connect OpenDTU-OnBattery to a BMS (MQTT publishing of
values, Home Assistent integration, etc.), but previously the users
were then forced to configure the DPL by SoC values.
this change allows to configure the DPL such that SoC values are
ignored. instead, the voltage limits are used to make DPL decisions, as
if no SoC was available in the first place.
the SoC related setting are hidden from the DPL settings view if SoC
values are configured to be ignored.
closes#654.
this implementation avoids the display content jumping the full
screensaver offset from right to left when the modulo operator
wraps. this change makes the display content walk from right to
left as it did walk from left to right.
in case the total production is larger than 1 MWh, i.e., 1000 kWh, the
text on the respective line becomes too large such that it reaches out
of the display when the screensaver is enabled.
this happens on the small and large displays.
this change switches the number format to a float without decimal places
if the total production is larger or equal to 1000 kWh. this saves a dot
and a digit, making the text short enough to fit the display even when
the screensaver moved the display contents as far to the right as it
does.
fix calculation of the text baselines, using getAscent() in favor of
getMaxCharHeight(), which includes ascent and descent. this moves the
first text up and allows to insert margin between the lines until the
display area is fully utilized.
on large displays, if the small diagram is selected, keep the first line
rather low to avoid collision with the diagram y-axis label. in this mode,
there is still more space between the text lines as before, allowing for
improved readability.
* pylontech HA integration: remove unused method/variable
* make MqttHandlePylontechHassClass::publishConfig() private.
there are no outside users of that method.
* rename to MqttHandleBatteryHass
* battery HA integration: merge methods and bring back forceUpdate().
even though the forceUpdate() method was not in use before, it makes
sense to implement it and use it when the battery config changes.
rather than controlling a separate flag, it now changes the _doPublish
flag of the class, which also triggers publishing the device config to
Home Assistant when an MQTT connection problem was detected. since
both situations are now handled similarly, we can merge the loop() and
publishConfig() methods.
* battery: provider specific sensors for HA
* move Battery MQTT loop to BatteryStats
the BatteryStats class should handle the MQTT publishing, including the
interval. for the calculation of a reasonable Home Assistent expiration
value this class now also knows the maximum publish interval.
* JK BMS: fix publishing values for Home Assistent
Home Assistent values expire, because we set them to expire after three
MQTT publish durations. for that reason, we need to re-publish all
values after our self-inflicted full publish interval.
* define JK BMS sensors for Home Assistent
closes#482.
previously, the Pytlontech Home Assistent class implementation had an
init() method, that was never called, as it did nothing. the class
relied on its loop() method being called from the main loop(). after
switching to the TaskScheduler approach, the Pylontech Home Assistent
class init() method was adjusted to register a task that calls the
loop() method periodically. however, the init() method was still not
called.
To reduce the heap usage it is necessary to send the inverters one by one instead of a huge response. A simple call to `/api/livedata/status` returns just some very general information. If detailed inverter information are required the inverter serial number has to appended `?inv=<serial number>`.
The websocket also returns only one inverter at a time. It as to be assembled at client side.
currently the whole SmartShunt data structure is copied to the
BatteryStats instance in every loop, even though the data cannot
possibly have changed. this is quite an expensive task to do in every
loop. this change tracks the last update timestamp and only does the
copy operation if an actual updated data structure was received from
the smart shunt.
this change adds the values of ESP.gteMaxAllocHeap() and
ESP.getMinFreeHead() to the prometheus metrics and the system
information object. the web UI uses these values to diplay the size of
the largest free contiguous block, calculate a rough estimate for the
level of fragmentation, and the maximum usage of heap memory since boot
in absolute and relative amounts.

OpenDTU console gets spammed with "WifiGeneric::hostByName() error when first trying to resolve the hostname via DNS. So reverse order: first try mDNS, if that fails try DNS. Also ensure that https bool is passed correctly to HTTPClient::begin(). Lastly, concatenate strings for building Digest authorization using "+" and not via snprintf.
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.
Added ability to deal with local host names (mDNS), remove use of FirebasedJson to save ~20kB build size, some changes to PowerLimiter to avoid setting new inverter power limits when not needed (=current limit as reported by inverter is within hysteresis)
this battery provider implementation subscribes to a user-configurable
MQTT topic to retrieve the battery SoC value. the value is not
re-published under a different topic. there is no card created in the
web app's live view, since the SoC is already part of the totals at the
top of the live view. that is the only info this battery provider
implements.
closes#293.
relates to #581.
MQTT message callbacks are executed in the MQTT thread context. when
processing topics that control the DPL, we must avoid executing methods
that are not thread-safe. this change binds the methods to be called to
the respective parameters and executes them in the TaskScheduler
context, such that they no longer need to be thread-safe.
* bind the callback to a topic (enum value) such that there is no need
to tokenize the full topic (string) to find out what value is being
processed. tokenizing is expensive.
* get rid of using the config in the callback, which improves
thread-safety since the MQTT callback is running in the MQTT thread.
* prefer C++ method stof to convert MQTT value to a float, which saves
us from using new and delete for a buffer in particular.
* prefer switch statements over if-else-trees.
* split long lines.
* get rid of topic #defines.
* fix indention.

there are more interesting values available to display in the live view.
however, adding them made the list of values very long. this can be
mitigated by using a new column/card, which uses the available screen
space nicely on bigger screens.
this commit re-introduces the changes from #418, which were effectively
reverted with d49481097 (merge commit introducing TaskScheduler).
these adjustments are important to guarantee unmangled log messages and
more importantly, to guarantee that all messages from a particular
component are printed to the web console, which most people use to copy
messages from when reporting issues.
* use dynamic memory to allow handling of arbitrary message lenghts.
* keep a message buffer for every task so no task ever mangles the
message of another task.
* every complete line is written to the serial console and moved to
a line buffer for sending them through the websocket.
* the websocket is always fed complete lines.
* make sure to feed only as many lines as possible to the websocket
handler, so that no lines are dropped.
* lock all MessageOutput state against concurrent access.
* respect HardwareSerial buffer size: the MessageOutput class buffers
whole lines of output printed by any task in order to avoid mangling
of text. that means we hand over full lines to the HardwareSerial
instance, which might be too much in one call to write(buffer, size).
we now check the return value of write(buffer, size) and call the
function again with the part of the message that could not yet be
written by HardwareSerial.
the updateSettings method is called from the web server's context and
therefore accesses _upProvider in a different context than the
TaskScheduler. the lock_guard needs to protect _upProvider.

* add more values to web app live view. this should add all interesting
values for the web app live view. those include important values and
values that change frequently.
* add more interesting JK BMS dummy messages: one has 0% SoC and an
alarm (discharge undervoltage) set. the other has the undertemperature
alarm set.
* add alarms and warnings to live view
* publish alarm and status bits through MQTT individually
* publish cell voltages to MQTT broker

* VE.Direct: return non-nullptr as a fallback
the changed return statement was supposed to return a shared_ptr to a
new and valid MPPT data struct as a fallback. however, it did return a
new shared_ptr that was initialized to nullptr.
* VE.Direct: make liveview total use total MPPT values
this change makes the call to VictronMppt.getData() obsolete, which in
turn will therefore not cause an error message on the console if
VE.Direct (MPPT) is not enabled. this change also takes care that once
multiple VE.Direct MPPT charge controllers are supported, the sums of
the respective total values are used in the web app totals.
