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.
we used this library solely to interpret the answer of an HTTP web
server as JSON and find a particular value using a path expression in
the HTTP power meter implementation.
since we ran out of flash memory on non-S3 ESP32, we need to cut some
corners. removing FirebaseJson is the last low-hanging fruit that we
currently know of. we can get rid of it by using ArduinoJson (which is
already integral part of the firmware) and implementing a custom logic
to extract a value based on a path expression.
other than the FirebaseJson path "finder", the new implementation
only knows how to access sub-keys delimited by a forward slash. in
particular, accessing array members is not supported any more. I am
hoping that this is simply not an issue. if so, we will have users
complaining and we can add this functionality in a later release.
merge upstream tag v24.4.12, resolve conflicts (helgeerbe), fix eslint errors (schlimmchen) and adopt new web api method to save code duplication (schlimmchen).
without a power meter configured, the DPL now sets the base load as the
inverter limit if the battery charge allows it. it also takes
solar-passthrough into account, i.e., if the battery is in a charge
cycle but the solar output (Victron MPPT) is significant, the solar
power will be used up until the base load. if the battery reaches the
full solar passthrough threshold, the DPL will match the inverter limit
to the MPPT solar output.
on power meter issues (usually a timeout), keep the inverter enabled and
make it produce the configured base load limit if the battery can be
discharged. that should be okay since the base load config value is
expected to be small and a little less than the actual household base
load, i.e., if this amount of power is produced, the household will
consume it in any case and no energy is fed into the grid.
1. makes the DPL use the power generated by all connected charge
controllers for calculations based on solar passthrough.
2. makes the network total DC power appear as "MPPT Total Power" in the
live view at the top.
3. shows the network total DC power in the VE.Direct live data card.
* show charge controller temperature in live view
* send hex requests right after decoding a frame. this seems to have the
best chance of getting an answer to all requests.
* deem 0xFFFFFFFF value of network total DC power as invalid indicator.
neither network state, nor network info, nor network mode seem to
indicate that the charge controller is part of a VE.Smart network. for
that reason, we revert to always querying the network total DC power
value, but testing it for max(uin32_t) value, which seems to indicate
that the charge controller is not part of a VE.Smart network.
* improve (verbose) logging, e.g., use _logId, and print names of
response codes and known registers, always print error messages,
add additional tests to prevent overly verbose messages.
* move hex protocol definitions to VeDirectData.h header
and use enum classes
* define register addresses in enum class
* move values retrieved through hex protocol into main MPPT data struct
* do not send HEX requests if the serial interface cannot send data
* detect whether smart battery sense temperature is available
* web app: make all VE.Direct sub-cards iterable. this makes addind more
values much simpler and saves a bunch of code in the web app.
* make VeDirectFrameHandler state a type-safe enum class
* unindent MPPT controller loop()
* whitespace cleanup
users are manipulating the DPL using HTTP POST requests. often they are
requesting the current settings using HTTP GET on the respective route,
then change a particular settings, and send all the data back using HTTP
POST. if they failed to remove the metadata node from the JSON,
OpenDTU-OnBattery would not be able to process the JSON due to its size.
the web app does not submit the metadata.
to avoid problems, the metadata is now split from the configuration
data.
this changeset refactors the web application's DPL settings view. the
DPL settings can be complex, and they shall be presented in a way that
allows users to comprehend their meaning. irrelevant settings are now
hidden or displayed dynamically based on the influencing settings.
* group SoC thresholds into their own card
* hide battery SoC thresholds if battery disabled. if the user did not
even enable the battery interface, battery SoC values will not be used
for DPL decisions. in that case we completely hide the respective
settings from the DPL admin view. this reduces the amount of settings
for new users and especially users who don't even have a battery in
their setup or have no BMS connected.
* group voltage thresholds and improve label texts
* fix load correction factor unit
* fix header (wording)
* group solar-passthrough settings in new card
* group inverter-related settings
* hide solar passthrough settings if VE.Direct is disabled. closes#662.
* completely disable form if any requirement is not met
* list available inverters by name and type. this makes it much more
convenient to select the right inverter, especially since the order of
the inverters in the web UI is decoupled from their position in the
internal array, which was used to select them previously. care was
taken that old configs select the same inverter after an update.
when editing the DPL settings, the selects an inverter from the newly
created drow-down list, and the respective old inverter is
pre-selected.
* disable form if no inverter is configured (config alert)
* make inverter input selection dynamic. adjust selection to actual
amount of channels for selected inverter. skip selection altogether if
inverter has only one channel, or if it is solar powered.
* web app: wording adjustments
* group meta data into new property and exclude from submission. saves
memory when evaluating the submitted settings.
* hide irrelevant settings if inverter is solar-powered
* move restart hour setting to inverter card. translate setting which
disabled automatic restart.
* simplify "drain strategy" setting into an on/off toggle. care was
taken that existing configs work the same after an upgrade. the
respective drain strategy is translated into the new setting when
reading the config. once the config is written, the new setting is
persisted and the old is not part of the config any more.
* show more configuration hints, depending on actual configuration
* replace inputs by InputElement components where possible
* fix compiler warning in SerialPortManager.cpp: function must not
return void
* clean up and simplify implementation of usesHwPort2()
* make const
* overrides are final
* default implementation returns false
* implement in header, as the implementation is very simple
* rename PortManager to SerialPortManager. as "PortManager" is too
generic, the static instance of the serial port manager is renamed to
"SerialPortManager". the class is therefore renamed to
SerialPortManagerClass, which is in line with other (static) classes
withing OpenDTU(-OnBattery).
* implement separate data ages for MPPT charge controllers
* make sure MPPT data and live data time out
* do not use invalid data of MPPT controlers for calculations
* add :key binding to v-for iterating over MPPT instances
this change adds support for a second Victron MPPT charge controller
using a second serial connection.
* Add device configuration for a second victron mppt
* Update VedirectView for second victron mppt
* Update MqttHandleVedirect for second victron mppt
* Update MqttHandleVedirectHass for second victron mppt
* Handle nonexisting victron controllers with optionals
* Add bool-function to Battery and inherited classes, if uart port 2 is
being used
* Introduced a serial port manager. In order to prevent the battery and
the Victron MPPT to use the same hw serial ports, this class keeps
track of the used ports and their owners.
the update frequency of Victron MPPT charger data, the battery Soc, the
huawei charger power, and the power meter differ from one another, and
differ in particular from the inverter update frequency.
the OnBattery-specific data is now handled in a new method, outside the
upstream code, which merely call the new function(s). the new function
will update the websocket independently from inverter updates. also, it
adds the respective data if it actually changed since it was last
updated through the websocket.
for the webapp to be able to recover in case of errors, all values are
also written to the websocket with a fixed interval of 10 seconds.
this extends the MqttBattery implementation by an additional topic which
allows to subscribe to receive battery voltage readings through the MQTT
broker. similar to the battery SoC topic, this allows to import a
critical battery data point for the DPL, in case the user chooses to use
voltage thresholds rather than SoC thresholds to control the DPL. if an
otherwise incompatible BMS is available which publishes the battery pack
voltage through MQTT, this can now be used to feed accurate voltage
readings to the DPL.
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.
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.
