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
double precision floating point numbers are not needed to handle
VE.Direct values. handling double is implemented in software and hence
*much* more resource intensive.
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.
if only a single request was made (switch "Individual HTTP requests per
phase" is off), the user could still enable phase 2 and phase 3 config
and configure a respective JSON path. however, the value was never
extracted from the successful HTTP request for phase 1.
closes#637.
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 method calls the overflowed() method on the respective
DynamicJsonDocument and prints a respective message if not all
data could be added to the DynamicJsonDocument.
in case the user defines the respective pins, an MPPT controller will be
setup and the websocket would previously publish its invalid data even
if no data at all was received. this lead to using an invalid index and
to publish a useless card. instead, skip those controllers.
if the connection to a controller breaks, it will always present as a
card in the live view with the respective serial number and the last
known data.
PLLIMIT would not (always) be part of the JSON string transmitted to the
web application and trip it. with the help of the ArduinoJson assistant,
new values to use in the response size calculation were introduced.
also, importantly, a constant offset was added for the DPL status and
the JSON structure sourrounding the MPPTs.
* updating the SoC or value shall also update the general timestamp, as
the latter is defined as "any value changed", which includes SoC and
voltage, of course.
* if the last update is not a valid timestamp at all, the
updateAvailable method must always return false, obviously.
on the "main" live data websocket this can happen if no
OnBattery-specific data is available to sent but the empty
JSON document is still sent, which trips the web application.
publishing null in the battery live data websocket also trips the web
application, which rightfully assumes a valid object if data is received
through the websocket.
determine the amount of controllers actually in use dynamically,
especially to avoid indices which are invalid, causing an error
to be printed, even though the user did not do anything wrong.
in your pin_mapping.json, add a powermeter object like this:
[
{
"name": "My Board",
...
"powermeter": {
"rx": <num>,
"tx": <num>,
"dere": <num>
},
...
}
]
the SML power meter requires the rx pin to be set. the SDM power meter
requires the rx and tx pins are set. the "dere" pin pin is optional and
if set, this pin controls the driver enable and receiver enable pins of
the RS485 transceiver. the SDM library handles this pin.
closes#771.
* remove/comment unused variables to avoid compiler warnings
* cleanups: fix indention and style, make variable private, implement
getters in header and make const.
* optimize message output: respect verbose logging setting. prefix
output with SMA_HM.
* use newly introduced mutex in PowerMeterClass also for SMA HomeManager
* refactor code for readibility, unindent where possible.
the SDM power meter (among others) writes the power consumption of three
phases in multiple steps. this change helps to prevent getTotalPower()
reading intermediate values, e.g., reading a new value for phase 1 but
old values for phase 2 and 3 since phase 2 is currently read.
cache the values, and write them all at once, protected by a mutex,
later.
closes#732.
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.
now that users can tell the DPL that their inverter is not powered by a
battery but powered by solar panels, we shall not restart inverters to
reset the daily yield value, if they are solar powered. these inverters
will reboot every night by themselves.
* fix logic in HomeAssistent handler
* also publish voltage thresholds (not just SoC thresholds)
* do not publish irrelevant thresholds to MQTT. if the inverter is
solar-powered, no thresholds are effectively in use by the DPL and it
therefore makes no sense to publish them to the broker. similarly, if
no battery interface is enabled or the SoC values are set to be
ignored, the SoC thresholds are effectively not in use and will not be
published to the broker.
* make HA auto-discovery expire. this makes auto-dicovered items
disappear from Home Assistent if their value is no longer updated.
changes to settings which cause other thresholds to be relevant will
then be reflected in Home Assistent even if some thresholds are no
longer maintaned in MQTT.
* force HA update when related settings change enabling VE.Direct shall
trigger an update since solar passthrough thresholds become relevant.
similarly, enabling the battery interface makes SoC thresholds become
relevant. there are more settings in the power limiter that also
influence the auto-discoverable items.
* break very long lines
the allocated memory to create the JSON with onBattery-specific totals
for the live view was too little to contain all values, which are sent
regularly.
avoid shutting down the inverter at all if the calculated power limit
falls below the lower power limit or if the power meter value is
outdated. do this only if the inverter is setup to be solar powered.
by default and until this change, we assumed that the inverter
controlled by the DPL is powered by a battery. not all users have a
battery in their system. they still use the DPL to achieve net-zero
export. those users can now tell the DPL that their inverter is powered
by solar modules rather than a battery and the DPL will behave
accordingly.
