* process "IL", "AR" and "MON"
* discard "BMV" and (unsolicited) History Data
* simplify isDataValid()
* veMpptStruct, veStruct: new, verbose variable names, including units,
and replace floats (save values with original integer precision)
* comment on rollover situation in isDataValid()
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.
