avoid staleness in case the same power limit is calculated over and over
again, hence no new power limit value is calculated and hence no power
limit command is sent to the inverter. staleness occurs in this case if
the first power limit command to establish the respective limit was not
received by the inverter. one can easily simulate a situation where the
same power limit is caluclated over and over again: with a battery above
the start threshold, set a very low upper power limit for the inverter
(DPL setting). that value will be used as the limit as long as the power
meter reading is larger than that.
we could also check the limit reported by the inverter. however, that
value is in percent of the inverter's max AC output, and is often not
the same value as we requested as the limit, but slightly off. we then
would have to decide how much deviation is okay, which is unreasonably
complicated.
closes#478.
* DPL MQTT handler: modernize
* there is no need to tokenize and check the topic of a received MQTT
message if we only subscribe to a single topic. all messages will be
for that topic. avoid testing the topic in the callback alltogether.
* use std::string and std::stoi over allocating and deleting a buffer
and copying charactes around.
* use a switch statement to process the actual payload.
* break a long line.
* DPL: fix getMode() return value
getMode() returned a bool. probably its return type was not adjusted
when the third mode was introduced. this lead to mode 2 being cast to
true implicitly, which in turn was used to construct a String, such that
"1" was published as the DPL mode when in fact it was 2.
make the mode an enum class to avoid such problems in the future.
inline getMode() and setMode().
fix indention.
* DPL: improve verbose logging
* shorten DPL log prefix
* canUseDirectSolarPower() was printed two times
* _batteryDischargeEnabled was printed two times
* convert boolean values to human-readable strings
* add units where possible
* split messages into block "before calculating new limit" and "after
calculating new limit", as the latter cannot rely on _inverter being
available.
* order messages such that variables whose value is derived from other
variables are printed later than their dependencies.
* merge output into blocks (one instance near "Printout some stats")
* remove more redundant info (produced in functions outside loop())
* print target grid consumption
* DPL: inhibit solar passthrough while stop threshold reached
* DPL: implement and use isBelowStopThreshold()
we only want to inhibit solar passthrough if the SoC is *below* the stop
threshold, not if it is equal to the stop threshold. otherwise, when
discharging, we would discharge until the battery reached the stop
threshold, then we would also inhibit solar passthrough, until the
battery is charged to the SoC stop threshold plus one percent.
* DPL: implement verbose logging switch
* MQTT: implement verbose logging switch
* power meter: implement verbose logging switch
* Hoymiles lib: implement verbose logging switch
* cpp linting: "final" makes "virtual" and "override" redundant
... however, using only "final" is not as verbose.
if the new calculated power limit is below the minimum power limit
setting, the inverter is shut down. the shutdown() function is called
every time this condition is detected, which is also true if the
inverter is kept shut down for longer. that happens while the battery
is charging in particular (solar passthrough off). there are other
cases.
in such cases we still want to get into the DPL status "stable". to be
able to determine this stable state, we must know if the call to
shutdown did actually initiate a shutdown or if the inverter is already
shut down.
we then can forward this "changed" or "not changed" info up the call
chain, where the loop() will know that the system is actually stable.
* DPL: wait for valid time information
we know that the Hoymiles library refuses to send any message to any
inverter until the system has valid time information. until then we can
do nothing, not even shutdown the inverter.
* DPL: wait for device info to be ready
a calculated power limit will always be limited to the reported
device's max power. that upper limit is only known after the first
DevInfoSimpleCommand succeeded. wait for that information to be
available.
* DPL: fix initial calculcation backoff
if the calculation backoff is initialized to zero, the backoff will be
doubled to zero until a new, different power limit was calculated for
the first time. this lead to the DPL recalculating a power limit
hundreds of times without a backoff after startup.
a new status is needed to communicate that no update was sent to the
inverter because its power limit is still valid. in this case,
calculating a new power limit is delayed by an exponentially increasing
backoff. the maximum backoff time is ~1s, which is still plenty fast.
the backoff is actually necessary for another reason: at least
currently, a lot of debug messages are printed to the console. printing
all that information in every DPL loop() is too much.
the unconditional solar passthrough mode, configured using MQTT, works
differently than the normal mode of operation. it is also independent
from the power meter reading. if this mode is active, a shortcut is
taken to a function that implements the actions for this mode. this is
convenient since we don't have to consider special cases in the code
that handles normal mode of operation.
the DPL already took care to shut down the inverter if anything fishy
was going on, mainly to make sure that the battery is not drained.
however, some cases were missed:
* if the configuration changed such that another inverter is now
targeted, the one the DPL controlled previously was not shut down.
* if the configuration changed such that another inverter (different
serial number) was configured at the same index, the previous one
was not shut down.
this change corrects these problems by making the DPL keep a copy of the
shared_ptr to the inverter. the shared_ptr is only released once the DPL
shut the respective inverter down.
this implementation checks all requirements for a new power limit to be
calculated, one after the other. if any requirement is not met, a
respective status is announced.
status messages are communicated on the (serial) console. these can also
be displayed easily on the web app in the future. the status texts
explain clearly what the DPL is currently doing, which aids
understanding how the DPL works. the status is only announced if it
changes, or after a fixed interval.
as each requirement is checked individually, the code readability is
improved as well. previously, all the respective conditions had to be
checked as well, but the statements were more complex.
the DPL loop is now executed with high frequency, i.e., it does not wait
for a fixed timespan to pass before checking requirements. it always
aborts on the first unmet requirement. this should improve responsiveness,
as the DPL checks all requirements more often.
the DPL now waits for all power commands and power limit updates to
complete. when that is the case, a settling time elapses. after the
settling phase, the DPL waits for a new update from the inverter and
from the power meter. now it can be assumed that the values are in sync.
it then makes sense to calculate a new power limit immediately, which
the DPL then does.
there is no need to assume and hardcode a fixed efficiency for the
Victron solar charger. the charger reports the voltage and current at
its battery terminal, which can be used to calculate the charger's
actual power output.
the fallback to 100% for the efficiency of the Hoymiles inverter, in
case it is not producing power, is too optimistic. this commit proposes
to use 96.7% as the efficiency for that case, which is the peak
efficiency for many (all?) Hoymiles inverters as per datasheet. that
value should be closer to the real efficiency that will be achieved once
the inverter is turned on.
* Power limiter: Use the actual AC power for limit calculation
instead of the last set limit.
In order support setups without battery connected (sources that don't exhaust the limit)
