Water pulse meter value not reported automatically

fredswed

I've successfully used NodeManager to set up thermo-/hygrometers and the next step is to use it for my water and power meters. However, I'm running into problems.

I have used the template sketch and changed/added very little code:

#define NODEMANAGER_DEBUG OFF       // Default ON
#define NODEMANAGER_SLEEP OFF       // Default ON
   /* snip */
#include <sensors/SensorWaterMeter.h>
SensorWaterMeter waterMeter(2);

The problem is that V_VOLUME is only sent at startup. But not when pulses are counted and the value has changed.

When I request the value manually with a C_REQ message the node reports it twice. First the correct count based on pulse counting and then immediately after 0.0000. (See end of debug log below.)
So it seems the value is reset.

This does not seem like the expected behaviour.
Am I missing something in the configuration or what else could be the problem?

For testing I tried adding a nodeManager.setReportIntervalSeconds(30); but with no success. The node clearly does not report every 30 seconds.

The node is a 3.3V Pro mini (EasyPCB) and I'm using MySensors 2.3.1 and NodeManager 1.8.0 libraries on Platformio/VS Code. Gateway is ESP8266 with MySensors 2.2.
I use MYSController as my testing controller and see the same behaviour in OpenHAB.

@fredswed definitely not the expected behaviour Can you please set NODEMANAGER_DEBUG to ON and share NodeManager's logs as well. This can help me debugging the issue on NodeManager's side.
Only thing I can see from you code is the use of pin 2. If the Pro Mini is using the radio for transmission, that pin is already used by the radio. Try using pin 3. Thanks

fredswed

@user2684 Many thanks - somtimes it is hard to see the obvious! Pin 2 is definitely connected to the radio which is more than likely a problem. Note to self: do not connect keyboard to ethernet port
Have not had the time to fix it and check yet but will do asap.

Btw, Is the reportInterval required, or will the sensor report on every pulse if an interval is not specified?

user2684

@fredswed if not specified, sensor will report every hour (https://github.com/mysensors/NodeManager/blob/master/sensors/SensorPulseMeter.h#L45). The sensor itself will take care of summing up the accumulated value along the timeframe

fredswed

@user2684 Thanks!
Finally had the time to try again. Unfortunately no success. Even worse - I can't find the problem I'd really appreciate any advice on the code or how to troubleshoot.

I changed the pulse pin to 3 and recompiled just before the run.

After startup, pulses were simulated by quickly connecting pin 3 to ground starting at 141883
I expected values to be sent every 30 seconds but none were sent.
I did a C_REQ request at 1452361
Automatic reports were sent from the node around 1 hour (3600000) and 2 hours (7200000), so the reporting interval seems to be at the default 1 hour, not 30 seconds as stated in the code. It's either strange or I have missed something basic...

@fredswed ok looks like the interrupt is intercepted and accumulated value is calculated correctly but the values are just not sent at the specified interval, right? Try calling setReportIntervalSeconds()
on waterMeter rather than nodeManager. When you call nodeManager.setReportIntervalSeconds(30), this is applied to all the sensors with a report interval not set yet. But since SensorPulseMeter already calls setReportIntervalMinutes() I believe NodeManager will skip it. Thanks

fredswed

@user2684 Thanks! Using waterMeter.setReportIntervalSeconds(30); works and values are now reported every 30 seconds as expected.

One problem still persists - the counter seem to be reset and there is always a zero value reported after the true value. E.g. after creating a few pulses, I get the log:

27027 NM:LOOP:WATER(1):SET t=35 v=0.0190

I've digged a bit in the NodeManager code on my own and is far from certain, but isn't it a problem that reset() is called when the value has been reported by the child (line 199)

If I get it correctly:
When waterSensor calls setValue, it in turn calls setValueNumber which adds the pulse to _total. That's fine.
But when sendValue is called at a later time, both _value and _total are reset to 0 as _value_processingis SUM.

So the pulse count will restart from zero.
Wouldn't we want to keep at least _total at its current value, to keep the accumulated number of pulses over time?

user2684

@fredswed thanks for your analysis. I think you hit a bug here,I believe is correct that _total is set to 0 when the value is sent (so to start counting again) but it should not send that 0 value message. Keeping track with https://github.com/mysensors/NodeManager/issues/458

fredswed

@user2684 Thanks! Looking forward to a solution, one pulse at a time

gomba777

@user2684

I'm trying to convert all my existing sensors from the old mysensors code to the nodemanager which is really a great and easy approach. The problem is that on the original mysensors water pulse sensor, the value is not reseted to 0 after each SEND but the total keeps incrementing. So my question is why is it better to reset to 0?

Also on the old water meter, there is a FLOW value and the sensor also try to get the existing value from the controller when starting. Do you think that could be implemented on the Nodemanager version?

fredswed

@gomba777 I have only tried the NodeManager version but am considering the old-style code until it works. I would expect any water meter sensor to at least report accumulated totals, similarly to the physical device. I am sure that can be implemented in NodeManager - it is perfectly possible to use extend the framwork oneself even if it is not in there by default. It is more a question that someone as to put the time into it.
If the other code works for you, I guess the best choice is to hang on to it for a while longer.

user2684

Thanks @fredswed and @gomba777 I've added to the roadmap the capabilities you are referencing to from https://www.mysensors.org/build/pulse_water so the align with NodeManager's. I'll likely come back to you once the development will get to that point for reviewing the implementation if you don't mind. Thanks
