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

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 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:

@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...

@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?

@bjacobse I believe you can replace the meter yourself if you own it yourself and have the necessary skills. I live in such an area and was told I could mount it myself if I was confident enough. But of course, the fault will be yours if your bad job causes damages. In reality it is quite unlikely that you can mount it badly and not notice the problem immediately.

A more critical issue is that water meters are usually owned by the municipality or water company and they are sealed. It is impossible to replace the meter without breaking the seal and when the company notices they won't be happy at all.

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.

@guillermo-schimmel Thanks for your response - I would rather consider the node to be the single physical object that provides one or several capabilities (items). Much the same way the Hue, Trådfri or BigAssFan bindings do it.

I currently use a ESP8266 gateway connected by WiFi. I've tried the MQTT connection but couldn't really see any real benefit. The downside was that it was really hard to troubleshoot in OpenHAB as I needed the old mqtt binding for other stuff. I noted that OH2.4 switched to the new Eclipse MQTT binding so I expect it to be easier to set up MySensors with MQTT in OH2.4 and later.

@benhub I don't have direct experience with the sensors you mention but my general view is in line with @BearWithBeard - results are not always consistent even if you stick to a single sensor brand/type.

This overview gives a good picture of the variation you can expect and some of the difficulties with calibrating humidity sensors on a hobby level.
