💬 Water Meter Pulse Sensor
-
Water Meter shows up in mysensors.json and homeassistant logs but fails to appear in Homeassistant GUI.
I have a dozen Nodes already successfully operating
I used the default sketch on this page. Just added Node 6
Looks like values are not getting through
Thank you for your help -
this is HA log:

Is it possible to get any help on this page or not?
Crying out loud most likely will not help...
Seems your setup is a little special, so just some assumptions from one using a serial GW and not MyS-MQTT:
Your controller is asked for sending an initial value, but has none yet. So no answer is sent out. Triggering the counter on Node side could help to send one (after waiting time has passed). Then have a look at your controller, if there's a value available. If, you might set the correct value, restart your node afterwards and see, if everything now works as expected? -

...just let the node count some pulses (your code states: FALLING). So just pull the counter PIN (here: D3) to ground several times.

Logparser states: there was nothing counted (empty payload). So make sure, there really was counted anything.
(I didn't check your sketch, just assuming, it's the default one and everything is wired correctly; if that's the case, you should be able to see a different payload than nothing or "0", that your controller might treat as non existent). -
Great work @bart59 !
Do you have any indication on how long battery life you will get with this setup? -
@mfalkvidd how looks the sensor now with the modifications? and how to wire this?

See https://www.mysensors.org/build/parser: There's a problem in the initialisation of your transceiver (whatever it may be). So first check wiring, see https://forum.mysensors.org/topic/666/read-this-first-it-could-save-you-a-lot-of-time for further details. If that doesn't help, imo you should open up a seperate thread.

I am finally getting around to trying this out. I was playing with just trying to see if i can get the pulses. First thing i did was take an old compass and put it beside the meter and had someone turn on the water. I could definitely see the compass needle pull a little as the water was flowing. So I assumed that pull was enough to be detectable with my hall effect sensor. I have tried a couple, and just can't seem to get it to pick up.
If i use a magnet, simple code will detect the pulse and the green led on the sensor lights up.
But no matter where I put that sensor near the meter it just doesn't seem to detect it. Not quite sure what's happening.
The meter i have is this one.

My sensor I am testing with is
3144E Hall Effect SensorDoesn't have a sensitivity dial but the recommended one on this build page didn't either.

I wanted to operate my water pulse meter on batteries and also get the water flow. The original design had the following issues with that:
- Incorrect flow calc: micros() was used to calculate the flow, however micros() wraps every 70 minutes which looks like a huge flow (which is then discarded in code)
- Volume calc: millis() wraps every 50 days which is not handled correctly either
- Too much current for battery use: The IR LED of the TCRT5000 is always on and the LM393 comparator is also taking a few mA's
- Could not report flow in sleep mode because millis() does not increment on sleep - need to do this based on calculation of total sleep time. We now simply calculate the number of pulses per minute and deduct the flow
- I also had issued with the data transport reliability, so I added error counters (which show up on the Gateway as distance sensors)
- I also wanted to provide a measurement counter to the gateway (that counts up each time a message is sent)
- The sensor will reboot itself when too many errors occur
So I modified the circuit of the IR sensor:
- Assumption that the wheel of the water meter turns slowly (takes at least a few seconds to turn around)
- We will wake up every 500 millisecond to turn on the IR LED connected to PIN 8. Pin 8 also powers the photo transistor that measures the reflection
- I removed the power from the opamp circuit that is linked to the photo transistor
- The voltage from the photo transistor is then read using an analog read on A1. Based on a threshold value we will deduct if the mirror on the water meter is in view
- Pin 7 is connected to a learning switch which will turn the device in a specific mode and the min/max values on A1 are used to calculate the value of the threshold (which is then stored in the EEPROM)
- After 30 seconds in learning mode, the new threshold is established and the LED on Pin 6 will show the actual on/off mirror signals, so you can see the pulses are correctly counted
- switch back the DIP switch on Pin 7 to bring back normal mode
- The circuit also contains the battery voltage sensor circuit (I am using a 1.5V battery and step up circuit). So the resistors used are 470k from + pole of battery to the A0 input and 1 M ohm from A0 to ground

I made some improvements on this sketch. Please review them here: https://github.com/mysensors/MySensors/pull/1540
with these changes you will have:
1 - factory reset
2 - automatic home assistant entities creation
3 - counter correction from home assistant using service notify.mysensors
4 - fixed counter automatically incremented by 1 at each device restart (due to arduino library interrupt bug)
5- other tiny improvements -
I really like the update you did for Home Assistant integration.
But: I do not really understand, how to correctly send the VALUE_TO_ADD.
This is what I tried to add 967.067 m³:
service: notify.mysensors data: message: VALUE_TO_ADD target: text.water_meter_100_2 data: 967067But I just get this error message:
Fehler beim Aufrufen des Diensts notify.mysensors. expected dict for dictionary value @ data['data']. Got NoneThese are my newly found entities:
What is wrong here?

I finally got this to work. Unlike what the description here says, this is how to update the value:
In Home Assistant, go to Developer->Service->YAML mode:service: text.set_value data: value: "967067" target: entity_id: text.water_meter_100_2(change 967067 with the value you want to add to the current counter)
The service "notify.mysensors" seems to be deprecated by Home Assistant.
