💬 Water Meter Pulse Sensor
-
Any one used this approach? From the text I see that the node sleeps! How does it measures the consumption if the node is sleeping?
Thank you

@mfalkvidd hello!
I was referring to this statement in the site:
"Use this mode if you power the sensor with a battery. In this mode the sensor will sleep most of the time and only report the cumulative water volume."
Thank you
-
That is nice! But I would have to test it out! Probably that would make the node all the time awake during a long bath! Ok, it would not use the radio all the time, but I would like to know who that would affect the battery!
Thank you all for the feedback

@flopp Did you ever manage to stabilize the readings? Am I understanding you correctly that the readings were fine but the transmission got the reading scrambled?
Did you try to find a magnetic field with the meter instead? I have a similar meter and I'm wondering how best to approach the problem. I've seen people hook up Raspberries and cameras to do OCR basically but that seems like way too complex for an easy problem.

I have not had good results using TCRT5000 IR sensor, did you?
@bjornhallberg well I still think this is the best approach to use RPI + OCRhttps://forum.mysensors.org/topic/1594/automatic-water-meter-reading-with-a-webcam

While looking into the water meter I realized that we are getting a "smart" meter replacement soon. I'll see if I can speed up the replacement schedule. Anyhow, the replacement is a Kamstrup Multical 21 (https://www.kamstrup.com/en-en/water-solutions/water-meters/multical-21) which has several options for reading:
- Requesting the data via optical interface?
- Enabling the pulse function via optical interface, and then reading the IR pulse at 1imp/10lit.
- Reading the wireless mbus signal? (e.g. https://github.com/weetmuts/wmbusmeters)

@bjornhallberg Suggest you discuss with your water supplier, and see what THEY intend to deploy for comms and explain what your own objectives are, that may refine what you are looking at, and they MIGHT actually help rather than be play "stupid" which is unfortunately common nowadays. In all probability they will be looking at wireless m-bus for drive-by readings, this is the predominant method of retrieval.
I admit to surprise at them deploying ultrasonics, they are on the expensive end of the market but they are extremely reliable and accurate. -

I didn’t get it to work.
I was so lucky that my water company change the meter to a meter with wireless m-bus.
So I bought a box for this and now I have 100% correct readings. -

@zboblamont
In Sweden you need a certified installer to exchange your pipes, else in case of water damage your insurance won't cover.
so cheapest for me is a RPI with camera - but yes I would prefer a "real" measuring from a dedicated sensor -

For sure some loss adjusters will use any excuse, but really?
To clarify, in many countries a certified inspector or Engineer must certify that work is carried out within the regulations, it does not state that HE/SHE has carried out the work, only that it has been inspected and verified as compliant. You know any certified local plumbers with 5 minutes to spare, because that is how long it takes me to fit one, and about the time it takes a certified pipe-jockey to verify it's right and sign it off, if it really concerns you ?I have 2 self fitted water meters with sensors, gas meter sensor etc, and a huge amount of DIY stuff any smartass insurer could IMPLY was a contributory factor to the disaster which befell my house, but frankly it wouldn't stand 1 second in Court before being laughed out...
Place hasn't burned down yet, fallen over in earthquakes, or been subjected to landslide, but luckily I don't have Swedish Insurers.... ;)
PS- I should clarify that the standing regulations are framed to quite rightly protect consumers as well as the service provider against cowboys interfering with apparatus. Changing light switches or sockets falls under the same overall umbrella despite everyone and their mother changing them. -

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.

@fredswed And by extension (Possibly Swedish water suppliers differ from UK or Romanian counterparts?) the data retrieved from their devices is often regarded as their property also, and brick walls begin to appear ino what should be readily shared data. If they will not share, fitting a downstream device within your own control can often be the only solution, don't interfere, augment...
As a perverse example, my own gas and electricity suppliers are the German monolith EON who provide and enable access to their 'graphs' online, updated with 1 or 2 month readings (gas and electricity).
Having checked the base data for their graphs, I realised they were presenting a lovely graph based on complete bunkum, and developed and maintained my own ever since, which IS accurate. I checked recently and their graphs are still pretty but complete rubbish.
Installing a gas meter sensor caused EON palpitations until they realised it was the commercial device for the meter and could not object on technicalities then quietly dropped objections, I don't care how they respond when I fit meters to the Consumer box, it is nowhere near their SMART meter which tells me nothing but tells them much, mainly that I halved their 2 monthly bill ;) .
If the service provider will allow detailed sharing of YOUR data, all good and well as it is mutually beneficial, but if not, easy enough to solve at your own expense.
I fitted two replacement upgraded radiators in the last month, somewhere a Romanian regulation lurks that I should not have done so, but the insurer doesn't give a damn unless it is found to have caused the demise of the insured property.. Is it worth the risk? Hell yes... -
It looks very interesting. I complied and uploaded successful, but it ran without run the loop function at all. infrared sensor lighted up but no print out attached Serial.print.

Sorry to hijack the thread a bit,
I'm using a TCRT5000 sensor to read a water meter (Zenner), it works ok until it stops detecting pulses, I have to increase the sensitivity (clockwise turn the trimpot) and it works ok for another few days/weeks, then again it needs an increase in sensitivity, like somehow it's loosing it's sensitivity .
I'm already with my second sensor, the first one got to the end of the trimpot and couldn't adjust anymore.Has this happened to anyone else? It's powered by 5V, it's the LED losing power or the photosensor losing sensitivity? Any ideas?
Thanks.
