💬 Power Meter Pulse Sensor

[mikeS]

I built this node but it doesn't seem to work. It shows up in the hardware list of my controller (Domoticz latest stable) as S_Power but no values appear like I was expecting V_WATT, V_KWH etc. Nothing appears under the devices section. Does the sketch need modifying for 2.0 or is it a Domoticz issue? Anybody else got one of these working?

@mikeS has the sensor sent any values? Domotics does not show anything until the first value has been sent.
Could you post the log from the sensor and the gateway?

[mikeS]

Sorry please disregard, I got it working, the pot just needed trimming down, it was permanently triggered so not reading pulses. It worked straight away as soon as I did that. I thought the green light on the lm393 was a power indicator as it was always on, not pulsing.

@mikeS great work, thanks for reporting back

Like all the nodes and the project in general, it's amazing, but in the space of 24hrs I have turned into a "turn everything off" sort of a guy. I cringed when I suddenly had a log of how much money I was wasting! One thing that's weird is that Domoticz shows 2 devices; usage and meter, the usage one doesn't update at all, but the meter one displays everything you need anyway. It's a bit like the DHT node, in that they show as 3 devices TempHum combined which update nicely; and 2x LacrosseTX which update randomly.

I do not understand. My boiler is 3KW. https://1drv.ms/i/s!AtuQgBKT8NIPhi4F_I3mPVYW0S9P

@Fat-Fly
I think something is wrong in your code.

Is the pulse setup correct?

[miljume]

Can someone please explain how the sleep mode works?

My sensor works like a charm when sleep mode is "false" but when changing to "true" i get nothing to the GW

Exactly the same setup, the only thing I changed is from "false" to "true"

@miljume
Use sleep mode if you have battery for the node.

Maybe it need lots of Kwh before sending new data. If you don't use sleep mode it will send watt more often.

[miljume]

@flopp Yes, that was my intention

But I wonder how often the sensor send data to the gateway in that mode i.e. how the mechanism works

I might not have waited long enough but it would be good to know what "long enough" is

[flopp]

it need to change 0,02 kWh before sending new value

@flopp Thanks for the link but I still cant get anything in sleep mode

Now I have waited for over an hour with simulated blinks approx twice/second but so far the device havent reported one single time!

By the way, does anyone know how to reset the value stored in the GW?

After some testing the value get's quite high :smiley:

Hi. I built this sensor and loaded the example. It appears the sensor registers with my serial gateway and appears in domoticz. The problem is it hasn't updated the value in 24h? Any ideas?
Thanks

@asgardro
What does the serial output in arduino says?

[asgardro]

In the end it displays the watt value and then just hangs. I haven't modified the example at all. I am @ work now but will be able to check again later

[asgardro]

Came back from work and checked. it is sending to the gateway the first value and gets displayed in domoticz. then dead.. it appears it does not get the pulse count from the gateway respectively from domoticz. has anyone got this working with domoticz?

@asgardro
I am using two of these to DZ.
One has been working perfect for 1,5 month the second I had some problem with initialize after 3 weeks.

[asgardro]

would you mind please sharing the sketch? i don't know whats wrong. i even forced it with "bool pcReceived = false" puting it to true. thanks

[asgardro]

i do not get Serial.print("Received last pulse count from gw:"); in serial output
