💬 Power Meter Pulse Sensor

flopp

@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

flopp

@asgardro
this is my sketch
i use MS 1.5.1

 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * Version 1.0 - Henrik EKblad
 * 
 * DESCRIPTION
 * This sketch provides an example how to implement a distance sensor using HC-SR04 
 * Use this sensor to measure KWH and Watt of your house meeter
 * You need to set the correct pulsefactor of your meeter (blinks per KWH).
 * The sensor starts by fetching current KWH value from gateway.
 * Reports both KWH and Watt back to gateway.
 *
 * Unfortunately millis() won't increment when the Arduino is in 
 * sleepmode. So we cannot make this sensor sleep if we also want 
 * to calculate/report watt-number.

here is my serial output. and remains like this.
i have found your sketch but can not seem to get it to work to gw 2.0

asgardro

flopp

can you please print your code?

I am not so good to read the Message structure but it look like it present temperature and other stuff

asgardro

Ah the gateway works fine with other sensors
The code for the pulse power meter is the one in the example

flopp

@asgardro said:

Yes you do, look at the last line and you will see it.

flopp

@asgardro

change SEND_FREQUENCY to 5000, upload to Arduino, when you see Received from GW, trig Digital Input 3 and after 5 seconds it should send data to DZ again

asgardro

Done that... reset everything..still the same

here is my code

@asgardro
don't forget to use CODE function when posting code.

If you don't see any reaction when you trig Digital 3 i don't know what can be the problem,

Have you tried another Arduino?

flopp

@asgardro

change bool pcReceived to false

asgardro

ooops sorry about that... just found the function lol
the sensor inits itself once and then doesn't do anything/ i don't know through what miracle i got the pulse count.
will try another arduino... i do not think it is a radio problem..
thanks for your help

asgardro

changed it to false.
put it true before to try to force the sensor sending independent of the count.. if i am correct
still the same outcome... will try tomorrow diffrent hardware
anyway, thanks a lot for the help

flopp

@asgardro said:

changed it to false.

Yes it will but it will only send 0 to VAR in DZ so it will be a loop of same value.
Maybe that's why it never sends again.
Try now to trig digital 3
