@flopp Watt is sent every 20 seconds (as done in the original sketch).
500 watts is the power indicated on the screen of the power meter.

@flopp After a few days, I confirm you that the index is consistent with power meter index.
However, instant power in watt is not correcly calculated.
For example, when power meter indicates 550W, about 1500W is calculated by the sketch. Do you know how I can resolve this problem please ?

Thanks a lot !

@flopp It seems to work, index on Domoticz is still consistent with the real index... I will see in a few days if it's still the case.
Thanks a lot for your help !

@flopp Thanks a lot, I will try this solution and check if it's better !

@gohan No, the light is always switched off in this room and I tried, when I switch on the light, there is no pulse from the sensor.

@flopp Thanks for your help. What I see in your topic is that you increase from 10000µs to 40000µs the interval to avoid corrupted interrupts, is that correct ?

Thank you

Hello,

I don't understand why, but my power meter sensor gives a higher index than the real power meter index after 2 days.
I think that it counts more pulses than pulses provided by the power meter...
Does anybody encounter this problem ?
Can it be cause to bounce for example ?

Thank you

Thanks a lot, it works using V_TEXT instead of V_KWH !

@AWI Thanks a lot for yout answer ! I will try this !

@moumout31 Nobody knows how to help me please ?

Thanks

I tried to debug my sketch but when I request the last know value from gateway request(CHILD_ID_PMPINIT, V_KWH);, I have no answer from the gateway.

Contrary to the MySensors example Power Meter Pulse, after several tries, I've created a new Child in order to store the init value of meter and to be able to update it via json.

You can see the sketch here below.

Thanks for your help.

@sundberg84 Thanks for your help.
It seems to answer my problem, I will try what is done on this topic.

Hello,

I've tried to use the Power Meter Pulse example of MySensors website, but I can't initialize the first kwh value with the current meter index.
Thus, I would like to send the index manually via Domoticz to initialize a variable in the Arduino sketch of the node.

Do you know how I can set a value in Domoticz and send it to a MySensors node to store it in a variable please ?

Thanks in advance for your help.

@mfalkvidd It's strange... It works with an older version of Arduino software... Thus, the problem is solved ! Thanks

@mfalkvidd void receive(const MyMessage &message) is in the code.
MySensors library is installed, I already use it in other nodes.
It's strange because it works in another computer...

The full error messages, in french beacause I'm french are :

Hello,

First, thanks for this tutorial !
I used the code defined in tutorial but I have the following message for "void receive(const MyMessage &message)" :

'MyMessage' does not name a type

Do you know what can be the cause of this error please ?

Thanks in advance for your help

Hello,

I also precise that first I didn't use a level shifter to reduce 5V Arduino to 3,3V for RFM69W pins. Thus when I tried again, I used new RFM69W chips.

Thanks for your answer. For tests the sensor and the gateway are separated by nearly 4m... I tried to move them but it doesn't work.

Hello,

I'm french, so my english might be strange sometimes...

I use RFM69W to communicate between Arduino Nano Serial Gateway and prototype sensor, based on Arduino Duemilanove.
As it's written in the title it doesn't work.

Of course, both have the same MySensors library version (2.1.1, also tested with 2.1.0 and 2.0.0).
47uF capacitor has been added between 3.3V and GND in sensor and gateway.
3.3V is provided by Arduino Nano in gateway and Arduino Duemilanove in sensor.
In order to adapt arduino voltage, an "8 Channel I2C IIC Logic Level Converter Module Bi-Directional for Arduino" bought on eBay is used to convert 5V <=> 3.3V for RFM69W I/O.

I've browsed forum topics find on Google, but nothing works.
Of course, I've started by following the page "Debugging Sensors and the Gateway"

I've just made a strange observation, when I connect the sensor and the gateway on my computer USB, if I connect or disconnect the gateway USB from my computer, the LED "L" on my arduino duemilanove (sensor) blinks several times before recovering its initial state.

Could you help me please ?

If I can give you more informations, do not hesitate.

Thanks in advance for your help !
