Domoticz

Why would you want something like V_TEMP?

It now relies on the V_VAR1, but start counting the pulses immediately, they will be added as soon at the gw sends the last value

Main reason is to allow for the reading of all sensor values from the controller for usage and display in other sensors (as in the MySensors API) and getting the latest values for starting sensors.
I currently use it to extract the last kWh (Wh) values from Domoticz when starting the W/kWh sensor. Similar like the water flow sensor discussed. I use external JSON calls now to update the Domoticz value. Domoticz does not accept "increments" as input for the kWh values (a least that is what I understand).

I can also think of many cases where a "last know reading" from the controller is needed to continue measurement after replacing a sensor. Wouldn't it be possible to just return the current value/ last value stored?

thanks, Ad

I removed the gateway from Domoticz, installed the latest beta (v2.2336), flashed the code from above link to the watermeter node and added the gateway in Domoticz again.

But.... the sensor isn't added under 'Devices'. It pops up in the log:

Code: Select all

But it is not added Help? Checkbox to allow new devices is turned on btw...

I also measured my sensor, and when the needle is not near, the LED is on and the output is high. When the needle is in front of the sensor, the LED is off and the output signal is low (0V). So the interrupt for my case should not be on rising, but on falling. Will change and try that later this afternoon.

Thats where the 'VAR' variables are for

Edit: Probably has to do something with the kind of interrupt (high/low). I think the node isn't correctly registering it... will try some fiddling around.

Try to enable the serial print-lines, and open the serial port in arduino to see that your node sends messages

I also found out that the output power of the 3.3V line of the Nano is too noisy or so for nRF24L01+ (a lot of 'st=fail' in the serial console)
When powering with an external 3.3V supply it works.

I tried it with 'MYSController' and i can see the data going back and forth. But the node keeps requesting for the intial count. When i send that (with MYSController) it happily starts counting. But it looks like Domoticz doesn't provide this count, so nothing happens and the device doesn't show up.

I don't have the device added under 'Devices' yet, but it also doesn't show up there, so it can't get a initial count value. So i am stuck in kind of a loop now...

		case V_VAR1:
		case V_VAR2:
		case V_VAR3:
		case V_VAR4:
		case V_VAR5:
			//send back a previous stored custom variable
			tmpstr = "";
			GetVar(node_id, child_sensor_id, sub_type, tmpstr);
			SendCommand(node_id, child_sensor_id, message_type, sub_type, tmpstr);
			break;

The VAR types in MySensors are "Custom values" for when nothing else fits. For illustration purpose. This "display/ power sensor" currently reads the power/ temperature and other weather values from Domoticz (by means of python JSON for now ) through the MySensors network and displays it in every location I want.

Have you used the latest sketch?

And the latest beta of domoticz ?

It should send an empty value back, i supposed that would be translated to '0'

Code: Select all

		case V_VAR1:
		case V_VAR2:
		case V_VAR3:
		case V_VAR4:
		case V_VAR5:
			//send back a previous stored custom variable
			tmpstr = "";
			GetVar(node_id, child_sensor_id, sub_type, tmpstr);
			SendCommand(node_id, child_sensor_id, message_type, sub_type, tmpstr);
			break;

Maybe mysensors does not like an empty value, please tell if you are using the latest beta of domoticz, if yes, i will modify domoticz to send '0' back

Like in the original 'EnergyMeterPulseSensor.ino' sketch ?
