Sampling rate for blockly scripts

[Adso76]

Hi,
Is it possible to change sampling rate for script? I have a script (blockly) which detects whether a physical button is pressed and alternatively turns on and off the device. It works but you need to hold the button pressed for half a second to get a reaction, which is annoying.
When I wrote the same logic in external Python scripts, which detects the button and sends a signal via JSON to domoticz, the reaction is without any delay. Is there a solution?

What kind of communication is there between the button and domoticz ? RFLink, Zwave, MQTT, other ?

The communication is wire I just connect one of the pins of PCF8574 with GND.

I assume you use a GPIO pin for that? Is there software de-bouncing involved of the GPIO pin? That could explain the delay

So how you explain that external Python script, which detects the button and sends a signal via JSON to domoticz works ok (the reaction is without any delay). IMHO, the problem is somewhere within domoticz.

Without knowing how the Python script looks like, i assume you read the GPIO pin directly without de-bouncing the input. Normally when you connect a switch to a GPIO port, you need to de-bounce the input from generating multiple state changes (search Google for that). Then there is a delay involved.

Code: Select all

PCF8574=0x20

b=smbus.SMBus(1)

b.write_byte(PCF8574, 0xff)
state = 0

pins = b.read_byte(PCF8574)
prev_pin = pins & 0x01

while True:
	pins = b.read_byte(PCF8574)
	pin = pins & 0x01
	if pin == 0 and prev_pin == 1:
		if state:
			state = 0
			httpresponse = urllib.urlopen("http://192.168.1.200:8080/json.htm?type=command&param=switchlight&idx=20&switchcmd=Off")
			time.sleep(0.3)
			httpresponse = urllib.urlopen("http://192.168.1.200:8080/json.htm?type=command&param=switchlight&idx=8&switchcmd=Off")
		else:
			state = 1
			httpresponse = urllib.urlopen("http://192.168.1.200:8080/json.htm?type=command&param=switchlight&idx=20&switchcmd=On")
			time.sleep(0.3)
			httpresponse = urllib.urlopen("http://192.168.1.200:8080/json.htm&type=command&param=switchlight&idx=8&switchcmd=Off")

And blockly looks like this:
