Problem with Function grp.update - manos@dynamitec - 23.01.2019
Hello,
I am having a problem with the function grp.update in the latest firmware version. I am using the following script:
lux300 = grp.getvalue('0/6/3')
lux500 = grp.getvalue('0/7/3')
if lux300 == true then
grp.write('5/0/3/', 300)
os.sleep(0.2)
grp.update('0/6/3', false)
grp.update('0/7/3', false)
elseif lux500 == true then
grp.write('5/0/3/', 500)
os.sleep(0.2)
grp.update('0/7/3', false)
grp.update('0/6/3', false)
end
When the script is executed the G.A. 0/6/3 and 0/7/3 are sent to the knx bus and I just want to update the value internaly.
What I am trying to do is to write two different values on the same G.A. when input G.A. 1 or 2 comes with ON on the knx bus. The two input G.A.s have the same tag so that whatever comes first to trigger the execution of the script.
Is this correct or is there a better way to do it? And why is the grp.update function writes the value to the knx bus?
Regards,

If you are connected to LM via ETS the telegrams from grp.update will show there. Can you explain why do you need to reset object values?

is the 0/6/3 and 0/7/3 is used by any knx device ? (trough read exemple)
if no, you can use virtual knx adress like 40/6/3 & 40/7/3

I used also other IP/Router to monitor and I am still getting the values into the KNX. I want to reset them because these two G.A.s is coming with ON from a KNX button and I if 0/6/3 comes 1st with ON and then 0/7/3 with ON the script will send the value 300 and 500 into the KNX bus. So I just want to avoid of having two different scripts.
The function is simple whenever G.A. 'A' comes with ON send Y=300. And whenever G.A. 'B' comes with ON send Y=500.

Hello Demeur,
I know this but I want to avoid the extra time to create the Virtual G.A.s because it will be for many rooms.
