Data type

[FatMax]

Code:

-- Gets values
value1 = grp.getvalue('3/3/0')
value2 = grp.getvalue('3/3/1')
-- Math calculus, is, us, uh
if value1 > value2 then
-- Writes correct value to group address
grp.update('3/3/9', value2)
else
grp.update('3/3/9', value1)
end

I have this script that compares two values and writes the lowest value to a group address. However, I´m not writing it in the correct format. Consequently, the data will not display on screens in the house. ETS does not recognise the data type as a temperature, rather as a 2-byte float.

How do I write a 9.001 Temperature data type to the group?

There's no difference between generic 2-byte float and 9.001 Temperature, you just have to set 3/3/9 object datatype correctly. ETS might not display values correctly for objects that are not in its database.

But a display should display them correctly?

Currently I´m getting 0 °C, although I know I'm sending data to the group address. It should display 10 °C...

You should use grp.write if your display is connected to KNX/TP.

I just changed it to that. Not at site at this moment, however, when I used group monitor (remotely) in ETS it actually showed up there with grp.update. Is that because its connected remotely through the LM?

[admin]

ETS uses tunneling connection and grp.update forwards telegrams to KNX/IP routing an tunneling by default, unless filtering is enabled.

Gotcha! Thanks!

You were correct - It now functions properly!
