blocks random switch on and off

[Gianni]

i try this blocky to control the temp en humidity of my kitchen.
It need only work from 7 tot 22h but i test the blocky without the time because it's even not work now
it's random switch on and off (within the range) so sometimes the fan turn if it's nod needed or not turn when needed.

Gianni,

i think you have to work with user variables.
Because now the fan can switch on when the temperature is 19 degrees ore more but at the same time the humudity can drop under 59%, so the fan stops again.

"if temp>19 or hum>60 and (user variable) koeling keuken switch = 0
"do set (user variable) koeling keuken switch = 1
"do set koeling keuken switch = on

else if

"if temp<18 or hum<59 and (user variable) koeling keuken switch = 1
"do set (user variable) koeling keuken switch = 0
"do set koeling keuken switch = off

try and let me know
greetings
Kuifje
