Taking my first steps with Smartthings integration

Hi
I’m just taking my first steps with Smartthings integrations. I need to control the humidity inside a fridge and am using a Meross humidity montior to measure the humidity. I have a humidifer and dehumidifer inside the fridge, connected to Meross smart plugs. I want to turn the humdifier on (via the smart plug) when the humidity drops below (say) 72% and the dehumdifier on when it rises above (say) 78%. I don’t want both operating at the same time. The pseudo code is

min_humid = 72 // Lowest humidity
max_humid = 78 // Maximum humidity

humid_on = False // Status of humidifier (initially off)
dehmd_on = False // Status of dehumidifer (initially off)

loop over:
// Humidifier setting

if (humid <= max_humid) and not dehmd_on:
    turn_on_humdifier()
    humid_on = True
else:
    turn_off_humdifier()
    humid_on = False
	
// Dehumidifier setting

if (humid >= min_humid) and not humid_on:
    turn_on_dehumdifier()
    dehmd_on = True
else:
    turn_off_dehumdifier()
        dehmd_on = False

I can see how to do some of this in the Smartthings app but not sure how to set/unset the status flags via the app so would appreciate any suggestions. Thanks in advance!

Do you even need those status flags? You can just use the on/off state of each smart plug as preconditions given that’s how you control the humidifier and dehumidifier.

Ah, hadn’t thought of that … but is pretty obvious now you mention it :wink:
