First, I want to compare two sensor values (abs. humidity, calculated it in a template sensor). One inside and one outside. If the abs. humidity inside is much bigger than the abs. humidity inside, I want to start a fan (via PWM) for a certain time.
As I am new to HA, I would like to ask you which is the smartest way to realize this operation.
Second, I want the fan also to start if somebody opens the garage door (recognized via reed sensor) and closes it afterwards (to drive a car into the garage or something like that). The problem here is that I donât want the fan to start every time when someone, for example, opens the garage door 4 times in 10 minutes. So how can I add a specific time in which the automation wonât start again?
Third: Is it possible to put the PWM for example to 30% between 10 pm and 7 am and for the rest of the day to 80% power?
A lot of questions, I know. Hope you understand my English.
All of those things are possible. Have you connected the fan to Home Assistant? The way Home Assistant communicates with the fan controller will determine how you need to design the actions of your automation.
Is there a possibility to declare in the action âturn the fan on for 10 minutes and then turn it offâ? (Turning on and off is clear to me, just the question if there is a function to declare the 10 minutes duration)
In conclusion, everything works as expected. Thank you guys!
Only my aht10 sensor gives some temperature values outside arenât that accurate. Just have to figure out whether itâs the positioning or the sensor itself.
