Still loving my Homey but to learn a bit more i would like to ask what the correct method is to integrate certain flow steps in Flows that have certain values. My situation is that i want to control the mechanical ventilation. I`ll explain:
I have started several years ago with X10. When i bought my house there was only a mechanical 3 way turn switch in the kitchen that lets me select the setting for the ventilation. The motor was an older model J.E. Stork Air CML model. Every morning before showering i had to go to the kitchen to adjust the ventilation. You get that that was not sustainable for very long. So i decided to automate this. I have connected 2x Eaton SAIX-12 X10 modules to the motors which controls the power lines for selecting the right speed. In the bathroom there is a SS13E X10 wall button switch. Many people have these kind of motors in their homes. And i have seen more threads about this. Now its not especially that i want to know how i get this motor running through Homey (then i could read the other threads again) but more about the correct way to design flow actions above or under certain percentage thresholds.
So how it works now: When both SAIX12-#1 + SAIX12-#2 are off the motor runs just 1 line. Normal 230 volts. When SAIX12-#1 is on and #2 is off then the motor runs at the middel setting. When #1 + #2 are on the motor runs on full speed.
I have placed a Xiaomi Aqara Humidity sensor in the bathroom which works unbelievably well for its price. Its very small, feels high quality (for Chinese standards) and detects changes very quickly. In 1 minute after turning on the shower the commands are sent to the SAIX12 modules and the fan starts pulling the humidity out of the bathroom. I have set that when the humidity changes and it gets ABOVE 80% it triggers a flow that sends a command to SAIX12-#1 = #2 to ON + send a Push Message to my iPhone (temporarily, for testing purposes). When the humidity is going down and under 80% again it turns the SAIX12 modules OFF again with a delay of 15 minutes (because 80% is relatively high).
The problem i have here is that with every humidity change (which can be 0,1%) it triggers the flow everytime which causes the X10 signals to be sent over and over to the SAIX12 modules and it creates a Push Notification. These signals are unnecessary and i would like to create my flow that the signals are only sent ONCE after the humidity level reaches ABOVE 80%. Not that i am an “Aluhoedje” thats needs to lower the amount of signals but its just that i want to learn how to do this and to have the system use its resources properly.
I could not find the correct way to do this with the built in Homey logic. Preferably i would like to do it with the built in logic ways instead of installing other apps for this (i have seen Countdown, Better Logic used etc).
I have added a screenshot of the flow.
Thanks in advance for reading and looking forward on everyones thoughts in how to do this correctly. Then maybe we could create a single file or thread on this for new people starting with Homey.
