Hi all, I need some help with creating a flow. I want to test if the air quality in the different rooms where I have a Netatmo weather station is below 1000 ppm. If that’s not the case, then I would have my Google Mini speak a message, saying that I need to ventilate that specific room. So far, I don’t have any problems: when ppm \> 1000 ==\> Google mini: say text However, after, say, one hour, I want to re-test and see if the values have decreased. If yes, stop the flow (or let the mini Google say I can close the window, if it is cold outside). If no, then the spoken text should be that I need to do more, maybe with the use of a fan… So, can anyone help me with this? This problem is, if I leave out the Netatmo and Google Mini: Test if something is true - If Yes: All OK, stop the flow - If No: 1. Do something 2. Wait 3600 seconds or 1 hour 3. Do the same test again - If still Yes: Do something else - If No: All OK, stop the flow Hope this is clear… 😅 Thx, Joh@n ---

For the wait/timer part, consider using the [Chronograph](https://homey.app/en-nl/app/nl.fellownet.chronograph/Chronograph/) app. You would then add the following THEN card to the end of your existing flow (with the ventilate message): ![IMG_2143](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/9/d98fae22a140bcfe67881e8076ae1c4eff55208e.jpeg) Next, your second flow would start with the following WHEN card: ![IMG_2145](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/4/5472db99f8b4becc5dc1c6068e447448a9e1df19.jpeg) So the second flow is triggered after the 1 hour delay. Then you perform the checks you want. If the ppm is still above 1000, you could restart the timer using the first card I mentioned above. So it would keep on reminding you every hour if the ppm is not below 1000. ---

Just another way to formulate your flow ```auto WHEN every 1 hour ``` ```auto AND condition is TRUE ``` ```auto THEN do something ``` ```auto ELSE do something else ``` PS: in stead of formulating “stop flow” I would suggest “the flow ends”, as you cannot stop a flow that is runnning ---

> [@SunBeech](#): > > For the wait/timer part, consider using the [Chronograph](https://homey.app/en-nl/app/nl.fellownet.chronograph/Chronograph/) app. Unfortunately, I still have issues with this flow. The Netatmo app doesn’t have any AND-cards, and even if I use a WHEN-card and combine it in an ALL, it still won’t work, because the WHEN-card for Netatmo checks if the value “Becomes greater than” 1000 in my example, but in fact the value was already over 1000, so it doesn’t “become” greater…. What I need is a WHEN-card that asks “IS” my value \> than 1000 and not “BECOMES” \> than 1000. ---

You can achieve this by using Netatmo’s WHEN card ‘The CO2 level changed’, followed by a Logic card in which you check whether the changed level is greater than 1000 ppm: ![IMG_2147](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/5/c5df4d6404a6b9236569a0df52dbf7176a927aff.jpeg) ---

A combination of your double feedback did the trick. Thanks, man, for your extensive knowledge. Joh@n
