Hi Fellow Homey User, I need help with a flow to notify me only once in 30 minutes. See my flow below. What happened is im getting notification almost every minute when drizzling. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/1X/bbbad25e7a7713f9e662e047bab7bf6b6f043bcc.jpeg) Please advise. Thank you ---

Which water sensor are u using as a rain detector? I’m curios as I’ve not had luck with one that works well without draining the battery fast… Create a better logic variable, name it notification or something. Either a boolean or number, then set the variable to true or as the example below, i increment it 1 time. And the flow will stop once it notify me twice that the ziptrak is closed. You then need to create another flow to reset the better logic variable when u open the ziptrak for e.g… Or in your case, every 30mins, set variable to 0 or false… ![39%20AM](https://us1.discourse-cdn.com/flex025/uploads/athom/original/1X/7bbfdba4392094def06a3fd26874a95c7bcd8241.png) ---

Im using Aeotec water sensor but app from automate Asia. Works fine with me. Found a countdown timer app and this resolved my problem. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/1X/39edc13e65ae9d1d71419da86d3f69eb4452619f.jpeg) Thank you ---

I also use a counter for counting 15minutes for raindetection by “buienalarm” Setting the counter when rain is detected ![Knipsel](https://us1.discourse-cdn.com/flex025/uploads/athom/original/1X/4f22434bda2eb66ccc948988a6d8414e0e57db57.png) ---

Or if u use the candy app, u can use the card “this flow is ran in the last 30mins”… much cleaner than the timer Unless u need to trigger an action on timeout… ---

you can also set a card turn off flow followd by a turn on flow card with a timer on it. I this case the flow turns itself off after doing the jobs and goes back on after 30min waiting. No need for extra apps this way.
