It depends on different things if it will, or if it will not work in parallel. So my recommendation is to try it out by yourself. **Edit** Some more information: > [@Slow Flow](https://community.homey.app/t/slow-flow/79623/12): > > I received some tips from Athom yesterday on how flows work. Maybe it will help you. Since you are using advanced flows, bear this in mind. In normal flows the entire “Then” block of flow cards is fired as fast as possible. So if you need to have a certain order to your commands you have to use delay blocks in normal flows to guarantee the right order. In advanced flows flow cards are always fired sequentially if the flow is constructed that way (which is different from normal flows).
