Probably tinkering too much 🙂 Of course, as your improvement is so dramatic, do you think it could be due to less memory swapping? I am not sure how large the swap block is on the HP2023. Similarly, on my non expandable HP2019 I have less than 5% free after offloading several apps. 😑 So I will have to find the solution elsewhere and the swap block is just 9.7MB. CPU 1. I tried the tools page but see no app \> 1% CPU. 2. I also tried with Insights, but the CPU per app just increases overtime, I cannot conclude anything from this. 3. I asked Athom how I could make my Homey more efficient: there is no better metric, I was advised to look in the flows for many commands or flows with lots of variables, many devices and logic and they say as a rule it helps to add delays between devices and commands. We knew that already. 😉 and “The rest is trial and error I’m afraid, but with the huge number of devices and virtual devices running a busy Homey is unavoidable, so it’s a matter of finetuning”. After reading this, I did find that I had many flows/checks being run in parallel every time a motion sensor (I have 20x and 200 advanced flows) sees activity or after its nonactive period. By adding some delays and using [Advanced triggers](https://community.homey.app/t/app-pro-advanced-triggers-trigger-and-action-cards-with-eventname-for-advanced-flows/65651) with debouncing on the trigger (amazing app!) , I could bring down CPU to about 35-95%. Still too high, but I am still working through the flows 🥲 PS I am not sure this thread is right for my comments, but they relate to finding out the efficient use of the system. If you know a better one, let me know. --- _[View the full topic](https://community.homey.app/t/app-pro-sysinternals-shows-homey-s-system-internals/78650)._
