Just check to see of anyone else got 2 peaks within the hour after lunch today? ![1000035690](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/0/308ce81d2eff6efcd71b215ef50b26bc9c63d138.jpeg) ---

nope, just every two hours. My Homey is veeeeery slow (especially Zwave) in these periods. Or its even missing signals. ---

Like this? (My local time is UTC+2) ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/5/95cedb838ce3e1c2486a81721acc1bbf3778c6e9.png) ---

Yes, about the same but 4 days ago… Today I got peaks about 3h apart mid-day. No really pattern here it seems. 🤔 ---

Same here every 2 hours it peaks to 70% ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/1/5135cc95d1c11939609f82dfda65c0ddf9747d9a.png) ---

Same problem here. And in this time period, especially z-wave is very slow, and often does not respond at all. I’ve been a Homey user for 10 days now, and I am not impressed ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/f/9f700c46588097e461f01a779480ff74a4ba8fc7.png) ---

I have my Homey Pro running with only 2 apps and no flows (waiting out the Zwave bug before migrating…), so it is doing absolutely nothing. But I see these 2-hourly CPU load spikes as well. ---

If this is the case, can you contact Athom please ? Because if unloaded Homey is doing it, it’s something under-laying in the homey-pro core itself and would be very nice to provide them diag/info without noise (eg. like many of us having \>10 apps \>100 devices \>xxx flows etc. ---

Just to be sure it is not within the apps I deleted everything, will see if it still peaks now and then report to Athom. Although I can hardly imagine that they don’t see this behaviour themselves on any of their presumably a couple of dozen test devices. ---

> [@Jo\_San](#): > > it is not within the apps I deleted everything I have analyzed CPU utilisation of all my ~50 apps already before and I know it’s not caused by any of them … it’s the homey-pro core process (Node.JS based), which is causing it. > [@Jo\_San](#): > > hardly imagine that they don’t see this behaviour themselves Yeah, they may even not have focus on such problem right know…don’t forget, then need to fix ZWAVE, Bluetooth…implement Thread, extend Satellite Bridge… and many many more. This is just to ensure they have more calls and more reports, so that they will be looking on it - it’s about prioritisation. ---

I also experience the build up in Memory usage by Homey: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/9/f909e8195ae5180091a1f10d4221b3c85083108c.png) After a restart this returns back to “normal”: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/7/a/7a7d096273eedef3652458a1b7ae9d270e613049.png) Do more of you have this issue? ---

I haven’t any memory buildup issues, can run almost 2 weeks at around 500MB free. Clarification: around 10MB build up per day. ---

Yes, free mem goes down over time as well… but didn’t check if it’s due to the core process ---
