Im interested in buying the homey-pro but due to so any devices I already have the homeassistent on my end (vm on proxmox cluster) uses almost 3.5 GB sometimes almost 4GB of RAM. Due to the Homey Pro just having 2GB is there a way to upgrade the CM module inside to the 4GB model or other way like zram to “improve” the ram situation? KInd regards, ---

Yea but this is not really supported. Is there a supported way from Homey itself to fix that issue? ---

But is is hard to compare memory usage on totally different platforms like HA and Homey. How many apps/brands are you planning to use? I know, tough to look ahead, but it might give more of an idea than the current HA memory usage. ---

Also, is that 3.5/4GB of memory for the entire VM, or for HA alone? Because the latter seems excessive, my HA installation requires about 1GB for about 300 devices (3000 entities). ---

Its the whole VM, I am suing HomeAssistent OS (HAOS), so IDK but yea could be a “layer-8 Problem” in my case. IF Homey is working for you fine with your integrations I should be fine too. Im just scared that there is no head room / room for improvment there. ---

Okay has someone a deployment like you have? with 3000 entities and 300 devices? I have 100 devices and arount 1200 enteties. I need someone who can tell me that the homey can manage that with apps and all. ---

I think any Homey Pro won’t have any problem with those numbers My setup I have these HA devices ‘installed’ @ Homey Pro 2019 (1GB RAM): > ![1000041404](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/d/2d3e2d0a172f615d19075ad3e948bd36e3ab2925.jpeg) MQTT (incl Z2M) has this number of entities: > ![1000041398](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/c/1c378b759639f9bc5515ae44c86360beefc8f9b7.jpeg) HA CPU & RAM (of course it runs way more than only MQTT): > ![1000041400](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/0/e0a050cea6ba34d532b7142bf7366a05c6580ead.jpeg) Homey: The needed apps use this amounts of RAM : > ![1000041403](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/0/e02865b147f4420064f5223ad58cf8753652fc81.jpeg) (In general they use double on a Pro 23)
