Homey Pro - Advertised Storage size

[Glenn_Dijkstra]

Hi there, I was wondering. Homey pro should have 8 gb internal storage, when I look into homey pro, it says like 2,7 gb memory and your app even says less.
How can I interprete those values?

The new Homey Pro — Ask Me Anything

So the homey has multiple Partitions 2x Boot ~300mb 2x System ~2,3GB 1x User ~2,7GB In total ~8 GB Why this system? Currently, a Homey update is an image of the boot and system drives. Because you can’t write to the currently active partition, there are two boot and system drives, so the currently inactive partition can be updated. They switch the partitions from A to B after the upgrade, and then back to A after the next update. I don’t know if they will change the system to a different u…

moved to a dedicated topic as it has nothing to do with sysInternals

This isn’t much difference with the previous model that also was sold with the installed capacity. And a lower unable capacity

as it has nothing to do with sysInternals

A bit though, while one of the Q’s was:
How come Athom/Homey sysinfo show “2700MB” total diskspace, but SysInternals shows “2535MB”

Can it be because of different calculation methods?
What is the “real” number?

Ah, sorry You are right, I reacted on the 8 GB vs 2,x GB usable…

@Peter_Kawa

show “2700MB” total diskspace

No, it doesn’t say 2700 MB, it says 2,7 GB
Actually it is:

Homey.system.getStorageInfo();
Response
"root":{4 items
"total":float 2657828864

Athom makes=> 2657828864 bytes / 1000³ => 2,657 GB rounded to => 2,7 GB (Pronounce GigaByte)

And Sorry, maybe I am old and from before 1998 ¹ in computers,
I still use/write MB where I calculate it the way I learned in school:
2657828864 / 1024² = 2534.7 => Rounded to 2535 MiB to be correct Pronounce mebiByte

But to make it even more complex, where I apply the (older) JEDEC standard for calculation that is more and more replaced by the storage vendors by the IEC standard, this older JEDEC standard (based on powers of 2) is still used for Memory… a MB is there 1048576 (i.e., 2²⁰)
