Home Assistant eMMC lifetime

trurl101 · April 25, 2026, 1:58pm

I bought the Home Assistant Green about a year ago, and the eMMC lifetime is already at “80% used.”

This isn’t mentioned in the FAQ, in fact, the device is promoted as “beginner-friendly.” A system with a maximum lifespan of around two years is anything but beginner-friendly.

I’ve since learned that it’s recommended to use a USB SSD from the start to reduce wear on the internal storage. I could still do that now, but it’s concerning that the eMMC is already close to wearing out and could fail within a few months.

Does this mean I now have to buy a completely new system for Home Assistant and discard the Green?

The HA Green is advertised as user-friendly, but this situation is unacceptable.

Just plug in a USB SSD and use the move data function to migrate. It just have to be larger than the current size.

The eMMC lifetime will not deteriorate while you are on the USB SSD.

Third Reality 3RSPE01044BZ doesn't always respect reporting settings

problem

### What happened? I have 20 3RSPE01044BZ smart plugs. They're great, but very …chatty, and with so many of them, my zigbee network can sometimes get overloaded (buttons start to take several seconds to respond for instance). So I change the reporting settings so they report less often and this mostly solves the problem. However, when a plug is turned off, it doesn't respect the custom reporting settings anymore and starts updating as fast as it can again. ### How to reproduce it (minimal and precise) I changed the reporting settings as follows: rmsCurrent: 3600 7200 5 rmsVoltage: 3600 7200 50 activePower: 30 3600 10 Voltage and current is less important to me, so it very rarely updates those. Power is updated at least every 30 seconds. <img width="397" height="215" alt="Image" src="https://github.com/user-attachments/assets/56e6b9d8-27df-401e-ba79-06ee5a3fad31" /> On this graph you can see, during the first 30 minutes the plug was turned on (but with nothing plugged in, so the power draw is minimal). The graph updates every 30 seconds, as intended. During the last 30 minutes I turned off the plug, and clearly the graph is updated much more frequently again, ignoring the custom reporting settings. When most of my plugs are turned off, the network gets overwhelmed again. ### Zigbee2MQTT version 2.9.1 ### Adapter firmware version Revision: 8.0.2 [GA] ### Adapter SLZB-06M ### Setup I run Z2M as an add-on on HAOS. I'm running the latest firmware on the plugs: [1.01.01] 20251126 1702-3R App: 1.0 build 1 Stack: 3.0 build 101

The third reality smart plugs flooded the zigbee network, the log files and the database.

Home Assistant Green should provide some form of warning when something like this risk compromising the whole system. I mean if the eMMC lifetime decreases rapidly over a few weeks it should be easy for the system to provide some warning that something unusual is happening.

A user that bought the HA green the easiest way you can start using Home Assistant. It's plug-and-play..., can unknowingly break their system just by adding some smart plugs, without any kind of warning system in place?

Integrating the SSD worked without any problems. I plugged it into the USB port of the HAGreen and clicked on “System/Storage/Move Data Disk”.

No formatting of the SSD was required, and after about 15 minutes, Home Assistant booted normally.

My only concern is that the eMMC (already at 80% lifetime usage) might still be used for certain tasks, such as system updates.

A system like this really shouldn’t rely on eMMC at all.
