> [@Frequently Asked Questions](https://community.openenergymonitor.org/t/frequently-asked-questions/3005/2):
>
> Q: How do I update my emonPi / emonBase without reflashing the SD card?
> 
> A:
> 
> You can use the “emonPi Update” or “emonBase Update” buttons, which you find under Setup -\> Administration (scroll down to “Update”).
> 
> If you have an emonPi with a totally stock sketch, you are best using “emonPi Update” to keep up to date.  
> If you have an emonPi with a modified sketch, you are best using “emonBase Update” to avoid overwriting.  
> If you have an emonBase with a RFM69 based RFM2Pi or RFM69Pi running a totally stock sketch, you are best using “emonBase Update” to keep it updated.  
> If you have an emonBase with a RFM69 based RFM2Pi or RFM69Pi running a modified sketch
> 
> OR if you have a RFM12 based RFM2Pi
> 
> OR you are unsure what RFM2Pi you have,
> 
> you should use “emonPi Update” to avoid over-writing the firmware.
> 
> Aside from the firmware differences, both buttons fully update the emonSD used in both the emonPi and emonBase. There is no separate emonHub update button, emonHub is updated along with emonCMS and other software in that same emonSD update.

I would probably include a link back here for those that want to know more otherwise the next FAQ is going to “Why”

(Looks like Bill gets credit for your edit as he is the OP of the FAQ topic)
