forgot administrator password

If you type http://your_ecu_ip/recovery/recover.php you will enter a secret page where you can drop your wifi credentials. At reboot the accesspoint RadioAP is started. Now you can enter a new password.

pairing fails

The zigbee seem to work but pairing does not succeed.

• change the ecu-id to D8A3011B9780 , this ID has proven to work.

system seems slow.

If you upgraded to version 3_2 or above, you may experience lower reaction speed in the webinterface. The reason is that there is more data displayed on some pages. These pages need much more calculation before ready. You can improve this by installing 'zram-swap'. This patch uses the memory insteat of the sdcard for swapping, which makes it a lot faster.
In addition, the SD card wears less.
If you installed v3_3 via the sd image, zram is already installed so you don't need to do this.
You can download this software patch here: ecu_swupgrade_zram.tar
and install it via menu->system->update just like a normal software upgrade.

OR burn sd-card image v3_3 or above (don't forget to backup your databases/settings)

OR do the following:

ssh into your ecu, login als root. you are in the directory /root. Now:

git clone https://github.com/foundObjects/zram-swap.git
cd zram-swap && sudo ./install.sh

edit /etc/sysctl.conf:

nano /etc/sysctl.conf

add at the end of the file:
****************** hansiart mods **********
vm.vfs_cache_pressure=500
vm.swappiness=100
vm.dirty_background_ratio=1
vm.dirty_ratio=50

than reboot or sysctl --system
test with cat /proc/swaps
