+### UPS Plus
+
+An **uninterruptible power supply** (UPS) is very useful if you have your own servers at
+home. I've been using one with my old DiskStation (NAS[^1]) but I got rid of the DiskStation
+at the end of 2023. I got the UPS Plus for the Raspberry Pi now for a while but never tested
+all its features yet (well, I haven't used it much to be honest).
+
+Though, I have some quick notes to remember:
+
+Some software is needed to get status information about the batteries (which are of type 18650).
+
+~~~console
+$ python3 -m venv .
+$ curl -LsO https://raw.githubusercontent.com/geeekpi/upsplus/main/install.sh
+$ bash install.sh
+~~~
+
+Any errors can be resolved by installing by hand. In my notes I thought that info is enough, so
+here we are :wink:
+
+We may have to edit our crontab:
+
+~~~cron
+* * * * * /home/dr/bin/python3 /home/dr/bin/upsPlus.py > /tmp/upsPlus.log
+* * * * * /home/dr/bin/python3 /home/dr/bin/upsPlus_iot.py > /tmp/upsPlus_iot.log

 ## Raspberry Pi 2
 
+### WiFi adapter
+
+The Raspberry Pi 2 does not have any WiFi capabilities so an adapter
+is needed to make use of your local WiFi network. I found [this small
+adapter](https://www.amazon.de/gp/product/B003MTTJOY/) and can confirm
+it as a working unit.
+

+on Amazon any more, but they suggest another device as its successor. I can only speak for the
+one that I own: **Edimax EW-7811Un**")

 The mic is usually located very easily, though the elements below the hole are very, very small.
 I used a sharp cutting knife and a sharp side cutter to remove the tiny circuit board.
