Multi Chemistry Watch dog is just amazing!

This multi chemistry super watch dog is amazing! I have been a big fan of LiFePo4 batteries for a while for their safety but this will also run on Sodium-ion cells. I am very impressed! This hat can power a Raspberry pi 5 and a 10” screen at 65% brightness. The sample scripts are super useful with data logging already setup to simplify integration. An absolute necessity for Codesys applications using persistent memory but also super useful for 1 button appliance style shut down.

Great product!

This is a great article. I will use it for my industrial control classes. Please change the order of the wires in the 24 V connector or use the same order for all hats (industrial automation hat v4 in my case), so we can change the plug from one hat to another without problem (I burned my 24 V connection because of that). And a 24 V reverse voltage protection could be a plus for a new version.

Perfect battery backup with room for two 18650 - runs for hours

Watchdog works as expected. Two 18650 of 5Ah each can power my Raspberry Pi for many hours. Very useful HAT

Documentation missing

While I like the Watchdog, it mostly does what it is supposed to do, the documentation is only for version 6.0, while I have Version 7.0

Also, not all details about the behaviour are well explained, e.g. how to do a clean shutdown of the raspberry disabling the watchdog, and how to turn it back on afterwards through an external button.

Great product

The Super Watchdog is a great product. I use the previous version productively in my private home automation environment. In the event of a power outage, it keeps my Raspberry Pi4 running for 2.5 hours before shutting it down. After the voltage returns, it restarts it.
Very reliable and professional.
