HAM GPISense

The serial number starts with e14:. The older version has a serial number that starts with 35:.
What it measures
Section titled “What it measures”| Reading | Unit | Note |
|---|---|---|
| General input 1-4 | open / closed | One reading for each contact you connect. |
| Input counter 1-4 | count | Counts the changes of the input. Use it for pulse meters. |
The app shows each input as Gen. In., Gen. In. 2 and so on until you give it a name, for example “Storage door”. You can also give your own names to the open and closed states. An input shows when you give it a name or when its counter counts something. The counter shows with the input name and the word Counter.
