Data from a DHT22 sensor connected to Milkv-Duo in den updated every 10 minutes by ssh transfer of values from the Milkv-Duo to the server:
| date/time | temperature deg F | humidity % |
|---|---|---|
| -- | -- | -- |
Line voltage provided by attached UPS, with nut (network ups tools) providing monitoring and access to data, that is logged by a systemd-timer every 10 minutes. The log file is parsed by awk to obtain the current line voltage, the average, minimum and maximum values and the date when each value was first seen.
The information is included here by an Ajax call to a php script on the server which invokes the awk-script and transmits the response to this page.
