Temp-443Mhz

Temperature and humidity to PRTG by 443 MHz

A private project to get temperature and humidity readings to PRTG.

Needed;

• Telldus (Duo)
• Temperature sensors, I used cheep Telldus termo and humidity sensors, 3 pack at ~400 SEK

Dependencys

1. Install TelldusCenter
2. Find out channel ID of the sensors.

   & 'C:\Program Files (x86)\Telldus\tdtool.exe' --list-sensors

Screenshots

Instructions

Install and start Tellduscenter to find out the channel ID of the sensor you want to read and import to PRTG. A Powershell script start the x86 program to export all the sensors to a a string for each sensor. The script filters the output and returns the reading in a PRTG XML syntax.

Write-Output "<prtg>"
    Write-Output "<result>"
        Write-Output "<channel>Temperature</channel>"
        Write-Output "<showChart>1</showChart>"
        Write-Output "<showTable>1</showTable>"
        Write-Output "<value>$temperature</value>"
    Write-Output "</result>"
    Write-Output "<result>"
        Write-Output "<channel>Humidity</channel>"
        Write-Output "<showChart>1</showChart>"
        Write-Output "<showTable>1</showTable>"
        Write-Output "<value>$humidity</value>"
    Write-Output "</result>"
Write-Output "</prtg>"

You can chose to run the script directly from the PRTG probe server or as I do in this home environment a call the script localy on the machine that has the physical Telldus duo installed by powershell invoke-command

Error handling

NO 🙈
