Budget solution for server room thermal monitoring

[maxermaxer]

Can anyone please suggest a budget solution for monitoring the temperature of server room ambient temperature? I would like the monitor to be able to send alert through email/apps to me when I am away from the server room. If there is also LiveCam monitoring it would be even better. Thanks!

This is on my radar: Cheap environmental monitoring with Raspberry Pi/Grafana/InfluxDB – ops and automation

In the past I've done this using inexpensive consumer temperature/RH sensors usually used with weather stations (or other 433 MHz sensor) combined with an RTL2832 based USB SDR stick.

GitHub - merbanan/rtl_433: Application using librtlsdr to decode the temperature from a wireless temperature sensor (433.92MHz)

Depends on the budget, but a lot of environmental monitoring devices turn up cheaply on ebay, like NEW Unite Sinetica Hawk-i3 Web Managed Environmental Monitoring Device ZAHI3-01 | eBay (will need sensor's).
If you have an APC UPS you can add some sensors to that too

Not exactly serverroom temperature but you can use smartmontools to readout disk temperature, and use it as an alert indicator

Older generation APC NetBotz are very cheap on eBay.

Wanna combine two birds with one stone?

COTS web cam software and conventional thermometer. Get one for the visually impaired and it will have a big display.

Won't handle notifications but will handle looksie and temperature observation.
