Thermometer auto kill switch ?

[TrabajoDeLaNoche]

Hello,

I want to set up an auto switch if the temperature is too high for safety.
The idea is to switch off the miners if the temperature is over xx.
How can I do this ? Also what would be the best setting to kill off the miners ? I have 35 L3+ miners on the way.

Best regards,

There are digital thermometer "AC line switches" that will handle 15 amps - you could set one of these up on the input of your power supply.

 I don't recommend it though - IMO you'd be better off just reducing the clock on your miner to keep it cool as needed.

 Also, doesn't the L3+ have auto-adjust software like the S9 or the Spondoolies SP20 that auto-tunes it for you based on temp and stuff?

I'm not sure as I haven't received the miners yet, thanks for your answer.

You can make it with Arduino.

A managed PDU (fancy power strip) can have temperature and humidity sensors as well as providing access to switching off individual plugs to cycle the miner.

You can write a small script to read these values out of SNMP and take the appropriate action if you choose, or you may find the software that the PDU comes with has a similar function.

Nodemcu/arduino + waterproof temp. sensor + relay module will do this.
The software side is doable with the references provided here
