reading board/cpu temperature

RouterOS Wireless Networking
1

Hi,

We made a mini-itx intel-based and passive cooled system. When you use routerboards you can read out the cpu/board temperature in winbox.

Does anyone know if there is any possibility to read out the cpu temp with other hardware in winbox? Or is there some hardware usb- or serial sensor that I can plug into the usb port of this board that works with routeros/winbox with or without a script/plugin?


regards,
arco

Hi Arco,

Sadly, answers are no, and no.

It’s been asked for before. Apparently, in general linux OS builds it has been done before, i.e. apps that read out the temp sensors even for diverse types of motherboards.
Either it’s not top of MT’s priority list, or they don’t want to do it, or it’s much harder to integrate than it might seem at a glance.

Even if you bought/built a temp sense<>RS232 or USB converter, how do you get the read-out into winbox? MT would still have to integrate that I think.

ok, bad luck. but…

if enough users overhere wants to implement this in winbox, why not choose 1 usb-sensor all, and then send 1 item to mikrotik and ask to implement this?

any one else interested? Let’s make a list and then search for a nice product.

Well, that’s a great idea.
Any commercial low-cost ones out there? Suggestions?
Otherwise, hack one together …

It would make sense for all PC-based MT boxes, i.e. even if you use a “beige box” PC as a router, if a fan fails, you would like to know …

ok, let’s invite everyone…

maybe we should search for a component with 3 sensors. 1 for connecting to the cooling block of the cpu, 1 for the temperature in the box and 1 box the humidity.

hope some others should read this… and mikrotik..

Hi
Very much interested in this idea of reading system temp!!!

Digitemp is a Temperature Sensors for Linux
for the Serial Port..

DigiTemp now supports the following 1-wire temperature sensors: DS18S20 (and DS1820), DS18B20, DS1822, the DS2438 Smart Battery Monitor, DS2422 and DS2423 Counters, DS2409 MicroLAN Coupler (used in 1-wire hubs), and the AAG TAI-8540 humidity sensor.

The last version of digitemp adds DS1923 Hygrochron support…

Pleasssse… Mikrotik Guys make a “Digitemp” RouterOS package

Nice post, interesting gear. Certainly would be a solution, better than where we are now.

IMHO:
1st preference: “use the onboard sensors”: they’re already on the motherboard, and linux software exists.
2nd preference: “add on dongle” like those. Plenty of 1-wire devices around.

What’s going to cause problems is “no solution”. People are going to keep building x86 routers even when the faster MT boards come out. Fast routers = lots of traffic = CPUs generating heat = mission critical. All go together
We don’t NEED temp sensors in every CPE - but would DO on base stations and backbone routers.
And indoor routers it’d be a really good idea too, especially as fan failures can be tracked as well as CPU PSU and chipset temps if the I2C sensors can be read.

Would like to hear more on this topic -
