Fibaro Intercom gets *** VERY HOT ***

[Fitchie71 0]

All,

 

 

I  bought my Fibaro Intercom a long time ago, have experimented with it in the past, but only recently definitively installed it.

It seems that the heat sink inside the wall box reaches far too high temperatures.

 

Tested on the kitchen table with the termocouple near (but not against) the heat sink, each test lasted for >3 hours:

 

- Ethernet with PoE : 55 ° Celcius

- Ethernet with 12 VDC external power : 50 ° Celcius

- Ethernet with 9 VDC external power : 49 ° Celcius

 

Now it has been installed in the wall box, and I'm worrying what will happen when the sun will shine on it within a few months ?

I have also read the other topics, where it is indicated that this behaviour is normal, but I cannot imagine that such high temperatures are "healthy" for the inside electronics.

 

1. What is the experience of others who have been using the intercom for longer time ?

2. How can I measure/monitor the inside temperature of the device ?

 

Thanks before hand for your reply.

TBH those temperatures are normal for FIBARO intercom

Regarding temperature, no worries:

 

Regarding Q1 - we have here, since Intercom has been released to public, one installed in direct sunshine all the day. It crashed only twice 2 yrs ago, last year it just turned off video (till temp. dropped). However, that might be different for other locations/walls (one of our Intercom customers repaired once, replaced twice, and finally removed Intercom, as it was crashing 1-2 times per day durring hot summer. But that was energy saving house, with very good temp insluation, and actully no way to get rid of the heat withing the insulated wall).
 

Regarding Q2 - yes, there is API call but not available for users. It would anyway tell only the CPU temperature, which does not matter, as the CPU can get up to 125°. From my experience the API reported temp was always 10° higher than the temperature measured on the body/heatsink, which is perfectly ok.

Totally agree with that.

Under normal conditions of use mine turns between 48 and 70 ° C

All,

 

Thanks for the feedback. I understand that I don't have to worry about the high temperature, although it feels a bit uncomfortable.

 

To my knowledge electronics degrade quadratically with every doubling of the temperature.

Krikroff,

 

Thanks for your nice tool, I checked the temperature with your tool, 59 °C in normal conditions.

It seems I have an even older serial number than you.
