Sorry, but how is everybody reporting homepod temperatures, is there a function to check inside temp ?
I have 9 homepods, on 15.1 all of them. and no temp issues now that I fixed the few that grilled.
What I think in my personal opinion, one of the reasons that makes the temperature high when I tested the Hompods dismantled, is when your iphone is near and it downloads new firmware for homepod in Home app, even when in settings, software update is OFF.
The iphone downloads the firmare, and transmit it automatically to the homepod. EVEN when you chose not to update the firmware. Then you see in Homeapp, 'update available'
The moment if iphone is transmitting the firmware, the iphone goes out of reach of the Homepod, the homepod struggles turning on bluetooth and WiFi searching for the iphone connection.
The culprit is a diode on the control board of the Homepod, found out searching on the web.
When all is struggling, Siri listening, music playing, bluetooth and wifi searching, this diode heats up.
The diode sits on the board and the board has a protective black Dye .
When Diode heats up, it is melting the Dye and shorting with the board negative copper circuit.
Two alternatives on this.
Either it shorts a tad and kills the motherboard firmware. in this scenario the Homepod lights up again when cold, with plus and minus buttons flashing. This would render Homepod impossible to repair, since firmware impossible to clone on the board
Or it shorts and bonds with the pcb circuit, where the Homepod would not start again. fixable by resoldering new diode
If you are tempted to replug your Homepod , and want to be on the safe side, when you plug it, keep your iphone next to it with bluetooth and wifi on, if in Home settings you see in software update the firmware downloading.
Just don't play music for the couple of minutes that the firmware downloads. my 2cts
