Hi

Below is the recommended Operating Temperature as well as Storage Temperature ranges

• Operating: 32° to 104° F (0 to 40° C)
• Storage: -4° to 122° F (-20° to 50° C)

I’d wouldn’t push toward either end of the above for an extended period of time. So use your best judgement. 😊

The other consideration is WiFi signal reach unless you intend to wire it to your router. However, if using it to power surrounds for a Sonos soundbar you must consider penetration for 5Ghz passing through whatever is between it and the soundbar.
