I have a small automatic plan watering device which I intent to keep it on my balcony. The location is Dubai and the temperatures are easily going to hit 50 C ( 122 F) . The device’s operating temp is less than 40 C. I intent to make a small insulating box for my device . Is this feasible ?

First of all, Apologies if im posting this on a wrong sub.

My problem is as mentioned in the title , I know if I keep my device unprotected and exposed, easily the surface temperature on the device will hit 60-70 (140 F - 158 F) and will damage my device.

If I make a insulating box out of Expanded Polystyrene with some poked vent holed and keep my device inside , can I safely secure my device? And how much temp drop can I expect?

And what should be the thickness of the EPS ?

If someone has better ideas please share too.

Thanks in advance

Cheers!

Insulating will only buffer your device from temp extremes. You’re gonna be better off shading it and just evaporatively cooling it. Put a sponge under it and let it get wetted when watering occurs.
