85°C isn't an error value but the power-on value.
If you get bogus 85°C readings, check the power to the sensors, and also
the bus for shorts.

Don't mix [/uncached]/<id>/temperature[X] and
/simultaneous/temperature. Use the latter only in combination with
[/uncached]/<id>/latesttemp

Mixing both the single-target and the simultaneous method on the same
bus has no benefit but a negative impact.
The only reason to use the single-target method is when your sensors
aren't powered.
