uncached/temperature will always trigger a conversion and then read the
uncached/latesttemp will never trigger a conversion but read the last
value from the device.

What the cached versions will do is anybody's guess, mainly depending on
how long ago you last read them.

Since all of my 18b20 devices are powered, I simply write 1 to
simultaneous/temperature, wait a second, then read every chip's
uncached/latesttemp, write these values to whatever wants them (MQTT,
AMQP, etcd, …), wait 30 seconds, repeat.

I don't use the cached versions at all.
