Sure. E.g.
http://www.beckhoff.de/english.asp?ethercat/et1100_et1200.htm
The sensor is a PT100, an analogue input sampled independently on the I/O
protocol. In this case of ET1100 it is EtherCAT. The nature of the
communication is that I/O to the master and sampling can be asynchronous or
triggered by communication I/O etc. In short, it is tasking, shared memory,
barriers and other "nice" stuff.
This is clearly all over the top for a fridge right now. But this is not so
distant future. A telephone is already a personal computer with all bells
and whistles. So any household device will become.
It may be funny, but yes, to service one bit of data of an actuator or
sensor you will have a whole computer attached to it wielding the power of
a workstation in early 90's.
