Am I correct that this is basically the equivalent of a do-it-yourself
thermostat?

And as a result if I do this then the operation of my pool heating
system becomes dependent upon my having a functioning ELK-M1G system?

If so, that seems like a reliability risk.  It seemed to me that beauty
of the RCS device was that it was a freestanding thermostat; if the
rest of my home automation system crashed I could just keep using the
thermostats manually.

Why was the RCS device discontinued?
