I am not in Texas, but I have an ecobee and during the set-up, there's a section where it identifies your local utility and asks you about opting into remote control for cost savings (which I declined). It's a standard mass-market thermostat and definitely has that functionality. Also worth noting that this was not some fine print sneaky thing, it was very plain language along the lines of "would you like to allow your local utility to remotely change your temperature settings in periods of peak demand in exchange for reduced energy prices?"
