Can the EZIO4O be programmed using X10 commands? Specifically I’d like to program the relays’ timers using X10 commands to avoid investing in Insteon just yet. I searched the Homeseer site for a X10-based plug-in for EZIOxx but I think that all the plug-ins and scripts are based on Insteon.
Sorry, but timer programming can not be done through X10. Consider investing in a Smarthome PLC or Simplehomenet EZSrve to interface a PC or browser application to not only your EZIO4O but to an entire INSTEON/X10 network.
A PLC is a controller than can plug into a PC, and is supported by 3rd part software. Depending on your environment, there are some free options out there, such as inhomefre (windows): http://www.cwfam.com/PublicInsteon/index.html
The PLC will sell contain timers, so you do not need to leave your PC on.
