Success! I just finished wiring up my gas fireplace.up to SmartThings tonight.
My fireplace as a small on/off switch on the side which is basically just a contact switch. Complete the connect and the fireplace goes on. "It would be easy enough to replace the switch with a z-wave relay, but one thing I have striven for when implementing SmartThings is to ensure that whatever I put in place can not be controlled ONLY via Smartthings. It still has to have a manual control. So, how to put in a relay but still have a functional on/off switch on the side of the fireplace?
This little baby has the option to connect an external switch. So, connect power to the relay, then the replay control wires replace the on/off switch wires. Finally, the switch wires go to the external switch contacts.
Now it works thusly: The relay can be turned on/off via SmartThings, which turns on or off the fireplace. The switch on the side can also be used to turn on or off the fireplace.
Because the relay over rides the physical switch, the switch can get “out of sync” with the actual fire place. For example, if I turn on the fireplace with the switch, and then use SmartThings to turn off the fireplace, the physical switch is still in the on position. Simply turning the switch off, and then back on with restart the fireplace.
Similarly, if I turn on the fireplace via SmartThings when the switch if still off, simply toggling the physical switch on and then back off will turn off the fireplace.
So, one more “things” is gotten smart! Now… how do I my snowblower??
