How to install smart switches


I replaced some old dumb light switches with new smart light switches. 


Note 1:Before I go through the steps, here is a little bit of important information to know.  There may be several wires required to make the new switch connect - here is the definition of what you should see available in the housing for the switch.

 Smart light Switch= In my case, this is a wall light switch that has a radio that can be connected ted to a Hub for remote control or for programming on/off/dimmer based upon triggers. The protocol of the radio is z-wave in my case.

 Line= always hot wire - this is the source of current to the switch.

 Load=wire that goes to light out the other side of the switch and is only hot when the switch is turned on.

 Neutral =  White wire (in my house) that carries a current back to the source for the unbalanced portion of the load

 Ground wire= the wire that grounds the circuit.

 Note 2: I've only installed z-wave switches with a neutral wire.  If your house is older & you don't have a neutral wire this blog may not help you.  

Note 3: Make sure someone is around to check on you should something bad happen with electricity.  Know that these instructions apply to my residential wiring in the US.
Here are the steps I took in order.

Disclaimer: This blog entry is not intended to imply that these activities can be performed by unskilled professionals, instead it is simply a reporting of my findings when installing these switches. Consult an electrician for help. 

 Step 1 - Turn the existing wall switch into the off position & use a voltage tester to see what wire has a live current.  The one that doesn't is the load.  I labeled to be sure I didn't confuse them.

 Step 2- Turn off the power from the circuit breaker that controls that switch and make sure it is off. Double check with the voltage tester that the electricity is off.

 Step 3 -Disconnect the old switch and connect the new switch - putting the wires in the appropriate connections securely.  Some switches have pigtails, but mine did not. 

 Step 4 - Turn the power back on at the breaker and go test the switch works to control the light.  

 Step 5 - Add the switch to your hub controller

 DONE!

Flushing a water heater.

  I learned from a plumber that I could be flushing my 40 gallon gas water heater in a more effective way.  Here is the process as it was described to me.  Hook up a hose to the water heater and run it to a bath tub or out a window or door to drain. Turn on the valve a little so the water heat starts to flush & check that water is coming out the other end without a problem.  ***NOTE - Don't turn off the water or the gas, or open the air valve. If there is no leaking or drain issue, turn the water all the way on for 5 minutes and let it run.  This can cause a white substance to build up in the drain area.  This is supposedly calcium that has accumulated in the tank. If the calcium/flush substance is no longer coming out, turn off the water valve and disconnect the hose. Leave a note on the water heater or make a record with the date of the flush & schedule another flush in no more than a year. You are done. Another note - We have a water sof...

Dancratic method in a nutshell

With the help of good friends, I've developed an approach to conversation over the last couple of decades.  In this blog I'm trying to forge that approach into a system that I'm calling the Dancratic method. PREMISE : Everything should be able to be questioned.  If it doesn't hold up to scrutiny it should be considered theoretical at best. i.e. You should be able to question 2+2= 5 and adhere to the rules below. Even the most volatile topics can be discussed with civility if  followed properly.   Dancratic method is a specific application of Socratic method.  Instead of a group discussion lead by a teacher or leader, these rules can facilitate 1 on 1 conversation for productive truth seeking.  There is no persuasive element to Dancratic rules.   GOAL : The goal is learning something new.  Perhaps understanding a different perspective a little more.  There is no winning, and no losing unless you break a rule- then everyone loses...
