Aeotec Nano switch fitting



The Aeotec nano switch looks simple enough to fit, I just need to establish which wires go where.
I found a picture on the internet that shows this better, but I have 2 red wires going into C and 1 wire going into 1.

Now I am not an electrician, but I need to check that the 2 wires in C,  I class as Live for the purposes of connecting to the Aeotec switch and the single wire in 1 is the load.
If that is correct, I can get this wired up


The picture below shows a single nano switch



  • The current wire labelled C which goes into the light switch , needs to be plugged into the port labelled L on the nano switch
  • The neutral that is currently on the left picture and unused needs to be connected into the port N on the nano switch
  • The L and IN need to be bridged on the nano switch
  • The wire that goes into 1 on the light switch needs to plug into OUT on the nano switch

Home Automation controller Home automation assistant

Everyone likes the sound of automating their house, but the reality differs quite a bit, and its a minefield of options, with so many Chinese widgets and complicated setups, many of which aren't going to work in your country.

I have taken it upon myself to get some of the lights automated in my house. This started off as a "lets buy an amazon echo to give one of the kids an alarm clock" to using it to voice activate the lights.

So i have ordered the following bits and I have an Amazon Echo + i bought in a sale.


  •  Aeotec in wall switch light controller
  • Aeotec Z-Wave stick
  • 2 x Phillips Hue lightbulb

I have an old raspberry Pi lying around, and this might end up being where i plug my Z-Wave stick into.

My house has lots of down lights ( about 60 ), and i replaced them with LED bulbs not so long ago, so i am loathed to replace them all with LED smart lights because of the cost. Not to mention that the current bulbs are R80, and no-one makes an R80 smart bulb yet.
 I have been keeping my eyes open for the right solution that is both cheap enough and simple enough that i can set it up. I will start with the lights, and only in a single room, and go onwards from there. The main issue was lack of light switches that are certified in New Zealand. There are plenty internationally, but they are either the wrong dimensions or not approved for use here. The only one i have found is the Wullian light switch, about $100 that replaces the existing one. Its not plain enough , but would probably look ok in my house. The issue is when i get to 2 way switches, which i believe this cannot handle. The Aeotec product can.

I am planning ( after much research) to use Home Assistant as my controller, and plug the Z-wave stick into this, copy some scripts off the internet and away we go.

Just need to wait until the goodies turn up and i can start playing.

I fished out my old Raspberry Pi 1B and using the guide on the home automation website, I installed hass.io onto the SD card and booted the pi up, so far that's easy.
Getting further, I don't have the DNS name registered, so the configurator won't load from the sidebar, I need to goto the UI page under hass.io, so looking at going back to the original file to set some additional security and network details

I spent agees messing with my TV settings and haven't got anywhere. My Z Stick has arrived and I have inserted it into the PI and its showing up in Hass.io. SO now I need to get the nano switch installed.

Android Update - Broken

I have a Galaxy s5 and since the recent Lollipop update I find the lock screen has small rectangle over some of the keypad letters, this extends to text messages and various other items with fonts.
In addition to this, the mail app will crash throughout the day.

I have cleared the cache and rebooted the phone and this will clear it for a while, but the same issue returns. Its amazing how an update that has a bug like this that is pretty visible can make it out into the market place.Especially on something like that Galaxy S5 which was Samsung's flagship phone until the s6 came out.

Very tempted to remove this update and wait for a fix
