my edits since yesterday
Love your superhouse video series. It is extremely well presented and very concise. Your Superhouse setup is amazing. Very impressive. I was hoping to start a conversation here to pick your brain further.
I am involved with a new build for a Victorian based house which is scheduled to be finished in the next 12 months. Which I am interested in setting up in a similar fashion to Superhouse. I have some background with electronics and Arduino, and openhab and mqtt look very simple in regards to logic workings. I am a novice with Home automation though. So the main gist of my queries is related more to the hardware setups.
So I will probably rant abit my understandings of how you have things setup and interlace some questions throughout, which I am trying to decipher. If you don’t mind of course…
So I understand the Distribution Board setup you have, in a broad sense. That being the centralised Star wiring schema for the load devices.
- I believe that is referred to as the LV lines? Over 50 vac but under 1000vac is low voltage, which is where the 240v lands.
I get how they are activated at the 12v side via the ethermega however. Ahh episode 24 about 9 mins, (no longer lunchbox) this then connects DIN–Ethermega(lunchbox mega)–Signal(pulls 5v to ground)–MQTT–Openhab and giving you the network controlled publishes and subscribes. I think… I need to review that some more. AHH lunchbox is shiny now and exits simply via Cat5/6 to to patch panel.
You have those devices going into the din relays, what are the other options here?
Why are they dipole? I need to look into single and dipole relays, that is over my head currently, I guess I don’t understand the need to loop the active and neutral?
Do those relays allow you to dim/ramp the light intensity? I assume so, but it wasn’t clear in your videos.
Do those relays allow you to control ceiling fans? Do you need a din fan capacitor/controller to do that or is there some other solution? If you have ceiling fans how are you controlling the switching for them? As an add on to that how are you controlling your reverse cycle AC - The remotes are very noticeable in your videos.
You mention blinds as load devices. Can you expand on that in a future episode? how many blinds/relays are you using? Are you using the dooya motors or something else? As a fellow Melbournian I am interested in your solution to blind controls. This contrasts your window openers/linbus system, which I believe you wired up via the cat5.
Lastly on the DB and sub DB, all your GPO/sockets are still from the main DB box at the front of the house in a daisy chain circuits? That seems to be how its done to my understanding, even in cbus. I could be mistaken though. I know less than nothing about cbus
So that gets us to the switch side which you have wired via cat5, with upto 4 gang max per cable, then into your awesome rack mount Arduino button controllers. Again this is the Star wire schema. It sounds amazing and really light weight.
This would commonly be referred to as the ELV lines ((well POE really isn’t it, not ELV as such like between the switchboard lunchbox mega)) so I guess not ELV.
How does this contrast to CBUS switch wiring? Clipsal Iconic with the mech 40s seems to go back to daisy chaining and using bluetooth to manage the switches, which seems like alot of extra radio signals around for interference/jamming. So I guess I am basically saying here I don’t understand how cbus wire the switches and my google-fu is not being helpful. if you can shed some insight onto how cbus normally wire switches for home automation that would be most beneficial to myself as a HA novice.
relates to Q2-Q4 Can your switches be used to dim/ramp the lighting and or control ceiling fans in your current setup. My understanding is you can do it via openhab with timers and scenes. I wasn’t clear on if you are doing these types of things, and if you have the capability of doing it directly from the switches.
How would your setup go for passing building inspections on a new build? Would they basically just ignore your switches because they are ELV/POE or something? Would a typical building inspector pass a building with no light switches? I see how the ELV in switchboard passes now double shielded cat cable
What would you do differently in a new build while you have frame access now that you have so much experience to build on? e.g. Would you do something like have a whole house battery system for UPS provisioning? failsafe your light switches somehow?
Are your alarm and camera systems integrating to openhab either as sensor inputs for automation or using openhab to control those devices? I assume you are still running the Annke cameras.
You briefly mention Nodered, is that something you are using in this system? It seems like just openhab and mqtt from the rest of your explanations. or perhaps not, flow based programming I have less of an idea about than cbus. HA, I don’t think I need to know this, YET
You stated you had an electrician wire all this up. Can you pass on his contact details if he is interested in more work?
Thanks for taking the time of creating this resource, it is extremely valuable. Oh and if I have over looked the answers from the comments on youtube I apologise, I haven’t looked there too deeply yet. Information overload was kicking in, it was handy for myself to write this all down Sorry for the essay.
