I have dreams of an automated house, and so have been looking in to the various standards (Z-wave and Zigbee in particular).

 

Just how important is it going to be to pick the "right" (or even the wrong, but all the same) standard? I kind of had this idea starting out that everything would talk to everything else. However, while it would potentially be advantageous to control everything from a single point (e.g. openHAB), I'm not sure that opening up different apps to dim the lights or open the garage door is actually going to be all that difficult. And is likely to have a higher WAF in any event.

 

I appreciate that for the wireless stuff, individual devices can act as relays in a mesh network-style situation to increase range. And that I would need different controllers for different devices with different standards, but beyond that, is there anything I'm missing that would really point towards going with a single standard for everything?

 

If it helps, my dreams of automation include (this most certainly isn't going to happen all at once):

 

- mood lighting a la Philips Hue (which is Zigbee only)

 

- smart door locks I can lock/unlock remotely

 

- garage doors I can open/close remotely

 

- a smart alarm system I can monitor/deactivate remotely

 

- an oven I can start pre-heating remotely

 

- a central heating unit I can start/stop heating remotely

There are multiprotocol hubs like smartthings now Samsung:

Supports Zwave, ZigBee, WiFi, IFTT.

ZigBee and Zwave are close to open standards.

I'm struggling with the same thing,

 

Considering openHAB for doing some Z-Wave automation, similar to the above (except for oven); build my own alarm on it with some analog inputs and relays to control sirens

 

Interesting you mention Hue is Zigbee - I purchased a Hue Lightstrip Plus expecting to be able to connect it with openHAB via Z-wave, guess I'll need the Hue Hub after all?

 

Another platform I was interested in is https://home-assistant.io/ as it looks simpler, will be interesting to do some experimenting when Z-wave module arrives

IMHO you do not want to tie yourself to one particular vendor or protocol. No vendor or protocol out there covers everything you might want to automate. Any system needs to be able to integrate with a myriad of different products and protocols, to make anything remotely useful.

 

Consider your living room - you might have a RPi running Kodi, a Samsung smart TV, some lights controlled by Z-Wave/Hue, a Daikin heatpump, and a Squeezebox for music. There is nothing out there than can talk to all these out-of-the-box. And believe me once you start building your home automation system you want all of these things to be able to talk to one another. It is the integration of devices and writing of rules to manage this integration that moves you from *home automation* to *SMART home automation* - a big difference IMO!

 

This is why openHAB (and other open source systems like it) are so good - they allow everything to be tied together. It also means if someone comes along one day with a new protocol or device which blows the current crop out of the water, you don't have to replace everything in order to take advantage - you can keep your existing stuff and slowly migrate to the new protocol (assuming openHAB has integration of course). You are not locked into anything which in the long run will be a huge time and money saver.
