openHAB seems to be right what I am searching for – a powerful solution for building automatization and integration which is independent from specific protocols or vendors.
Totally new to openHAB I have been reading many threads in the Forum as well as the beginner tutorial and several others including third party sources about iot. I am struggling a bit at the widths of the system and the many options to get the same problems solved. In other means I am a bit lost and need advice for best practices and choice of hardware and software to use. For sure you have to be a bit tech affine for openHAB even the graphic interface is more powerfull in 2.x.
Would be really nice if you could comment on below.
So far there is a test Intel NUC Linux environment running (Z-Stick Gen5) with a few z-Wave things to test. Open HAB 2.2
The plan is to create home automation for a larger building with different use zones such as:
• Typical living area (living, room, kitchen, bath room, bed rooms, child rooms etc)
• Storage rooms
• General rooms like stair case etc.
Given structure and surroundings
• The building is equipped with LAN in most rooms (1GB in most cases PoE).
• Network hardware Ubiquity Unifi only
• WLAN is available in the whole building via several Unifi AC-Pro
• Many rooms 4 wire cables unused left over from previous telephone system
• Cable channels available in many rooms> relatively easy option to install additional cables
• 3cx phone system fully SIP based, telephones mainly Snom D345
• Virtualized powerful server system
• All rooms radiators with thermostatic heads
• Integrated system > room temperature, light, IT, sound and tv system, presence, system health…
• No cloud server!
• Stable solution
• Basic functions must work even the Server would fail
- switch on and off main lights
- set temperatures at radiators
- open and close window blinds
- switch off hull protection or at least intrusion signalling (siren i. e.)
• In normal use functions etc. to be controlled mainly via HTML5 web page and apps as smart phones, tablets and PC are widely available
• Track power consumption, temperatures etc.
• Being able to control out of the internet > VPN already available
• Different few on the system:
- by floor and room
- by type of thing > heating, lights, …
- alarm panel
What I have found so far
• Z-Wave thermostatic radiator heads seem to be a nice solution because of Z-Wave mesh technology and low power consumption compared to i. e. Wifi. Prices in the meantime at or below Homematic (IP) so mesh technology, nicer look, more options across different vendors makes me opt Z-Wave at priority 1
• 220 V based Z-Wave things needed in order to create stable mesh
• Z-Wave switches used for main lights will provide control via existing light switches even the openHAB server would fail
• Several other standards for lights available at lower cost
- Sonoff > Wifi based does not work if IT fails MQTT broker needed
- Mi-light > 2,4 GHz proprietary, no back channel, API available direct Binding available
• Cable based systems are probably most fail save and stable
- KNX seems to be widely supported and the general choice of the professional electricians. Quite expensive
- 1-Wire seems to be an interesting solution > no further investigation at my end so far
• Best practice to set up system > seems text based is still most powerfull while the journey seems to go toward graphic interfaces > what is the difference in the outcome? i. e. where is the settings stored? Pros and Cons? Have theVisual Studio Code set up already but have nod deeper understanding of coding even the basic functions seem to be quite logic.
• Best visualization > HabPanel?
A long list sorry about this it would be very nice if the many experts in this forum could give advice and comment on above. Thank you very much for your kind assistance
