Home automation with QNAP TS-251+-8G server and OpenRemote - is it possible?

I am planning to build a detached house and am therefore considering automating it. When looking for useful information on the subject, I have not found specific answers to some questions. I still have some time, but I would like to start planning calmly already.

Let me start by saying that I am in the process of buying a QNAP TS-251+-8G us server for my media centre. Is there any possibility of using/relying on it for home automation? There is something like OpenRemote, but I don't know if this is the right solution. Obviously I would like the solution to be as much as possible based on wired connections.

I envisage automation in such a way that there is a touch panel on the wall with which I can control and read out information. I would also like to be able to access the same functions from other devices both on and off the local network. Access from mobile devices should require the device to be added to trusted or similar security.

The panel on the wall should:
-show the temperature from one maximum of two sensors in the house
-show the temperature as it is on the cooker (Is it even possible to connect/control the cooker? The cooker will be a pellet / eco-pea cooker with a feeder)
-show the temperature outside
-interact with the video intercom
-control the gate, garage door
-view one or two cameras from outside
-etc

In addition, a couple of sensors for smoke, flooding, open doors, etc. Ideally, the solution should be flexible and relatively programmable so that I can adjust it to my requirements during implementation, e.g. when opening the garage door the light inside the garage will switch on if a certain condition is met, etc.

I would very much appreciate your help in finding the devices, protocols and general method of implementing the main ideas.

You should be able to safely put openHAB on QNAP - read up on it, it might be the solution for you.

If you write yourself software to integrate different sensors and systems then why not....

openHAB - Features
Some things are supported. But I'm betting that actually quite a lot of stuff would have to be carved out yourself.

Are you able to suggest any other solution of this type? Open source or inexpensive?

I'm guessing you're going to insure the house - then a real alarm system. You can connect different types of sensors to it, ethernet module....
As far as the image from cameras is concerned - you can use a DVR (or IP cameras) to display the image on the alarm system keypad (in addition to the network preview).
Read about Integra 64, for example.
Another interesting solution is Fibaro.
And finally, there is still Ardunio.

No need to write everything yourself;)
Nice overview of home automation systems: https://www.mysensors.org/controller/
I personally recommend iobroker. However, it is worth reviewing what system what capabilities / shortcomings it has.

A reminder to persistently secure the main circuits with the possibility of emergency control bypassing the system.

As already written here - certain systems should be able to operate autonomously and be integrated with home automation, e.g:
- Alarm - for the reasons written about (insurance) and its importance - it is a great source of data for automation by the way.
- CH/CWU - such systems have their own logic (even simple thermostats) and should operate autonomously - home automation should at most change the settings and nothing more.

At home, I run OpenHab, which I integrate with:
- alarm (Satel) - parameter reading + arming, however disarming is only possible from Satel itself + gate control
- boiler (via MODBUS) - change of parameters such as set temperature, operation mode
- with 1Wire sensors - about 20 sensors on the bus - room temperatures + additional measurements on the CH/CWU installation
- with mysensors - measurements where I couldn't reach after 1wire + current measurement at the entrance to the building
- lED light control - own dimmers with Homie library
- control of audio/video devices in the living room - integration via IP + infrared transmitter also controlled via IP
- roller shutter controller - I am testing a bleBox - if it works I will install another one
- iP cameras - (zoneminder) - OpenHab is only used to display the current image

In the plans:
- radiator thermostats - I don't know what kind and what integration

Basic assumption when building - if OH stops working, it should be possible to function in the house.

A DVR would be useful for the cameras - cameras alone are pointless.

For a gate it's a dedicated controller - you can control it by short-circuiting the input and get the open/close status from the limit switch.

The control can be done e.g. with RM85 or bistable relays - then all you need is a control cable to e.g. light switches.

Automated heating - if you have a small house, there's no point, you adjust the radiators once and don't have to change them for the whole winter, or you can regulate the temperature with, for example, a four-way valve. If you have a coal-fired cooker, you still need to check it at least once a day, so you can adjust the temperature on occasion.

The last thing which almost nobody remembers is the fire safety of the boiler room.
Type "sprinkler" into Olx and install two or more, as it costs next to nothing, and I've seen a lot of houses burn down because of boiler rooms, which is why I'm reminding you of this.

enceladuse , are you able to manually switch on the lights , directly in the power circuits, bypassing the controls/?

Yes. Because I was basing it on the existing installation I did it the simplest way possible - for the time being at the expense of functionality. I didn't rework the existing installation, the controller is plugged in behind a normal wall switch, which cuts off power to it.
The dimmer/transmitter goes high when starting and if it doesn't connect to the control system then the light is on - it can only be turned off with the power switch - we are not dependent on the control system. This has some disadvantages - when the system is running I cannot turn the light on from this switch.

For this reason, I am now testing a solution with short reboot detection and relay/dimmer status stored on Flash (I use ESP). That is - if I quickly switch off/on the power to the module then the controller state will change to the opposite state at the same time informing the control panel. If there is no control panel available - everything works normally. Only the switch on the wall will have to be changed to a monostable.
I am still thinking about this. If the system does not pass my wife's acceptance tests - I will switch to z-wave.

And one more general remark - if you don't have a technical jam, don't load yourself up with proprietary home automation games - buy a ready-made solution. You'll spend more money, there won't be as much satisfaction, but your family won't curse you

I suggest you read https://plcstore.pl/ and phone or skype. I have appliances from them and they helped me design the installation.
