How do you integrate Tuya, Integra 64, Orbit, Dreamy and IP cameras into one Smart Home?

Hello, I am asking for help/hints on how to divide/construct a simple "SmartHome" system. I have a system at home based on Tuya components. I control this at the moment via the Tuya app scenes. I would like to expand this system with:
- touch panel scene selector
- IP videophone. Door module with camera
- several IP cameras
- Alarm system based on integra 64 board ( I have one at the moment)
- Irrigation Orbit controller / Dreamy hoover and mower (I have one at the moment but not connected to Tuya) - all have Alexa integration.

Obviously I would like to operate these lemmings via the said touch panel.

I've tried to figure it out myself but there are such a plethora of different device solutions that ultimately I have no idea how to go about it.

All I'm asking for is a hint, a diagram, what to look for, what solutions. I think that this is enough to start with.

Best regards, Marek

If you want to embrace all this, then take an interest in HomeAssistant. Except that tuya is not graceful. If possible, reprogram all tuya devices to OpenBeken (or Tasmota or ESP Home if using Espressif).
Buy an ETHM-1 Plus for the Integra and you will be able to integrate it. That's it in a nutshell, because the subject is difficult for an amateur, but I wish you luck.

Thanks for the hint.

I have already started HA on my NAS. All devices seem to have integrated nicely and I can use at least as much as before.
I am now struggling to get the "wall panel" on my tablet to work as a test ...

Please give me further advice:
- if not Tuya then which actuators will integrate nicely with HA operating over normal WIFI (no zigbee), any recommended company ?
- any "recommended" brand of indoor/outdoor cameras that integrate well with HA ?
- intercom. I found info that Reolink works nicely with HA. Does anyone have experience with this intercom ? Will I have something like a pop-up application on the wall panel with voice and video preview?

Regards,
M.
