I am currently looking into openHAB for a possible solution for our home automation. I do have an unused laptop that could easily be used for this.
What I would like to have control over:
There are different devices manufactured by different companies for each of the above. So its a question of finding the best hardware.
All of this needs to be accessible via an app on my phone.
notifications for alarms (smoke detectors)
Seems like all of the above is provided by openHAB combined with a VPN solution, which is great!
Updates on the selected hardware and the integration will be given here in the future, stay tuned!
