Hello,
so the goal for my Samsung AC solution was to have an automation for cooling down the room temperatures automatically. I have a small boy and the room temperature in our bedroom should be right when he is going to bed. I don´t want to turn on the AC when he is sleeping in the same room. So for sure I would forget from time to time to turn on the AC to cool the room down in advance - that´s why I was looking for an automation.
I´m using a Split Samsung AC system with 3 indoor units - model “Windfree”. In first step I installed the Samsung Smart Things app on my mobile phone and registered all AC devices.
Finally I started to read a lot instructions of Rest API and in general the documentation for the Smart Things Rest API to get used to it.
Here are two screenshots of my sitemap (not integrated in OH 3 UI for now - it´s on my to do list) which i´m using on my mobile (I´m from Austria so everything is in German):
I implemented a general switch for AC automation and also one for every AC unit. If I turn on the switch then the temperature gets monitored automatically and if the setpoint is lower than the actual temperature the AC turns on - and off again (of course) if the setpoint is reached.
Therefore I´m not using a hysterese but the average temperature of the last 45 minutes.
I´m also able to read the actual temperature set by remote directly from the AC, change the operating mode (normal, windfree, fast and windfreesleep were the one I would like to use), turn the AC´s on and off and also get an status update if one of the AC´s was turned on also by remote. Therefore I have some update rules running.
I´m not fully done now - sometimes my rules are not working 100% and also the visualisation is work in progress.
So that´s what I can offer to you guys. If you are interested in how i achieved this I can share all the details.
Cheers,
Mario
