In spite of having had my share of difficulties and hickups with openHAB, most of it actually went pretty well and I now have a system that actually does pretty much what I want. Apart from some things like weather and astro etc that have their own bindings, I mostly use MQTT, as I build most of the peripheral hardware myself (ESP8266, Arduino, with DIY interfaces). To integrate a pre openhab, pre-ESP automation system I also included 433 MHz for communication.
I could not have gotten so far without the help of this community and ofcourse without the work of the very makers of OpenHab.
It might be natural that we mostly publish posts about the problems we encounter so let me definitely celebrate the success as well and really, there is more success than problems.
Initially ofcourse I just started to use openhab to report statusses to me and to be able to switch things on and off.
My pre-openhab system did a lot of control as well, (e.g. imitate my presence when I was not home) and that is a function I now more and more start to build into openhab and therefore I will ned to dive into the ârulesâ more and more.
Though I am quite OK with C++ and a hoist of other languages, Java is not one of them, so I foresee a steep curve with the rules again, but learning is never bad.
Anyway, I now have a system that controls/regulates:
The lights in my house (the âHello Worldâ of home automation)
My heating
Knows my day to day habits and anticipates to that
Simulates my presence when I am away (to deter burglars, still have to find a good random function for my rules)
Gards my house, up to including letting a dog bark at specific times
Controls my garden irrigation
tells me when it is time to plant specific crop (carrots e.g. need the soil to be > 7 degrees C for planting, a ds18B20, an esp and a rule tell me)
Controls my aquaponics systems
Keeps tabs on my chickens (currently trying to build something that indicates an egg being layed and to automate the feeder)
Even tells me when a mouse trap cought a mouse.
sends me mai updates on important happenings (e.g. someone at the door, a window was left open )
And⊠not unimportant: as i get a bit older and sometimes forgetful, it keeps an on my oven, cooking stove and fireplace to alert me if they stay on too long (i.e., I forgot to switch them off). That is still in an experimental fase though
Have been able to build similar stuff for others (like a showertime controller).
Anyway, it is yet far from complete, but if I had bought it commercially (if available at all) it would have cost me thousands and I probably would have to pay some annual subscription fee.
In spite of my share of frustrations I had fun building it and at my age (>60) it is always good to keep the brain busy.
Now all i need is face recognition of known burglars and attach that to a souped up cattle prod, that I connect to a servo, all controlled by OpenHab.
Anyway, it is probably clear that I am very happy with Openhab and thanks everybody who made it possible. I am sure I am gonna have more questions in the future
