I am new to Fhem. I like to know that how can I access Fhem api using node js. I am creating my application for home automation on node js with front end in angular. I will host my application over Orange Pi. I want to communicate with Fhem in my node application and I do not know how to do that.
I am looking for Fhem api that i can hit from my node application and perform my relevant action. For example setting new devices in Fhem through node.Teach them. Get all list of devices available. Turn on/off switches, lights.
I want to be able to add EnOcean based devices
I want to be able to add multiple floors to a building
I want to be able to add multiple rooms to a floor
I want to be able to add multiple products to a room
I want to be able to change (add, delete, move) a product from one room to the other
The main question is how to connect Fhem with node and perform this action. Is there any api exposed from Fhem to do these action
You can always control Fhem either with http(s)/curl or with telnet or nc. You will have to cope with authentication and csrfToken, but it should be no problem for you.
Some hints here:

https://wiki.fhem.de/wiki/CsrfToken-HowTo
there is a nose module to do than somewhere on the forum or on github.
if you want to do it yourself you can also look at alexa-fhem and the homebridge-fhem modules. they are both for node.js
Do you mean this one? https://github.com/winne27/fhem.js/tree/master
that is one of them. there is also a rest api patch for fhemweb somewhere in the forum.
Thanks a lot for the reply. It was great help. Moreover I have few more questions If you guys can help up.
Is there any OrangePi simulator I can use before acutally purchasing a OrangePI device. I searched but was unable to find one.
Secondly, In my application there will be a learning phase. in which the actuators of the software are connected to the end device (e.g. a heater) for the very first time and where the software sets up a connection to the product that needs to be managed. Is there any way to manage new connection by our self. Not by Fhem?
What i have understood so far ever device need to configured first in Fhem.
I Like to know few basic thing for connection of my angular front End with Fhem. I have read The control of the devices is a simple HTTP call to FHEM.An code example will be real help I donnot know how to do that. Any blog or recent post can great help/
How did you create the connection to FHEM?
What call will I make to know list of devices, In what format it will be? and What it will return to me.What format the result will be in?
Mainly I want to know how to communicate with fhem from a simple node application. What will get and post URL to hit fhem to retirve information.what will be its format.
