Nefit Easy™

[kraades]

I am not familiar with Node-RED but is it also possible to "exec" bin/easy directly without the intermediate bash scripts?

[jannl]

Yes, you only need to set the 3 environment variables.

[pepijn]

You can also add them as command line parameters.

[jannl]

Correct. When using a crontab script you will need te set them in the script.

[pepijn]

This is how it looks like within Domoticz:

[jannl]

How often do you refresh?

[pepijn]

How often do you refresh?

Temperature : 30 seconds
Status Code : 10 seconds
Pressure : 5 min

The setpoint is changed real-time, if some other device changed the setpoint (thermostat, clock program, Easy app) the setpoint in Domoticz will be updated when updating the temperature.

[jannl]

That should be sufficient indeed. Gives me something to do next week.

[kraades]

Great! I will give a try later this week.

[pepijn]

Here is my current Node-RED flow, have fun.

I now update the values once a minute, is the easiest frequency with crontab.
One file to update them all.

[dorenberg]

Maybe somebody can help me.

Want to have the same as pepijn has but I am already stuck with upgrading Node.js to version 5.3.0. With the command sudo cp -R * /usr/local/ I get the following error.


cp: cannot create regular file `/usr/local/bin/node': Text file busy


Cannot delete or change permissions of this file.

Can somebody help me with this?

[pepijn]

You need to stop all running node processes (like node red). Please note that nodejs 4 or higher will break the homebridge support

[kraades]

Robert Klep has developed a client in nodejs that can access the Nefit Easy™ thermostat. It would be great if this can be integrated natively in Domoticz.

[geezerrr]

Hope someone can make a wiki once there is a stable solution for the Nefit easy. I'm not a programmer but learning by the day!!. Unfortunately I'm stuck with the red-node part..

I'm getting syntax errors., so for now I give up... Thanx in advance for all the hard work.

Can you execute the scripts manualy?

[geezerrr]

The example script was working.. But I need to set my serial;acces-key and code each time I ssh to my Pi 2..

I think I have not enough program skills to solve it myselve

[pepijn]

Thats why you need to edit the script and replace the XXXX's

[geezerrr]

Of course I've replaced the XXX's

I think it has to do that i run Dz on the prepared image and the Nefit client is installed in home/Pi/Nefit-easy-client. And not in opt/Nefit/nefit-easy

[pepijn]

If you place the scripts in a different location you have to edit the 'EXEC' nodes in Node-RED.
Do you have MQTT enabled on your Domoticz setup?
