In my opinion Node-Red is not a script but IBM's way of connecting IoT. But you are free to build native support into Domoticz :)

The bash scripts in the example above have no error handeling for example they will start multiple times and have high CPU load. That's why creating a real node is a way better solution.

Pepijn, can you consider a solution with the option to exclude the pressure data.
My CV does not support this date. Obviously i can exclude the pressure sensor i Domoticz.
But in that case the date request is still send to the easy and why ask for data when its not needed.

Thx

Just delete the pressure nodes from your node-red flow :)

According to node-red.org it is build on node.js and propably takes more resources compared to my perl script, which indeed does not have too much error-handling at the time, but wrong values will not be handled, keeping them from getting into Domoticz.

node-red is most likely is some sort of code-generator, which is not bad of-course. Under the hood I suppose node-red also issue an "easy status"

And besides that, I like keeping it in perl.

That I did already. ;) And probably i will also remove the pressure code in Domoticz MQTT

Just saying that i hope your new version will also have option.

That's not the way a node red nose works. It's using the library part of the nefit-easy-client directly.
So it will not issue easy status commands.

Just shared my work in progress to others so they can benefit from it.

It will be a node red object that can be used in your own flows but I will provide a sample flow ;-)

Just curious do you have the pressure option within the Nefit App?

Nice! I tried the latest code again after my "upgrade" but I still have the " rbe" error in node-red
Overnight my issue fixed itself so now the updated node-red is working and Pepijns code is working including the rbe node.
I receive temp and status in Domoticz!

Some comments in the debug

Next, the set command does not result on a change on the Nefit easy.
I can set e new temperature in Domoticz which show the new temp.
But the thermostat does not show the new value thereafter.

Suggestion on what i can verify are appreciated.

I dont see it in the app and my CV does not support it. See https://github.com/robertklep/nefit-eas ... t/issues/6

Could this be related to thefollowing issue?
https://github.com/robertklep/nefit-eas ... -168806613
In other words you need the three commands to handle all situations (clock and manual).
At the moment the set temperature uses only two commands.

Well over here it works fine. I have a Bosch HRC II 35 at home. Pressure works and controlling the set point from domoticz results in a change in the thermostat.

Is your thermostat in a manual program, clock programmering or other?

To set temperature in timer (clock) mode you need 2 parameters.
Currently script works only when thermostat in manual mode, which is reasonable because in timer mode when next scheduled program are coming your set temperature gone.
What i did in mine situation just modify a script a littel bit in: npm\node_modules\nefit-easy-client\lib\commands.js (windows path, also i had some problems with windows interpretation of ' and " in a unix scripts so i did quick and dirty solution with aditional variable)

Code: Select all

  setTemperature(value) {
    var data = { value : Number(value) };
    var over_status = { value : "on" };  //place temperature override in 'clock' mode
    return Promise.all([
      this.put('/heatingCircuits/hc1/temperatureRoomManual',          data),
      this.put('/heatingCircuits/hc1/manualTempOverride/status', over_status), //place temperature override in 'clock' mode
      this.put('/heatingCircuits/hc1/manualTempOverride/temperature', data),
    ]).then(() => {
      return { status : 'ok' };
    });
  }

It is in the clock programming mode.

So if you change the script /opt/nefit/nefit-set to

Code: Select all

export NEFIT_SERIAL_NUMBER='XXXX'
export NEFIT_ACCESS_KEY='XXXX'
export NEFIT_PASSWORD='XXXX'

easy put /heatingCircuits/hc1/temperatureRoomManual \'{\"value\":$*}\'
easy put /heatingCircuits/hc1/manualTempOverride/status '{"value":"on"}'
easy put /heatingCircuits/hc1/manualTempOverride/temperature \'{\"value\":$*}\'
You can also change the setpoint when a clock program is used. But note, if the clock program changes the temperature (or you change it on the themostat/ easy app), te setpoint in Domoticz will not be changed.
I understood with the above script the nefit-set command should work with the clock program too.

Works good.
Robert today implementing some code changes regarding set temperature (to be able to work with clock mode as well) and introduce a server mode whcih also look reasonable because now for every command you use authentication every cycle which is not so good from server (bosch) side.
We should work like iOs/Android app: open connection -> authenticate > execute commands -> execute next command ... repeat.
