Nefit Easy™

[BartdaMan]

I cannot remember exactly. It was not so difficult. I remember I had to log out as pi user and log in as root. And then log in as pi user again and change to the /home/pi folder for installation of the easy server.

Whenever I have problems connecting to the Nefit with the easy app on android, I reboot domoticz and everything works again. May be I need to create a easy server restart on the pi.

That's funny, because when I have Domoticz/Raspberry connection problems (maybe 1x per week) I disconnect the thermostat from the wall connector and refit it. It then reboots which also solves the Domoticz connection problem.

[jannl]

I know, but rebooting domoticz is way easier. I created a switch for that long time ago

[mvveelen]

I'm lost.... can someone point me to the solution?

I've been using the easy-server for a long while on my Synology and everything was fine. I just rebooted the Synology and there is no data transferred to Domoticz.

The server is running and starts when the Synology starts:

Code: Select all

root@DiskStation:~# ps wax | grep easy
16699 pts/13   Rl     0:03 node /usr/local/bin/easy-server --serial=xxx --password=xxx --access-key=xxx --host=127.0.0.1 --port=3000
16713 pts/13   S+     0:00 grep --color=auto easy

The hardware in Domoticz has exactly the same settings (IP and port)

Killing the process and restarting the easy-server doesn't help:

Code: Select all

nohup easy-server --serial=xxx --password=xxx --access-key=xxx --host=127.0.0.1 --port=3000 &>/dev/null &

What can I do to get the data transferred to the devices again? Last update is a few hours ago. I even tried to replace the current DB wit a DB from yesterday: no result.

The log shows:

Code: Select all

2016-10-31 22:06:24.601 Error: NefitEasy: Invalid data received (main)!

Edit:

I feel stupid.....

The Nefit was OFF, so no data was transferred. When I discovered this and turned the Nefit ON, all data came back..... Stupid, stupid, stupid. But hey, it works again

OK,

I've been in contact with Robert Klep and he has updated his nefit-easy-cli. Now I can switch the hot water ON or OFF, regardless of the mode it is in (program or manual). This can be done via CLI:

Code: Select all

easy --serial=xxxx --password=xxxx --access-key=xxxx hot-water-supply on
easy --serial=xxxx --password=xxxx --access-key=xxxx hot-water-supply off

I asked Gizmocuz to have a look at it. I would love to have this available as a regular switch (whereas the current hot water switch doesn't work for me).
Or else I have to make a script which I can use to toggle the hot water.

[jannl]

Can't you put this in the on/off action of a switch?

[mvveelen]

Not sure if that's possible, I prefer to have it built in as a switch. But if that isn't going to happen, then I can try to make a workaround

Edit:

For now (I still hope Gizmocuz can build this into Domoticz) I made a (dummy) switch where I use:

the 'On Action':

Code: Select all

script:///volume1/@appstore/domoticz/var/scripts/python/hotwater_on.py

and 'Off Action':

Code: Select all

script:///volume1/@appstore/domoticz/var/scripts/python/hotwater_off.py

The python scripts:

hotwater_on.py:

Code: Select all

#!/bin/sh
easy --serial=yourserial --password=yourpassw --access-key=youracckey hot-water-supply on

hotwater_off.py

Code: Select all

#!/bin/sh
easy --serial=yourserial --password=yourpassw --access-key=youracckey hot-water-supply off

Don't forget to:

chmod +x hotwater_on.py
chmod +x hotwater_off.py

Works like a charm !

What exactly can you switch now?
Boiler on/off?
Or can you really switch off hot water supply? That would be nice if someone is taking a shower for too long time...

[mvveelen]

I can switch on/off the hot water supply.....

[BartdaMan]

Should the hotwater_off.py not read:

Code: Select all

#!/bin/sh
easy --serial=yourserial --password=yourpassw --access-key=youracckey hot-water-supply off

So off instead of on?

[mvveelen]

Yes. Wrong copy-paste.... I'll correct it

[BartdaMan]

Alright, it didn't work for me at first, until I read your earlier post carefully. So I had to update Robert Klep's Nefit-easy CLI.
And now indeed, works like a charm.

But I still don't understand why this could be useful. What are you using it for?

[mvveelen]

The Hot Water (in my situation) "follows" the program. But there is no need to have hot water available whenever I'm at home. So I want to make a dependancy: if the waterflow > 1 and light in bathroom = ON, etc. Perhaps it might save some energy

Hi,

How do i upgrade my nefit-easy-server? I'm running version 2.1.0 at the moment.
Can it be done in the command-line on my Pi?
I used npm i nefit-easy-http-server -g to install the nefit-easy-server but when i do that again version 2.1.0 is installed.

regards,
Joop

Maybe 2-3 times per month the Nefit easy server hangs on my Raspi3. I then have to reboot Domoticz and everything works again.
Does anyone have similar problem?
Is there a fix?
Or a workaround script e.g. if connection time-out then reboot Domoticz?

This is a known issue, see earlier messages in this topic. I don't think it's an Domoticz issue, just refitting the thermostat also solves the problem. For me I just switch off/on the Nefit adapter between the Easy and the boiler if I see timeout messages in the Domoticz log.

Can someone help me with some basic Nefit Easy stuff?
I have a scene "Go to bed" to switch of all light in de living room and turn on the lights in tbe bedroom.
Now i try to override the Nefit Easy program and set a manual temperature to save gas usage. My Nefit Easy programs sets temperature to 17.5 degrees celcius on 22:30 i want to set it to 17.5 degrees when i activate the scene.

I tried to send the command:
curl -XPOST http://127.0.0.1:3000/bridge/heatingCir ... RoomManual -d '{"value":18 degrees}' -H 'Content-Type: application/json'

It says "OK" but temperature is not set to

Have you added the Nefit Easy as Hardware? That should give you devices you can use to set the desired behavior.

Yes, i have the Nefit Easy as hardware in Domoticz but there is no option to control temperature when using a scene.
