Domoticz

I installed the nefit server

npm i nefit-easy-http-server -g

started it

created the Nefit Easy HTTP server over LAN interface

But when checking:

curl http://127.0.0.1:3000/bridge/ecus/rrc/uiStatus

I got the next messages:
Error: INVALID_RESPONSE

I unplugged the nefit easy, (reset) but this didn't work.

In domoticz I got the next messages in the log:
2017-02-09 21:29:38.890 Error: NefitEasy: Invalid data received (main)!
2017-02-09 21:30:09.088 Error: NefitEasy: Invalid data received! (Press)
2017-02-09 21:30:09.285 Error: NefitEasy: Invalid data received! (Gas)
2017-02-09 21:31:09.592 Error: NefitEasy: Invalid data received (main)!

Someone ideas how to solve this?

I have another question. According to Nefit, they don't save anything on their server, only some information about me, and the installation. So if some information is requested it should come from the easy. Some people got the information after resetting the easy, so seems to be right. But don't I need the IP adres of the easy in the settings? Or is that handled by the nefit server?

Posting your question in two topic's won't speedup the process

Sure you have set your environment variables?

NEFIT_PASSWORD=<password>
NEFIT_ACCESS_KEY=<your access key>
NEFIT_SERIAL_NUMBER=<your nefit serialnumber>

And if you start the server through a script, make sure the variables are set in the script, as well as the correct path to the needed binaries

I didn't use the environment variables, but a script with:

#!/bin/bash
/usr/bin/easy-server --serial=your-serial --access-key=your-access --password=your-password --host=127.0.0.1 >/dev/null

I saw I had an typo in my password. It didn't change the message on the curl, but the strange thing is, I see now in my domoticz log the next message:

Error: NefitEasy: Error getting http data!

After some trial and error I managed to get more error information.

After some trial and error I retyped the complete script. Now it's working. Probably there was some character which can't be seen in the code. Now it's working correctly in domoticz.

The curl still gives a INVALID_RESPONSE. So maybe that's not the correct way to test your connection.

Nothing wrong with the curl command when i execute it on my system

curl http://127.0.0.1:3000/bridge/ecus/rrc/uiStatus

{"id":"/ecus/rrc/uiStatus","type":"uiUpdate","recordable":0,"writeable":0,"value":{"CTD":"2017-02-10T11:17:35+00:00 Fr","CTR":"room","UMD":"clock","MMT":"20.0","CPM":"auto","CSP":"31","TOR":"off","TOD":"0","TOT":"17.0","TSP":"21.0","IHT":"20.80","IHS":"ok","DAS":"off","TAS":"off","HMD":"off","ARS":"init","FPA":"off","ESI":"off","BAI":"CH","BLE":"false","BBE":"false","BMR":"false","PMR":"false","RS":"off","DHW":"on","HED_EN":"false","HED_DEV":"false","FAH":"false","DOT":"false","HED_DB":""}}

Same problem here...Followed all the steps in https://www.domoticz.com/wiki/NefitEasy

but he pm2 logs remain empty... And also no data in Domoticz

2017-02-12 15:20:03.542 Error: NefitEasy: Error getting http data!


The script nefiteasyhttpserver.sh. No typo's...

#!/bin/bash
/usr/bin/easy-server --serial=xx --access-key=xx --password=xxx --host=127.0.0.1 >/dev/null

help is much appreciated!!!

Assume you did a chmod +x /usr/bin/easy-server and the same for your start-script??

Works like a charm here!

Unfortunately no connection again for more than a week now. Nothing changed in the configuration but in the log is see a lot of: Error: NefitEasy: Error getting http data!

Reboots did not solve the problem. Am I the only one with this sudden problem? The easy can be reached with to iPhone app so it doesn't seem a Easy connection problem.

Thanks

I get an http error now and then, but not often.

What version of Debian do you use? Seems the newest version (Buster) has issues with the nefit Easy HTTP server, due to SSL changes. Check here. And then paragraph on "Problems on recent Linux distributions".

Else: can you check the output of the server using the terminal?
