Pimatic Homeduino Problem

---

Hey , i become the Error:

[pimatic]: A uncaught exception occurred: TypeError: Cannot read property ‘length’ of undefined
at Function.Buffer.concat (buffer.js:289:24)
at afterRead (/home/pi/pimatic-app/node_modules/pimatic-homeduino/node_modules/homeduino/node_modules/serialport/serialport.js:369:36)

This is most probably a bug in pimatic or in a module, please report it!

Where is the Problem.
I use a Arduino Nano which is plugged in over USB in a Raspberry Pi 2. I follow the Installation Instructions from the ReadMe Site from the Homeduino Plugin.

cleared browser cache already?

Yes, but the Problem is still there.

No one has an idea?

Unstable serial connection. Replace either your arduino or power cable(s).

Ok, i will check this.

Hello, i have change the Power Supply to a 5V anderen 3A. The USB Cabel from the Raspberry to the Arduino have i changed and the Arduino.
But the Problem is still there.

I don’t know where the Problem is…

Tomorrow i want to Install the System new.

Have anyone a other Idea?

Hmm. What is the output of this command:
sudo node -v

sudo node -v
v4.6.2

Strange… Ok maybe Overkill but already installed a fresh raspbian?

Idk its a long shot but could you post your full config.json content?
Please use “```” before and after to post as code withoit the " ofc.

Hello, today I have installed the system a second time again. So far, the problem has not yet reappeared. I will test it now for a few days. I report if the Problem appear new.

1 week later and the problem is solved.
But now i have another question. I have buy this module: https://www.amazon.de/Neuftech-Wireless-Module-Transceiver-externen/dp/B01CI01F94/ref=sr_1_1?ie=UTF8&qid=1495054463&sr=8-1&keywords=cc1101
I have try to use this, but I can not control it.
Have anyone Experience or is this not possible to control this module with homeduino?

With Regards, Phil Reis

Nice to hear that the initial issue has been solved. Well the receiver you bought will not work unless you are building a cul stick with an Arduino and you maybe need other software for receiving and so on.

Better check our hardware tip and go for a 3400RF kit. That’s the rxb6 receiver and a transmitter. The transmitters are of no problem. There you can use almost any. But at the quality of the receivers there are big differences.
