Have you read through the wiki here
The pin out of the connector: centre pin is Tx and the right (as per your picture above) is Rx
According to the hardware link in your post: White: TXD and Green: RXD
In other words, I think you have the white and green cables the wrong way around as you connect Tx to Rx and Rx to Tx.
Another thing to try, here on the wiki it says for your panel type you should set the baud rate to 38400. If that doesn’t work then try 9600.
Good luck
Sorry that my last post was lacking some information. Had a couple of hungry kids around
Here’s my interpretation of the link (attaching the wires): It says “white RX into USB port” and “green TX out of the USB port”, hence white should be connected to the TX and the green to RX. The last instruction of the link just tells us where to attach the wires. Correct me if I’m wrong.
The things I have some concerns with are: Baud rate
I have used 38400 so far and will test with 9600 as well. USB path
I have actually no idea which number (x) to use in the dev/ttyUSB(x). Do you know where I can find that out? Download code
I have tested 5650 and also another alphabetical code I found in the panel under Installation settings / Communication (which I believe to be wrong though). As I understand, this code is not critical to get the connection itself working initially(?) Step by step
Are there any recommendations for series of events that I must follow. For example; 1. Power off and disconnect battery from panel. 2. Connect the three wires. 3. Connect the USB to RPi. 4. Install integration in HA. 5. Restart HA server and connect battery+AC to the panel.
Can I see that the panel understand that it can connect to Home Assistant? When I disconnect power and battery and leave it for a while, it starts with saying that it is syncing with device. Is this just standard start up procedure or does it mean anything for the USB/TTL connection?
I’m assuming you have an HA installation using an instance of Supervisor.
I would start by trying either /dev/ttyUSB0 or /dev/ttyUSB1 as the interface. Also, certainly try a baud rate of 9600. Additionally, I agree with Dave; the wires look to be reversed based upon the product info.
Failing these things, check and see if the proper driver is loaded for your system. You should look in the Hosts log under Supervisor > System for something similar to this:
usb 1-3: cp210x converter now attached to ttyUSB0
If doesn’t show USBx, try what’s shown.
FYI, the chipset for your device is a PL2302 (vs the cp210x shown in my example).
As promised a few weeks ago I have created a new forum post/thread for this Integration.
You can find it here
As an aside, I have also posted a new release 0.6.9.0 to Github.
I am therefore closing this thread and will not respond to any further posts here.
Please post problems and comments in the new thread.
To everyone that has helped in the development of this Integration I thankyou very much. Most of the posts in this thread over the past few months have been installation problems or for minor bug fixes. I regard it as now being in a maintenance phase rather than development and as such have created a new thread so new users do not have to read 3 years of posts. Most (all?) of the relevant information from this 3 year thread is now contained in the wiki.
