VenosOS and Autoterm Planar Diesel Heater

[devshack]

Hi,

i am currently trying Diesel Heater from Autoterm to integrating in VenusOS (Node-Red).

I have two problems:

• the transmission of signals is not reliable.
• Commands to only start the heater, leave to crash VenusOS. Other Commands not.

Under other Raspberry Distrubitionen are have no problems.

In the 99-usb-serial.rules file, fix the usb-port from heater.

# Autoterm Planar USB/serial adapters
ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="ABSCDHT6", SYMLINK+="ttyUSB_autoterm", OWNER="root", GROUP="dialout"

Testfile Node-Red:
Autoterm Test VenusOS.json

Do any of you have the autoterm in operation with VenusOS?

System: Venus OS 3.52 testing an 3.4.x
Raspberry Pi 4B 8GB
Node-Red Logfile have no track Error

Best regards

Hi, did you have any joy with this ? I am trying to do the same… Thanks

Unfortunately no, the last time it didn’t work at all

Got it working today after a lot of back and forth.

I will test it further over the next few days and see which setting was the right one in the end.

Great to hear you got it working. Please can you share your findings once fully tested ?

1.) cable from VAN PI USB JST (für Autoterm) – Pekaway

2.) Edit Files serial-starter.rules and create 99-usb-serial.rules

Step 1 - On Windows go to PowerShell and connect to raspberry (ssh)
Step 2 - Show all adapters with “ls -l /dev/serial/by-id”
Step 3 - Show Serial from the right adapter “udevadm info --attribute-walk -n /dev/ttyUSB0 |grep serial”
Step 4 - Show idProduct from the right adapter “udevadm info --attribute-walk -n /dev/ttyUSB0 |grep idProduct”
Step 5 - Show idVendor from the right adapter “udevadm info --attribute-walk -n /dev/ttyUSB0 |grep idVendor”
Step 6 - Edit the Files

/etc/udev/rules.d/99-usb-serial.rules

# Autoterm Planar USB/serial adapters
ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="ABSCDHT6", SYMLINK+="ttyUSB_autoterm", OWNER="root", GROUP="dialout"


/etc/udev/rules.d/serial-starter.rules

# Autoterm Planar USB/serial adapters
ACTION=="add", SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", ATTRS{serial}=="ABSCDHT6", SYMLINK+="ttyUSB_autoterm", OWNER="root", GROUP="dialout"
ACTION=="add", ENV{ID_BUS}=="usb", ENV{ID_VENDOR_ID}=="0403", ENV{ID_MODEL_ID}=="6001", ENV{VE_SERVICE}="autoherm"

Step 7 - Reboot
Step 8 - Check the Settings in PowerShell “ls -l /dev/ttyUSB_autoterm”
! Note: after a update are lost the edit and the new File.

Could this flow be imported into HAOS?

[devshack]

No idea, best to try it yourself and give feedback on whether it worked.

I have already tested it, and it works perfectly using a USB TTL RS232.
I am changing the dashboard nodes to use native HAOS cards, and except for the input_number sliders, everything is responding perfectly.
