Can't wait to get back home from holiday home to get experimenting with all this stuff. Thanks for creating the group. Paul gi4fzd

I've been using Node Red for several years.? It's been fantastic to allow me to do various automation functions around the house without knowing how to code. I have some extra input/output PC boards

Bret While you are waiting for Dave to help, it appears your W2 serial connection is working, because the backgrounds have changed color. However, the W2 is not updating the data because it is locked

Bret; You are close. Looks like the W2 is talking nice with the Raspberry Pi / Node-Red. I will turn this over to Dave now to get you going Dave - I received the same error message. For me, installing

If you click on the error it should highlight the node where the error is located. Cannot reas subsrt of undefined sounds like the node is not receiving data. Bret, i’m hitting the bed. Call me

Hi Alan and thanks for the above that is what I have been doing and I am connected it looks like, I get this error in Debug mode 7/18/2020, 9:38:12 PMnode: C44|client bind Client_id

Bret - This is what worked for me: Step one - Use the Serial Request Node. Remove Serial out node, wire inputs to Serial Request Node out. Same for "in". [image: Screen Shot 2020-07-18 at 10.00.01

Bret, try to select by ID as I have shown in my previous email. Also on the command line run this wile plugging the USB device in and out to see which ones come and go: watch ls /dev/serial/by-id/

That is the same Cable as I am using, and the latest Flow from Daves Group.io I have several COM ports listed not after playing around with the WN2 Watt Meter and making sure the FTDI driver worked

Ok. I have no serial devices. 73 Dave wo2x Sent from my waxed string and tin cans.

Yes. I have it auto ranging plus ability to select range of bar graph manually. The numeric readout is always auto range. You can also select auto scan, sensor 1 or sensor 2. The button background

I no longer use the serial to TCP converter. If I were I would use the TCP in and out nodes. I am now hard wired from the W2 to the Pi as described above Using Elecraft serial to USB FTDI cable. The

Dave, I use auto range and and sensor scan in my code. That way I don't have to worry about which sensor is active at the time. 73, Andreas, N6NU

My experience is that it is best to specify the serial port by ID This is especially helpful when using more than one serial adapter or multi serial adapter on the same Pi. It will protect your setup

Works for me using serial to USB FTDI cable.

Resending Bret. Use these settings. Instead of the TCP in and TCP out nodes, use the TCP Request Node. It has an input and an output, just substitute for the TCP in and the TCP out. Here is a

Actually I believe he will want to use serial on and out. I do not believe I have seen a serial request node. He is not using a serial to IP adapter. Baud rate should be 9600,8n,1 Dave wo2x Sent from

I’ll be available tomorrow and Alan has added a few tweaks to the W2 flow. Give me a call in the morning. I will be up since two hours ahead of you Once I verify Alan’s changes on Bret’s W2 I

You say the usb cable shows as connected. Good Linux found the USB port. Use the same USB port with the settings I sent you, and use the TCP Request node instead of the two TCP in and TCP out nodes.

Yep tried that I am now testing on the bench using the Windows App and all work A-OK, Just wondering do I have to set the COM port serial number in Linux anywhere? also what baud rate does the W2
