Remote operating and Node Red

For antenna control, I started with Rotation Control for my 2M and 70CM antennas.  There are switches mounted on each antenna allowing selection for Right-Hand or Left-Hand rotation.   Energizing the switch coil on each antenna switches the antennas from RH to LH rotation.

I am using this USB Board:

https://www.amazon.com/gp/product/B07DYNVB38/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

I added this Palette to Node-Red to control the board:

https://flows.nodered.org/node/node-red-contrib-usb-hid-relay

I downloaded this flow from the Node-Red library for a toggle switch that changes state and color when pushed:

https://flows.nodered.org/flow/7325d06be6c8a415c877a941172dbc86

The first button will operate relay #1 and will “ARM” the other two polarization /rotation relays.  This will turn on/off 12 VDC to both the 2M and 70M polarization relay circuits.  I want to add a timer on the Flow to remove power from the relays if not in use for ???? amount of time.  That way I will not forget to remove power from the antenna relays when not searching for Satellites.

The second button will toggle between Right-Hand and Left-Hand Rotation for both the 2M and 70cm antennas.  The single  "Polorizaion" button operates relay #2 and #3, one USB relay for each antenna polarization switch.

Help — I want to add an interlock to not allow switching polarization if the Flex is in TX.  Can anyone help me get started with the front end part to import the Flex TX status into Node-Red?  I think N2WQ had the same kind of request..

Here is a screen shot of the flow:

Here is a screen shot of the Dashboard.  Pressing "ARM" toggles relay #1 on/off and will be in series with Relay #2 and #3 on the 12 VDC power.  Toggling the bottom button toggles relays #2 and @3 to change antenna polarization from RH to LH.  The buttons change color and text with each push/state change:

In addition, the Dashboard looks great on my iPhone.  I used the App Maker in Safari to add an icon to my iPhone home screen.

I will end here with a copy of the flow to follow.  I do not have knowledge of how or where to post flows for community use   (help).  Also, could not find how to just upload the text as a file.
