Help me sync my dimmer light switches (Shelly in wall dimmer)

Hello everyone. I am in the USA and have a few shelly in wall dimmer switches. I have several 3 way switches and most of them work using a script provided to me from Shelly. however every once in a while, the don’t work and the script stops which means I have to log into the web UI and turn it back on.

I can control the switches with HA and I am looking to create an automation that will match the settings from one dimmer to the other. So if the dimmer level changes, I would like it to sync to the other switch. One switch is wired to the load the other is just wired into power and has no direct connection to the circuit. It must control the dimmer that is hooked to the load. I used a blue print, but it only sync the on/off state if I control the switch from HA not the physical switch.

I set up Link On/Off State of Multiple Devices v1.0.0 blue print from
