With the help of the support person I resolved why my EV Charger was not showing up on the Web interface. It was my fault because I had used two different email accounts for logins. It it now resolved.
The only thing remaining is why my solar output cannot control my EV Charger. I have a rate situation that I want to use the available solar in the morning and early afternoon to charge my EVs. I specifically purchased the EV Charger for that capability. I already have a Tesla Wall Connector and can manually adjust the charging rate on my phone if I wanted to monitor solar production every fifteen minutes.
