Today Iḿ using a Yamaha AVR as power amp for my Ultra and switching the amp on/off with Home Assistant and a wall socket. It works very good, but the amp use a lot of energy and have seven useless power stages. There is also a communication delay, so the sub is already on when the Yamaha goes on.
Iḿ thinking of buying a Fosi Audio ZA3 because it has an trigger input. Does the on/off function in Fosi ZA3 work with Wiim Ultra?
Or should I buy 2 of them, or anything else that works with Ultra. I want to use the trigger function and I understand there is a current limitation in Ultra HW.
