I installed the smartlight usb dongle into one of my new Bosch 5000 mini split wall units and I got it working great. As soon as I installed a second one into another identical Bosch unit, I got just a couple seconds of operation, then both units displayed two dashes and stopped working.
What’s going on here? Can I have all 4 of my units working independently with HomeAssistant?
Hard to know from your description, because there is very little info about configuration of them.
Do they have different IPs mDNS names and so on??
They are each on my network with their own DHCP-reserved IP addresses. They look OK in the HomeAssistant dashboard.
OK, solved. The problem was I had one of the mini splits set to heat, and one to cool. Obviously can’t do both at the same time, so the system paused itself. Once all units set to same mode, worked OK. Nothing to do with configuration.
