美国采购需求：电子产品，变压器，wifi变压器

I've encountered an issue with my unit. After it stopped working, I tried resetting the breaker, and now I see a blue WiFi light. However, neither of the switches seems to be functioning. I've attempted to long-press the switches to reconnect, but there has been no response. Despite having power to the unit, I'm unable to operate the switches manually or get it back online with WiFi. I'm looking for guidance on troubleshooting or potential solutions to get the unit working again. Any help would be appreciated!
