Unable to get AG8 board to function - Smith6612 - 02-16-2025
Hello there!
I have recently purchased two AG8 Smart Controllers, and I am having trouble with both of the boards.
I am trying to use the boards with the ESPHome firmware, and have built demo firmware inside of ESPHome using the ESPHome YAML file found here: https://www.kincony.com/forum/showthread.php?tid=5889 . I am able to enter Download Mode, and successfully flash the firmware to the device. However, after power cycling the device to boot the firmware, I cannot get any network connectivity to the device. In my YAML config, Ethernet is selected. The device establishes an Ethernet link but does not send any traffic (No DHCP/No IP Address obtained). I have also tried to switch the YAML config to use Wi-Fi, with Wi-Fi Hotspot Fallback, and the device never broadcasts in AP mode.
I am also unable to connect to the ESP32 using USB Serial in normal boot mode. Only if I boot the device into Download Mode, in which case the device appears and I can send firmware to it.
I have also attempted to install the Tasmota firmware. The Tasmota firmware was outputting on serial, but all I could see in the serial output is the device boot looping, attempting to load the firmware.
I am wondering if this has to do with the power supply for the board. I am currently using a 9V 500ma power supply. According to my Multimeter, the power supply at the terminals while the board is active reads 10.6v. The product page says 9V-24V is the power input range. Is my power supply acceptable or is there a recommended voltage/amperage for the product? I do have other ESP32 powered devices at home which operate on 5V 1A power supplies without issue.

i suggest to use KCS v3 firmware for AG8 contrlller. it's very easy for home assistant. next week will make video tour about AG8.

Hello!
I forgot to mention in my original post - I also tried the KCSv3 firmware for the AG8. The device behaves the same. I do not see the Wi-Fi Hotspot broadcast, and the device is not connecting to the network (although the Ethernet port has a link/flashing orange light).
To confirm, I have flashed with these settings.
Hello again!
Just wanted to reply back. I was able to locate a stronger power supply, and my product is now working. It appears the other power supply, while it is capable of powering up the ESP32-S3 to Flash, is not powerful enough to run the board in normal boot mode. I located a 12V 1200mA supply, and the product booted up.
I have attached photos of my old supply and new supply, as well as the voltages on the output without load, and with load, on the stronger supply.
Thank you!

ok, good, DC 12V 1A is ok.
