Communication with ATM90E32 failed Error

[haas844]

Hi,

I recently tried setting up the 6ch main board (v1.4, rev1) to work with Homeassistant through ESPHome, and keep getting the following error for both cs_pin: 4 and cs_pin: 5:

[E][atm90e32:132]: Communication with ATM90E32 failed!

I am currently using the Jameco 157041 power supply, with a HiLetgo ESP-WROOM-32 board (https://www.amazon.com/gp/product/B0718T232Z).

When I check the logs, I get regular updates on the WiFi status and nothing for the CT sensors. Homeassistant currently shows all the sensors as 'Unknown'.

I"m sorry the meter is giving you issues. Everything looks okay in the logs.

Can you confirm that the ESP32 is being powered by the meter?

Hi,

I believe it was an issue with the ESP32 I was using, I switched to the following board and everything started working as it should:

Thanks!
