Home Assistant and ESPHome Help - No Devices?

[missmah]

Hi all,

I have a new Home Assistant VM setup with ESPHome installed, and the meter installed with the YAML from: https://github.com/CircuitSetup/Expandable-6-Channel-ESP32-Energy-Meter/blob/master/Software/ESPHome/6chan_energy_meter_main_board.yaml with minor changes for my Wifi, and the new way of specifying:

esp32:
  board: nodemcu-32s
  framework:
    type: arduino

Nothing that should cause material issues, I think. I have firewall, DNS, NAT, etc. all setup to enable the device on my Wifi router to communicate with HomeAssistant. The network communication appears to be working fine (I can OTA upload new firmware, see live logging, from the NodeMCU-32s, etc.)

I'm currently powering the board over USB, don't have a 9V adapter plugged in yet, and no CTs connected yet. Still, it outputs a stream of text like this regularly via the log:

So, I was expecting to see some devices appear in Home Assistant, even if they're measuring 0V, 0A, etc. But, I don't see any devices/measurements in the Home Assistant dashboard. Is this simply a case of "it won't add any until there are actual CTs attached?"

Thanks in advance for any help/advice anyone can provide.

P.S. Here's the full startup verbose log before it starts looping over sensor readings:

I found my own answer:

First, I plugged in the 9V AC adapter and hooked up a single CT (to the AC adapter's wire.. which should cancel itself out and read almost 0W), but at least be hooked up...

Then you need to go to Configuration -> Devices & Services -> Integrations -> Add Integration

Then add the DNS name of your energy meter device.

After that, it added the integration and I can see the device on my dashboard:

I'm quite surprised that this isn't automatic...
