Integrating borrowed ECU-R with HA: Do I need inverters/EMA account?

[jvnrambo]

Hi there,

I'm testing the "APsystems ECU Reader" integration with my ECU-R 2160 (firmware V1.3.18) and I've run into an issue: I can't add the ECU to my Home Assistant monitoring.

The ECU is connected via Wi-Fi to my local network with a fixed IP address. I can successfully "ping" it and even execute the command APS1100160001END, receiving the expected response on line 4 as per the integration's website.

However, when I try to add the integration in Home Assistant using the ECU's IP, even after waiting more than 10 minutes, I get the message: "No ECU found at this IP-address or ECU is recovering from restart".

Currently, I don't have any microinverters installed, and consequently, there's no production data in the EMA App. I also haven't created an EMA account. I've only borrowed this ECU-R from a friend initially to see if I could integrate it with Home Assistant for monitoring purposes using your (HAEdwin- APsystems ECU Reader) integration. My main question is whether the absence of data or a registered EMA account could be causing this error.

Also, I have another question regarding future expansion. For controlling, sending energy, power on/off microinverter, and other more advanced functions, would it be better to purchase an ECU-R or an ECU-C (which has the advantage of Ethernet connectivity)? And for the ECU-C, should I try to get one from the 2162 series?

Any help or guidance would be greatly appreciated!
