Cannot reinstall the integration

[jurasjea]

Hi

I tried to reinstall the integration after several connection losses, but now I always receive the message: "No ECU found at this IP address or ECU is recovering from a restart."
The data is received correctly by the EMA application, and I have moved the ECU B closer to the inverters.
I really don't understand why I can no longer reinstall the integration, as it was working fine before.
Thanks
Jean

Reinstalling the integration does not solve anything. After a reboot of the ECU you have to give the ECU 10 minutes TLC to enable it to recover. After 10 minutes try to configure/re-connect. You might also think about other changes (like network changes) you have done in the past.

I tried several times reboot and waiting procedures before posting, and I checked the ECU IP address too.
May I have a hardware problem ? but the EMA application receives the data...

Hi, not to hijack this discussion but it is similar to my #27 that was closed.

I lost the data from the ECU and am getting the "No ECU found at this IP address or ECU is recovering from a restart." when I try to reconnect it. This is after moving the ECU closer to the inverters and updating the software. The EMA app is working fine with no interruptions but the HA integration won't show any updated data and has said everything is unavailable.

Yes, I saw your issue, and this seems to be the same problem. However, I already placed the ECU closer to the inverters without success.
I will try again, but I’m afraid of losing the Wi-Fi signal.
What is strange is that the integration was working fine for me before...

Question to @jurasjea and @kjroberts03
Is the ECU pingable from HA via both WiFi and/or LAN?

[kjroberts03]

Having a hard time pinging it, but I know it's connected via both wi-fi and LAN. Seems like maybe the wi-fi portion is what's dropping out and making it unrecoverable? But when I put the IP address of the LAN connection, it won't connect. The Wi-Fi IP address is fixed.

@kjroberts03
Pinging via LAN should not be a problem and should always work.
If pinging via WiFi gives issues, move your WiFi access point closer to the ECU.

[kjroberts03]

Ok it turns out I was doing it wrong. I'm learning this all as I go!

Pinged on both WF and LAN, and got replies from both. Can I set the ECU connection up to run via the ethernet cable rather than wifi?

[c0mplex1]

No, the connection between HA and ECU must run via a WiFi connection.

The LAN connection is intended to provide the APsystems servers with the data coming from the solar panels and is used for any software updates for the inverters and ECU.

Thing is that the integration (but also the ECUapp or EMA Manager app depends on port 8899 and this port is not available (opened) on the wired (ethernet) interface except for the ECU-C. For normal operation (without the integration) the ECU can operate either wired or wireless.

@jurasjea is the issue solved in the meanwhile?

Hi !
I had trouble connecting the integration to the ECU by reducing the distance between the ECU and the inverters. It started working again when I placed the ECU very close to the WiFi router and removed the WiFi antenna, while not having too many obstacles for the Zigbee signal. I will monitor in the next few days if the connection is stable, and try to find the optimal location to place my ECU.
