Cannot connect to UGE600

[imihailovs]

I am trying to add UGE600 gateway via HACS installed component and I can't seem to connect to the gateway - tried both real and all-zero EUIDs.

I've made sure to maintain Local WIFI setting and I've also tried connecting via Ethernet and WIFI connections one after another - no success - I'm getting "Invalid IP address. Try again." error message.

Is there a log file somewhere that I can use to analyze the response from the GW?

[alex-ricobon]

same issue here, did you manage to fix it?

I have the same problem for the UGE600, but I got the error-message: "Unknown error occurred" In the log I find:

Seems to me as if this is a problem of the underlying pyit600 -library, https://github.com/jvitkauskas/pyit600

Edit: I tried with the underlying pyit600-library. With command: python main.py --host 192.168.xxx.xxx --euid 001E5E0909xxxxxx I got the same error.

But python main.py --host 192.168.xxx.xxx --euid 0000000000000000 works fine!

Hi All, I just purchased a Salus IT600 underfloor heating automatization, hoping to integrate it in Home Assistant, and I am at the point that I will send it back if not doable. I have downloaded latest of the integration from HACS and when I try to add IP and EUID the error of Failed to connect, please check IP address coms back. I have tried the troubleshooting from the readme, all looks good, but error persists. I am not an IT person, and not really understanding the above solution. Do you mind creating a tutorial as for a person without required IT knowledge? Thank you!

Hello. I have the same error. Also found in the HA logs the following:

Logger: pyit600 Source: custom_components/salus/config_flow.py:44 Integration: Salus iT600 (documentation, issues) First occurred: 00:47:29 (1 occurrences) Last logged: 00:47:29

Timeout while connecting to gateway:

Hi, I have simmilar issue,

But what I found also is that:

Also check if you have "Local Wifi Mode" enabled:

Open Smart Home app on your phone Sign in Double tap your Gateway to open info screen Press gear icon to enter configuration Scroll down a bit and check if "Disable Local WiFi Mode" is set to "No" Scroll all the way down and save settings Restart Gateway by unplugging/plugging USB power

In my gateway this mode was disabled

Trying this righ now - I will inform about results.

[palladin8282]

Hi All, After enabling the Local Wifi Mode to on and restarting the gateway I was able to establish connection :) Maybe this will help you too.

On my side my router has an option to isolate IoT devices and Salus Gateway was one of those isolated devices (and the and the HA server not), that's why Home Assistant was unable to connect. Solving this was fixed my issue

[imihailovs]

Came back to integrating the Gateway, but still facing the same issue. Both HA and Gateway are on the same subnet, firewall doesn't block anything. Local mode is enabled on the gateway. What I have noticed is that I can't ping the IP address of a gateway. Could be normal, don't know. Anyhow, the error I am getting from the logs is as follows:

`This error originated from a custom integration.

Wow thanks @stvogel using 0000000000000000 works! o.O

[bjorn-lebel]

Hi, i have the same issue as @imihailovs, The UG600 are connected and it works in the app, with equipment connected all through, that i can control through the app.

However I cant register the gateway with HA...

It looks like i am stuck in between, if I reset the gateway completely and connect to it in the offline mode I can access a webserver on the wifi side of the gateway (even if that webserver says 404...), so far it looks promising...

However if i instead connect the LAN, and it is registered to the internet, it goes into "darkmode" and dont respond to anything, either on the LAN side or on the wifi side with a configured SSID. I can see the IPs and MAC addresses on my firewall but the UG600 doesnt respond to anything!

I am leaning to that a firmware update closed the access when connected to the internet.

I have factory reset it like 20 times by now and whatever I do I come back to the same state, where Local WiFi Access are enabled but doesnt respond (in either working mode).

TBH and warn others, I will return it and buy another system!
