Homey Energy Dongle has lost connection - instable connection

My Homey Energy Dongle loses connection and reconnects often. I have this since the beginning, but starts after a couple of days or hours or so after I reset it.

Its not my WIFI as I tested it even with another AP.

Anyone else has the same issue and maybe a fix for this?

What does that even mean?
Like, the dongle is functioning perfectly well when it’s connected to the another AP?
In that case it’s not the dongle.

The opposite, the dongle loses connection in both situations. I used different APs. I now use 2 Unifi Pro APs managed by a controller and monitored 24/7, where other devices have stable connections for months.

The dongle is connected to its own power supply and in the P2 port of my meter. The AP is like 30cm away.

Other devices have stable connections. The dongle does not. Loses connection from time to time and restores it hours later or I need to restart it.

Is it a WiFi 7 AP? I heard that those have issues with some IoT devices. In my case, my Zyxel Nebula WiFi 7 AP is also causing issues for one of my ESP8266 modules, showing constant disconnects with “STA Timeout” as the disconnect reason. But I’ve also read about similar issues with UniFi WiFi 7 APs/

What does it show as the “Disconnect reason” in your network? Is that available in Unifi?

I just checked in the controller and the Dongle is connected, using WiFi-4 (2.4GHz). It uses a 2.4GHz connection. The AP has both 2.4 and 5 GHz available. WiFi-5 is also available via the 5 GHz connection, but it seems it does not use that.

Ok, I found an option in the controller of the AP’s (WiFi Doctor :)) It has an option to opzimize for IoT and other connectivity stuff. I will try that and see how it goes from there.

In the logs it does not provide a specific reason. It just says that the dongle disconnected. Is there a way to see logs on this in Homey as it only tells in the timeline “Homey Energy Dongle has lost connetion”, but you cannot see any further details in there.

Hi SKO,

Radio signals weakens when distance increases, but same goes for very short distances. To make sure 30cm is not too close, you can temporary move the AP and see if things improve.

wifi-5 offers both 2.4GHz and 5GHz simultaneously; The wifi implementation of Homey products seem to struggle with that.

What might do the trick is to create a separate 2.4GHz SSID, and have the dongle connect to it.

I actually have that in place for other IoT devices, but not using it for the Homey Energy Dongle, will try that. Good suggestion, thank you!
