Slimmelezer+ losing connectivity every couple of days

After configuring the slimmelezer+ (https://www.zuidwijk.com/product/slimmelezer-plus/) using the ESPHome integration, everything works great and I could see my Energy & Gas consumption in my Energy dashboard of HASS.

The problem that I have is that the device becomes unavailable every couple of days, and no values are read anymore.
The only workaround for now is to unplug and replug the device into its P1 Port.

I am living in NL and I am currently using this device to read values from a Landis Gyr + SMR 5.0.

It became unavailable 3 times already in 1 month time. The first 2 time it was approx. 10 days after starting, while the last time was 4 days.

From HASS, it seems that it cannot connect anymore to the slimmelezer+ device, with the following warning displayed in the logs:

Logger: aioesphomeapi.reconnect_logic
Source: runner.py:128
First occurred: 09:18:33 (3 occurrences)
Last logged: 09:35:32

Can't connect to ESPHome API for slimmelezer @ 192.168.178.165: Error connecting to ('192.168.178.165', 6053): [Errno 113] Connect call failed ('192.168.178.165', 6053)

I am not sure whether this is a hardware problem, by the looks of it, last reported Wifi signal was -65dBm, which should be sufficient for the device to communicate over Wifi.

Any ideas or additional logs that I could use to troubleshoot the loss of connectivity?

Do you use external power. Or do you get power from the p1?
Maybe your meter has some issues. So you could try what happens with usb power.

Also if the issue persists. You could try to check if there is something in the serial log. I know it’s not ideal as you need some device reading the serial in your electrical closet.
But I would try usb power first. And yes, still it could be a hardware issue.

I have the same issue. Sometimes a restart of the Pi4 helped. In other occasions uncouple and reattach the slimmelezer helped. But more often than not, the slimmelezer remains not available to HA.

However, when I point my browser to the IP-address used by the Slimmelezer, I get all the data streamed right away. So it seems to be an issue of miscommunication between HA and Slimmelezer…

Are any solutions to this issue known?
