I’m using a gas meter from itron with an attached reed contact. I managed to install a device in ESPHome using the addon ESPHome Device Builder. The device is online, works fine in my WiFi… but when I add sensors in the yaml of the device and install it wirelessly the log shows me that it has been set up and works. However, HA does not take it over! The problem I encountered is that the api connection regularly show “Reading failed Connection_Closed errno=128”. I upload screenshot which shows the log. I suppose that this might be the reason why HA does not take on board these sensors when I look at the device (second screenshot). Any idea… Tested already network. But this is not the origin of the problem…By the way, I’m using HA as a VM on an unraid server…
What version of ESPHome addon are you running? Based on your HA version of 2025.4.2 I’m assuming your ESPHome version is similarly aged. There were some improvements that might be related to your issue that were in 2025.8. I’d update your ESPHome addon, clean build files, and then re-flash your device.
