I have had a slimmelezer (https://www.zuidwijk.com) since August 2021 which has been working flawlessly, until 3rd May when it stopped communication.
I can update the ESP but only over the USB, and it connects to the WiFi when connected to the P1 port - this I have tested by setting a new local IP address in the yaml-config.
Log times out. OTA times out.
All sensors are Unavailable.
No updates to HA or ESPHome itself had been done.
This is my config file:

) you could contact the supplier for more specific device support to troubleshoot because I don’t have a ESP device.
