Only light entity becoming unavailable

ESPHome
1

Hard to find a good topic (short) for this one. I have an esp8266 controlling an IKEA ansluta light in my kitchen. The Light entity becomes unavailable suddenly and the only thing I’ve been able to do to get it back up and running has been to remove the integration and add it again (that is, this individual Device). Restarting the ESP (even power cycling) or home assitant does not do anything. All other entities under the same device work fine besides the light in Home Assistant. If I go to the web interface of the device the light works well there.

I take it everyone here finds this as strange as me. Why is only one entity from the same esp is becoming unavailable. Still at this… Restarting my router, ap, home assistant or the esp itself does not resolve it. The only way of getting it back up has so far been by removing the integration and adding it again. By that I mean only this particular esp, not every esphome related thing.

Edit: If I disable and then enable the device its also a fix.
