Hello.
I just noticed in the Pi-hole logs several DNS requests (6 every 30 seconds) to eu-api.coolkit.cc which, according to a quick search, corresponds to Ewelink (I do have the Ewelink module on Gladys).
Nothing serious, but it might be possible to reduce the number if that’s the case? 
I’m tagging @Pti_Nico who is the developer of this service
Yes, this is to retrieve the status of the devices.
We can reduce it, but it will take longer to update…
Ok, that seems normal indeed! I was just making sure it was intended behavior
