Hello,

i am using the http binding to control smart sockets flashed with esphome and a realtek RTL8710BN chip in it. (btw. this are Tecking SP22, if someone need the esphome config yaml pleas ask) Because the esphome framework does not now offer mqtt support for the realtek chip i am using http get and http post requests to control the smart plug.  
If i use the http binding an typ in the host name “esphome-socket14” for example i get the following error:  
[WARN] [p.internal.http.HttpResponseListener] - Requesting ‘[http://esphome-socket14/switch/relay\_1](http://esphome-socket14/switch/relay_1)’ (method=‘GET’, content=‘null’) failed: java.net.UnknownHostException: esphome-socket14: Name or service not known

If i am using the ip adress instead of “esphome-socket14” it works perfectly. What i am doing wrong??

Here is my configuration of the http binding:

It seems that java is not able to properly resolve the host-name to an IP address. Do you use a Linux-based system?

Thank you for your fast reply. I think i found the problem. I had to add .local to the host name and it is working now. Maybe this is because of the mDNS resolution.
