Communicating to a Deca router

ESPHome
1

I have problem connecting ESP32 to my homeassistance. I use Homeassitance green.
I have several ESP home projekt that works fine. They all use a Asus router.
My next projekt is outdoors at a distance of 100m from my house.
For this projekt I want to use a DecoMesh X50-Outdoor Wifi router.
It is connected with cable, to the same switch as the Homeassistance green.
I can not get it to connect to my ESP32 unit.
At the moment the units are close to each outher, for test of communication.
If I look in “Fing” the adress for the Deco unit is: 192.168.1.132
If I look in the Deco app in my phone the adress is: 192.168.68.1
I use a fixed adress for the ESP to:192.168.68.51
This is part of my yaml file:
wifi:
ssid: gramek
password: xxx
manual_ip:
#Set this to the IP of the ESP
static_ip: 192.168.68.51
# Set this to the IP address of the router. Often ends with .1
gateway: 192.168.68.1
# The subnet of the network. 255.255.255.0 works for most home networks.
subnet: 255.255.255.0
I have also tried to set the IP for the router to 192.168.1.132
It is not working either.
I have set the yaml file to work with my Asus router. Then it works fine.
The ESP I use is with an external antenna.
I tested how far my Asus router could reach. It was about 75% of what I need.
It is located in the wrong side of my house.
The Deco is in a window that is in line of sight with were I want the ESP unit.
If it is to far I can move it to a closer house.
The problem is to get the Deco router to talk to my ESP unit.

This is your issue, you have two different networks (192.168.1.0 and 192.168.68.0) that don’t talk to each other. You need to set up your network so that you only have one DHCP. I don’t know the Deco but look for a setting in it that says “Access point” or similar.

Thank you very much. I found the setting. Now it works. I have just tested that I can reach 200m with external antenna on the ESP32. All is good.
