Two ESPEASY nodes on same WLAN

[5rm]

I have one espeasy node running on my WLAN with IP 10.0.0.3, Gateway 10.0.0.2, without any problem.
But adding another node has not succeeded yet. ESP-0 AP appears OK and it can be connected at IP 192.168.4.1, but somehow configuring the new node is not possible. It looks like like the the existing and new node have some IP address conflict and talking on each other. DHCP server is on in my LAN router. Is it possible that all ESP units have the same MAC-address?
What is the right procedure to add a node to an existing setup? Can the LAN 10.0.0.* cause the problem?

Hi 5rm,

a MAC address is a unique number, try a fixed IP adres on your ESP module.
Try to setup the second ESP module after power powering down the first one.

Hi Andreo,

Yes I forgot to power down the first unit and therefore the second unit got somehow mixed up and finally loosed the AP ESP-0.
I then installed ESPEASY on a new NodeMcu unit and got it work OK with a fixed IP. So now I have two nodes sending data to my Domoticz server running on a RasPI.
