I installed this node for my new GREE airco's and it works very well. My problem is that I cannot give this AC a fixed IP address by DHCP reservation, so now I was wondering if I can dynamically change the ip address of the GREE node. By means of the ARP node I can determine the IP address on base…

Finally I have a solution to the problem. @Trying_to_learn I have done what you already suggested, I put my own router behind the router of the ISP. My ISP gave me a another modem/router that was able to function in bridge-mode, so it delivers a public IP address to my own router. Now I can do whate…

Not a solution, but may be helpful. [image] Dynamic IP address in node TCP in & out? General Stephen, you are totally right, it works also for the port number. I'm not sure what I did wrong last time, but this is ok now. Thanks for testing and correcting my false state…

thanks @Trying_to_learn , I already tried this in several ways, but nothing seems to work so far.

Why can't you give the A/C unit a fixed IP address? Who is doing the DHCP? Should be easy enough to do. And sorry if the link seemed like a hand off..... I am not running on all cylinders just now but I remembered that thread and suggested it.

@Trying_to_learn , My modem-router can only be reached and configured by means of website of my internet-provider. The most I can do there is port forwarding, that's about it. So no IP or DHCP reservation possible. The AC units can also not be given a fixed ip address, as far as I know.

That's a shame. (About the modem-router). I don't understand why that is the situation, but I'm not going to stress on that. Could you put a router in between the A/C and the existing router? I know it is more work and introducing NAT (well, you could get around it, but that is complicated) and …

@Trying_to_learn , Thanks, same here. I already thought about my own router or even switch to another internet provider, where I can control the router myself, but both solution are giving me many more problems and headaches.

So where on the network are you and the A/C? Just it seems weird the whole set up. Ok, the "router" is some how under the control of the ISP (provider). Thought: [Screenshot from 2022-06-28 22-42-32] (I'm not an artist) The top is what is.... You can't control the IP allocation. But if you…

@Trying_to_learn , Like I said, I considered that already, but in my case that would introduce new problems for me, so I ruled out that option.

Yeah, sorry. I just now noticed you did say that. I think it is time for me to go to bed today. :wink: It is 23:12 local here and it's been a long day.
