Rebuilding my Home Automation RPi3B+ with latest version of RPi, NodeRed and MQTT. I had exported the FLOW from the old system. After installing the new software versions and trying to import the FLOW I realized there is a little more to it than that. I had to install several nodes from the library…

DynamicDave is the winner. It wasn't the little blue dots he was concerned about, it was the lack of green in the button at the right end of the debug node. When I clicked in there everything came to life. I just couldn't get that idea out of my head so I investigated that node and that was it. …

[image] merkelck: my RPi is connected to the network via eth and I have wondered if I even need to provide wifi credentials to the RPi? If it is connected via ethernet then you can ignore wifi. Be careful though, if you configure wifi too then the pi will probably have two different ip addre…

[image] merkelck: my new router (an eero pro7) provided by my ISP. ... my RPi is connected to the network via eth Your ISP provided a £300 router? Who are they? I think the eero needs to be connected to an external ADSL/cable/etc modem, so presumably one of it's two ethernet ports is occup…

@jbudd has a good point. Can you ping the new pi from the old one?

Apologize for my confusion. Thank you for the link.

I am getting ready to rebuild again but here are answers to the latest questions. I can ping the new RPi from the old RPi. The 2nd port of the router goes to a 2.5G switch which goes to a 12port 1G switch and then all over the house. The two pi devices are plugged into that switch. The link to the…

[image] merkelck: The two pi devices are plugged into [a 12port 1G] switch. I strayed away from the real issue a bit by wondering about network topology, but it's good to know both Pies are connected the same. Barring confusion between devices, we do see attempts to connect to Mosquitto, so …

Sorry but the machine had already been shutdown. For "jbudd" , I have run those tests before several times as they are part of the course where this came from. They are run twice, for each method, with or without credentials and they both passed each time. And this also involved the change in the "a…

Concerning the switch; has the Mosquitto broker: user name and password been set to match on the switch? What about the rest of the switch's configuration? Reference: Setting up the Tasmota MQTT Switch (Sonoff)

[image] merkelck: And, Yes, your home network is identical to mine Umm Your network is identical to @dynamicdave 's with the possibly insignificant difference that your Pies are connected by ethernet and he shows his as wifi. [image] merkelck: At this point my procedures are exact duplica…

As I asked please post the flow inline, I get access denied on the link you posted, but that is not the preferred way to post flows.

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)

``` 
   code goes here 
```

See this post for more details - How to share code or flow json
