My Kasa, Hue and Google devices can all get out to the world and I can control things from my phone without being on the wifi. 

All these are typical IoT which establish only an outgoing connection to the Internet where certain reverse or tunnel methods are used from where the App resp the cloud infrastructure the App does talk to can reach the IoT devices on your network.

Perhpas one mysetery we can solve while I find out more about the Smfy gear is why I can not detect the open ports using ay online tools. According to the settings, I have them open. See picture. I have tried with UPnP on and off.  

Agree, lot of mystery, paired with some odd support feedback by these vendors. Probably French to English translation issues (kidding).

The ports shown are forwarded manually to the Somfy controller one might guess. but as we both suspect, there is no incoming connection required - this would break users located behind double NAT, where ISP deploy carrier grade NAT (again leading to double NAT), and last but not least exposing these "thin" controllers to the wild Internet. thus very unlikely, as you already figured out, too.

Some smart design might allow certain connection-less access direct from the App on the local (W)LAN to avoid the loop over the cloud - wound be hard if you can't open the shutters in the morning or in case of a strom while the Internet is down.

WHen you say PRIMARY NETWORK, what do you mean? Wifi 1? 

Yes. As far as I understand the UPnP PMA works only on that WiFi 1 - can't think this should be required. Convinced BruceGuo can support my confused old brain please.
