Yeah, right! 😉
I don't have any reason to disbelieve him. He is installing many such systems a day, each different one requiring space in his phone. Once he has finished configuring and testing the heating system, he has no reason to keep it. The company, on the other hand, has remote access, for the purpose of continuously monitoring the system, and warning me when an intervention is necessary (which would be free of charge). The end result is a maintenance visit every two years, instead of every year. The furnace section needs changing a rubber casket periodically. It is a hot water house heating system called "condensing" type. The combustion is regulated so that the hot gases after the heat exchange is almost cold gases, and when they go out of the house they go down, not up as steam would normally do. It also generates liquid water. Meaning the efficiency is much higher. This can be done when the fuel is very clean gas, because if not the exhaust is acidic and corrosive (<https://en.wikipedia.org/wiki/Condensing_boiler>).
I do not understand why the device would care about the SSID being the same on two bands. Perhaps the phone app sees it is on 5 GHZ and doesn't trust that the 2.4 will works or has the same credentials, as the app doesn't see the 2.4 network.
That doesn't make sense. The phone will connect to whatever signal it sees and there is provision for going with the strongest signal. As I mentioned, both bands are on the same subnet with my network and there's no reason why they shouldn't be.
I know. But for the purpose of setting up, the app assumes it has to tell the device, via bluetooth, what are the ssid and password of the AP it has to connect to. It can not tell it to connect on 5GHz. It has to assume that the 2.4 GHz ssid will be there, without seeing it. It is designed to tell "connect to the same ssid as me" over BT.
I have seen recently routers advert they come with openwrt installed.
Mine was just an access point. My router is pfSense running on a mini PC. It's been many years since I've used a router from D-Link, etc. I prefer to keep the functions separate.
