Forced to new Smartthings app from classic by dead phone, roughly simultaneous with the forced Samsung account change. Not sure the whole sequence but between phone replacement and login change I couldn’t connect to anything.
Factory reset hub and reconnected to new Smartthings app not classic.
Have “GEN 1” Spruce Irrigation controller. Could get it to ‘drop’ old connection (Fn-16 on front panel) and put itself up for pairing (Fn-9 on panel). Shows up in new ST apps as a VALVE. A 16-zone smart irrigation controller with rain sensor and soil sensors, and it shows as an effing VALVE.
No way I can find to install the ‘smart app’ that used to be present in the old ST app for this device. I know Spruce has also moved on past ST with a new Wifi “GEN 2” that doesn’t require a hub at all. Maybe I should follow their example?
Seriously this is the most borked “upgrade” I’ve ever experienced in my life.
