I have a number of smart bulbs, some Smart plugs and some Smart switches installed at home all controlled through the Tapo app. 
 

I'm about to upgrade my router and wondered if theres a way to change the wifi network in the tapo app, or do I need to delete all my devices and re-pair them and set up automation/groups from scratch 🫣

ive had a look but cant see any bulk/global settings in the app? 
 

thanks
