I bought this smart plug: https://www.amazon.co.uk/SmartThings-Remote-Control-Scheduling-Monitoring/dp/B07TK4CC42 as recommended here: community.home-assistant. io/t/recommendations-zigbee-smart-plug-uk-w-energy-monitoring/430013/21
I want to configure it with ConBee2 connected to my HA at home but as far as I can see it need integration configured first: https://www.home-assistant.io/integrations/smartthings/#platforms it looks like it either need a HA cloud subscription or HA exposed to the internet which is a joke. Am I right or I misread something (I am new in a HA world)?
You are misreading, this smart plug is Zigbee and supported by at least Zigbee2MQTT and perhaps even ZHA.
Edit: Not ZHA apparently, but none the least Deconz.
