👋 Hi fren, welcome to the Combinder testnet! Please find answers to the most common questions below.
During the first stage of testnet we solely support a smart plug device called “Shelly Plus Plug S”. !!! The 'Plus' is a must!!!
It’s an amazing device that allows you to remotely switch on/off electrical devices and even more amazingly can measure the electricity that flows through it. ****Regional versions that are compatible end on: ‘IT’, ‘US’ or ‘UK’). If you have the choice we recommend to use ‘Gen3’ of the plug. Gen2 works as well, but it collects less data.
Here some pictures of how they look in different parts of the world.

In case you already own one of these, great, you can directly start using Combinder. If not, you can purchase one at following sources.
