I have succesfully used a cheap tuya meter from aliexpress (white box with two clamps and two wires for voltage). With the official tuya integration you can monitor one device (or whole hose) but if you are willing to jump through some hoops and using local tuya you can get both measurements separetly. I also have a cheap aliexpress DIN style tuya smart breaker that works fine with tuya integration. And finally I have used a tplink kasa smart plug hs110 for 240V measuring (it is advertised for 120V in north america and it has 120V outlet. All of this in 240Vac 60Hz.

Accuracy for monitoring purposes is fine.

Is this your first time unlocking/flashing a device? If it is, I would recommend first looking into installing the android adb tools, sometimes you can find minimal installs, then turning your phone in boot mode and trying to comunicate with it. This is usually done with the terminal and after you send a specific command the phone should reply with its identifier (i dont remember the specifics). Once you can communicate with the device this means the drivers you need are installed properly and you should be able to see your phone in the xiaomi application (or unlock the bootloader directly from the terminal).

All of this assumes you got the unlock code from the xiaomi site (which ofently does not work) but there are some shady programs around to bypass this step.

Did you also installed the drivers? It took me some time to learn that your computer may see the phone in regular mode (accessing content) but not when you turn it on recovery mode / boot mode and this requires additional drivers.

I dont love the gazillion batteries my lock uses… but it’s been around a year since it was installed and it has about 50% battery left. I don’t have it connected to the internet. I love replacing AAs and AAAs for rechargable lipos but I KNOW my wife won’t approve, haha.

As a mexican I see this as pure propaganda. But I do hope it works because it has the potential to be a very hackable… thing.
