Same problem for the last few days, impossible to connect the Roidmi app to the robot. Sending an email to receive the connection code is impossible (error message: sending failed). The https://www.roidmi.com website is no longer working either!

Can confirm the error with the Roidmi app. I didn't use mine for quite a while due to the conversion and then checked it.

After several attempts to reconnect the devices, this still failed.

They are now working again, but I use the Xiaomi app for this. Simply add the devices manually as a robot hoover and select the Roidmi Eve model. Reset the Wi-Fi with the centre and right buttons on the vacuum cleaner. Both devices are now recognised and working again.

Hope this helps.

I am reassured to hear that I am not the only one with this problem. The battery was flat after 4 years, so I put in a new one. As I couldn't connect the robot, I reset it and reloaded the app. I have the same problem as you. I hope they solve the problem soon. In the meantime I will test the Xiaomi Home app to see if it works
