I configured the first one (called Roses 1) and it works perfectly.

I configured the second one (called Office Pot Plant) and it went through the configuration fine but then doesn't appear in my app in the Sensors section (Roses 1 appears, but Office Pot Plant doesn't). 

I tried to configure it again and it told me that the name Office Pot Plant was already taken, but it doesnt show anywhere.

I tried a factory reset on the Whisperer which worked but when I tried to configure it, it gave me the error "ERROR: Sensor XXXX already in your account".  

I've looked at my account on the web and it only shows Roses 1.

So I can't add the device because it says it's there already, and I can't delete it because it doesn't appear!

Please can anyone you help? I wrote to Support yesterday (from the email for this account) but I'm hoping someone has a DIY fix for this?

Thank you so much!
