This sensor is already registered

I’m trying to register device 4522171 but get a “This sensor ID is already registered.” error message. Would you please release the ID?

@Jan_van_Bemmelen Please check that only one sensor per sensor type is registered. It’s not possible to register i.e. 2 SDS011 on one NodeMCU. This would lead to the same error message.
The chipID itself is not registered yet.
