What still needs checking
The ready-to-use product description conflicts with assembly wording in the store FAQ and guide landing page. The current offer is recorded as assembled.
Product copy advertises compass and temperature sensing; the linked drawing identifies the motion sensor but no separate compass. Exact sensor implementation remains unresolved.
