rtl_433 spends a lot of time whenever it hops from 433mhz to 915mz adjusting the minimum detection level based on noise (automatically). I purchased a fine offset clone WH25 today which is on 433mhz to avoid this problem. Perhaps what is happening is a lot of the archived results are getting nulls because the slower (WH32B) is not done communicating by the end of the archive_interval. Note the short archive_interval = 30 or 120 seconds. Is this way too short especially in my case?
