From what is supplied information wise, Acurite uses the 433 mHz frequency for their setup. I checked on how each frequency is different, and I think I see where the potential problem may be. The 433MHz is a commonly used frequency band for all types of equipment that require little power, such as garage door openers, headphones, baby phones and remote controls. Also many inexpensive transmitters and receivers for switching devices and light dimmers operate on the 433MHz band. Due to the absence of bidirectional communication and encryption, protocols are often of a simple nature. Because many different types of devices are permitted to use this frequency, it is more susceptible to interference. The development of the IoT probably is a contributor also (Internet of Things).

I believe in some review I read that AcuRite's instructions mention keeping the inside equipment away from other electronics.
I have seen in the AcuRite reviews of their previous products that folks seem to be good with what they got, and they had little to no problems with them, but it's seems the most latest releases seem to be less that great. Some of the issues are possible quality-control issues with whomever the weather companies contract with to produce their products (substandard chips / bad solder / bad design / bad QC / little or no instructions for the recipient of the station from the company). All the weather station brands will get some bad eggs in the carton.
My two-cents... now two dollars and twenty-two cents due to inflation. If I'm wrong, please let me know - I'm open to correction. If I wasn't allowed to put the webpage links of my info in also, please advise. Thanks!
