Have you had a cold snap or any sudden change of weather come thru recently, such as the night before they quit working? Are all of the outdoor sensors battery powered?
when our wireless stations sporadically stopped showing sensor signals,
we relocated the sensors/station. that worked until it did not.
(we have only two: LaCrosse and Oregon Scientific)
we reset everything and they worked until they quit.
bottom line: insects were getting inside the sensors.
apparently, some insects LIKE electricity.
“There are a variety of insects that have an affinity for electrical hardware…”
During the day today they all started picking up their signals again. Not all at once but over 12 hours or so.
I live in a rural area and no neighbors are too close. The hardware and batteries all look visually OK - no cracks, corrosion, bugs or water. Nothing new in the house. I have shut off individual breakers in the house but never all at once which is what I will try if this happens again.
This event started on Oct. 5 in the early AM EDT probably around 3:00 AM give or take an hour.
The event last year was on Sunday June 2 but I don't know the time. Here is a link that a friend sent me at the time that seemed like it could have been connected to.
I know nothing about the site but it was interesting to see what supposedly happened at the same time.
I don't know the MHz but will check into it.
One or two or even three having problems at once might happen but five unrelated ones at the same time points to something other than the weather stations themselves. It just tough finding it.
420-470MHz it’s ham radio band in USA.
433.00-435.00 are Auxiliary/repeater links
Also 400MHz band is used for home security monitoring radio links, taxi repeaters etc. Those stations are using high power and can disrupt communication between weather station base and sensors even in 10-20km range because of low quality RF section in those devices.
Since it is ISM band you can do nothing about that except moving to 900MHz.
