5N1 won't stay connected to Smart HUB

  • Updated 6 days ago
I have a 3 year old 5N1 along with a new (01/18) SmartHUB after upgrading from the internet bridge. The wind speed stopped working on the 5N1several weeks ago but wind direction worked. I moved the 5N1 to be within 75' of the SmartHUB. Line of sight, nothing but a window pane between the 2. Today I took the 5N1 down from the post, took it into my workshop & cleaned the inside of all of the spiders & bugs (hoping to fix the windspeed), installed fresh Duracell batteries, and put the 5N1 back out on the pole. I used the SmartHUB IP address to look at it using a browser as I usually do, and the wireless signal strength was 0. It was working otherwise & I was still seeing transfers to WU. Now 2 hours later, the wireless signal strength is still 0, My Acurite is showing me readings from the 5N1, and WU is sending me emails telling me no data received in the past 2 hours. I'm about ready to throw this thing in the trash and forget about having a WX station in my yard. The sensor has been nothing but trouble since I first bought it in Feb 15.

I have had this problem in the past. I was able to get it to reconnect by hard rebooting the SmartHub (unplug for 30 seconds) then after say a minute or two, rebooting the 5n1 by removing its batteries, then replacing them and leaving the 5n1 in the room with the SmartHub. The signal strength shown on MyAcurite is useless, open your router setup page, find out the address of the SmartHub. The SmartHub MAC address is printed on the bottom of the device. The address for the smart hub on your router page will be in the form 192.168.x.x and then you input that address into your web browser and a page appears. The signal strength for each device is shown on a scale of 0-4. By refreshing this page periodically you can track signal strength to guide your placement of the sensors. This seems rather technical, i guess, but it is very useful information

OK, been doing all this over & over. Use LanScan to see the SmartHUB current IP address & point my browser to it to see the details. The 5N1 gets connected and only stays connected for a day or so before it drops the wireless link & I start seeing email notifications of no reports for 2 hours. Then restart both again and they'll stay connected for another day or so before dropping again. They are literally no more than 75' apart.

Sorry, the picture covered some of the text. The address for the SmartHub will be listed along with your other wired devices and associated with a LAN address in the form of 192.168.x.x. Input the LAN address into your browser. This can be done remotely (away from home, that is, off your LAN) if you know the PORT number assigned to your Smarthub. (I use a static IP address assignment for this reason) You must then use your IP address and the smart hub port number in the format IPADDRESS:PORT#    i.e 265.34.234.145:18

Only other thing i can suggest is trying to increase the distance between your router and the smarten using a longer ethernet cable. The high-powered interference from the router can apparently cause dropouts and the 5n1 is more sensitive to that than the tower sensors because its data stream is so much more complex.

OK, thanks. I'm a techie. I fully understand IP networking. I probe & diagnose IP networks quite often. Simple fact: 5N1 only stays connected for a day or two at a time before dropping off and needing to be restarted to get it connected again. There are about a dozen devices on my IP network. I use LAN Scan to manage them. That's not an issue. The 5N1 STAYING connected to the SmartHUB is the issue. Thanks.

The SmartHub and the router are in two different buildings, and on the same network. RF interference from the router is not an issue.

Smarthubs are HALFDUPLEX, which does not play well with many switches (esp 1G). It may be there are so many IP errors, that it is getting hung up dealing with those.
BTW what is the building structure material(s) between the SH and the 5 in 1?  Is the flat of the SH antenna facing the 5in1?

The only thing between my 5n1 and smart hub/access(now) is a pane of window glass. The sensor is on a post 75 feet away. My 5-N-1 stayed connected for 9 straight months until I messed with my router.

The SmartHub is stable 24/7. It doesn’t drop initiate a DHCP request. No issue there. The issue is the wireless signal between the smart hub & the 5n1, period. Nothing but a pane of glass between the two.

Certainly not saying you're wrong. I have switched to an Access now. Wireless signal from 5N1 says 4/4 most of the time and suddenly it drops. Not often in my case, but since I can't get to that location to fix it often, it is a pain in the backside.
