SmartHub 09150 SmartHub Loses Connectivity

  • Updated 8 months ago
I don't find the design of the SmartHub 09150 to be very robust. If there is an internet outage, it does not reconnect on its own. The last time this happened, I had to power it off for two minutes, and then hit the "Activate" button. Of course, the purpose of having a remote sensor is to monitor my home when I am away for extended periods. In order to power cycle, hit buttons, or do a rain dance for the device, I have to be home. I don't understand why this device cannot recover automatically from a brief ISP outage.

Hello Mark,

We do appreciate your feedback, and will keep this in mind for future product development. You should not have to hit the activate button. If the smartHUB does not come back online on it's own we would recommend power cycling the smartHUB which is powering it off for 2 minutes. When you power it back up and plug it back into the router it can take a little bit of time to come back online. We would recommend waiting at least 5 minutes as that is how often My AcuRite updates.

It does do a DHCP request when needed, and typically it will come back just fine after a network or power problem.

I haven't had to press the "Activate" button except for a few times out of curiosity.  I think of it more as "the button that turns off the LED lights and screws up wunderground uploads".  

I have a few SmartHUBs that are about 700 miles away, and this year I haven't been able to get to them very often.  However, they still plug away without issue.  It might be because I still have them on a 10/100 network instead of gigabit, which can sometimes throw a shoe in the works if it doesn't negotiate down correctly.

Aside: The new Access links up to your network at 100 Meg rather than 10 Meg.  This side-steps the whole 10 Meg half-duplex issue and thus should play better with gigabit networks that can't reliably down-shift to that mode.

Hi George, thanks for the feedback. I think I may go ahead and try getting the new version. It's interesting that the existing one works in half-duplex 10Mbps mode. Honestly, I'v been designing electronics HW for years and you can't even get half-duplex-only Ethernet PHYs anymore....and not for a long time!

Yeah.  The hardware the SmartHUB is based on is pretty long-in-the-tooth.   7 years maybe?  It's using an embedded 10-meg ethernet controller in a PIC18 microcontroller.

The Access is a much needed hardware refresh to support future growth.

It's based on an ARM processor that is no spring chicken, but it does bring substantially more Flash and SRAM to the party.  512K of Flash (from 64K) and 64K of SRAM (from less than 4K) assuming I'm reading the datasheets correctly.

The new ability to keep logging data during a power outage is a much needed feature, too.  

John Z and I have been trying to nail down what chips are used in the Access today.  Why?  Just because we're interested in that sort of thing.  If you're also interested, send me an email to the address listed on this ancient page: http://nincehelser.com/ipwx/ and I can send you a few pictures of the Access internals.

Thanks George. As a side note, I looked up the Microchip PIC controller you mentioned. I browsed through the datasheet and didn't see that it operates in half-duplex mode. But I may have missed it.

Mark,

The part in the smartHUB is 18f67j60.
http://ww1.microchip.com/downloads/en/DeviceDoc/39762f.pdf

The datasheet says "compatible with 10/100/1000 networks".
Table 1-1, page 13 says what you get is 10BaseT.
Duplex mode is the designer's choice. See page 256 for that.

So far, I like what I see inside Access. Plenty of compute and memory resources, on a clean board layout.

Mark,
If possible, I would suggest plugging the smarthub directly into the providers router, rather than into your own wireless router (if you have one) first. I used to have mine on my Netgear router, and the smarthub would not come back until I power cycled either the Netgear, or the hub. I'm not sure why, and it took me a while to figure out that was the issue. Since plugging the Ethernet into the cable router, I have had no more hang-ups.

If you cannot figure it out, I would ask the cable provider to switch to a modem that has extra ports, and try that. Mine has 4 luckily.

Hi Acurite-Jennifer, It's a Linksys. The lights were off.

Hello Mark,

When you say they are off what do you mean? Are you pressing the register/activate button at all? The lights should function as follows: The left blue light is a network status light. It should flash for 1 second each time a reading is sent otherwise it will be steady. The right hand light should be solid steady. There should be an amber light in the back of the smartHUB that is flashing, and a green solid light.

Hi Jennifer, Sorry, I was referring to the side lights (the neon blue).

When I installed the unit, I seem to recall doing some steps to turn off the function of the neon blue lights, because they are so bright.

Hello Mark,

You can toggle the blue lights on and off by pressing the register/activate button for 10 seconds. Once this is done the blue lights should come back on. Let us know if there is anything further we can assist you with.
