Purchased the Acurite Access to replace the old hub. Ran fine for first few weeks. Now goes offline daily and have to reset the device. Signal strength is excellent Battery Normal. Getting to be a pain having to reset it all the time. Oh yeah, the blue light is on.. Running the old hub with no issues.
I would really look at the surrounding environment for any electronics that can create noise. This could be speakers, WiFi or WiFi repeater, TV, PC, etc. My Access is located where the Hub was and it is performing much better for signal strength and just plain working. Since this has a receiver that captures data AND an Ethernet cable to sends info and gets commands from My.Acurite servers, if any noise is coupled into your Ethernet cable it might be getting spurious noise causing false actions to be taken. Unless you have run a shielded cable, wherever the cable is laid can have noise coupled to the cable..... I have a very short Ethernet cable (3') that goes from a IoPL 'cube' directly to my Access unit. Has worked fine for 3+ yrs with both SH and Access.....
for those not in the high tech development area, Signal and power integrity, EMC/EMI testing is a huge part for any electronic piece of equipment. All can cause devices to behave different and even fail. The issue with cables is they can be the weakest link in your system. Each component needs to go through EMC/EMI testing by labs. But the unit's SI/PI is internal testing that each mfg (like Acurite) needs to perform on their products. The Ethernet cables, is one other component that is not tested by Acurite since every customer's environment is different than another. I played with my hub (SH or Access) unit to get the best location I could find. Once found, it stays there and I tried to put in a place that was not easily disturbed by others.
Let's see, to get an Access device to work reliably we need gold plated, double shielded, CAT99X cable and keep everything in an RF dead zone. In the real world that I live in that kind of thing just isn't going to happen. Yes, a cheap, crappy, cable can lead to problems but that is the exception and not the rule. A "clean" RF environment just isn't going to happen with WiFi and BlueTooth all over the place Then, there's the RF hash generated by the network switch, PCs, local radio stations and every "smart" appliance in the house. New cables and relocating things won't fix crappy design and low quality builds.
I have the same issue. My 09155M Access unit loses connection with the 5-in-1 three to four times per week at 3a EST. Almost like clockwork, the same time it goes down. I have to do a full reset (remove power cord, remove batteries, reinsert batteries, etc). Ive sent 4 emails to customer service...not a word. I've submitted a request for an exchange...not a word. Really getting angry with Acurite at the moment. My Smarthub had no such issue but stupid me, trusted Acurite and ditched that unit when they forced the upgrade a couple months back, before they countered and said they would extend support until early 2019.
