Access versus SmartHUB for future smarthome integration projects

  • Question
  • Updated 5 months ago
We are working on various diy green home, tiny house, solar home, homesteading, greenhouse, aquaculture, and renewable energy research & development projects, and we are looking to deploy a versatile, low cost, temperature & humidity monitoring & logging system with multiple sensor types that can:

1. accurately & reliably capture temperature & humidity data and store in a database that can be queried and analyzed to determine performance efficiency of heating, cooling, and insulation systems - as well as allow collaborators to view the captured data points online

2. allow download & offline backup of captured data for permanent archiving and analysis in 3rd party applications

3. utilize battery powered wifi-enabled sensors so that they can be placed anywhere desired without power or ethernet cabling considerations

4. allow thresholds to be set for acceptable ranges and alerts to be sent to operational personnel

5. possibly support future integration into a smart home automation system created with the OpenHAB open source automation software platform

Our question is: which AcuRite hub is the better choice for our needs and why? The Access or the smartHUB?

Alan,

Regarding #3, do you mean "wireless" or "WiFi" ?

AcuRite's sensor suite is battery powered and wireless at 433 MHz.

WiFi works at 2.4 or 5 GHz and is more power consumptive.


Regarding your last question, in my view Access is superior in every way and it has the resources to enable future new features. The smartHUB is at the end of its design life. Hope that helps.

Hey John, I meant wireless on the sensors - thanks for clarifying #3. 

Sounds like Access is the way to go. Is there some really in depth tech documentation on Access that I can review? I have extensive IT and network engineering experience, so I'd be looking for something more than the basic consumer info.

Alan,


As far as I know, no deeper technical info has been posted other than what has been discussed here on the forum by beta testers.


First, those who have posted have happily noted that the battery backup and 12 hour restore of missed data to MyAcuRite in case of power or net fail is great. This is a feature that the old hub lacks.


We have observed Access using 100 M full duplex Ethernet.The hub was 10m half duplex, and struggles on gigabit networks.


The antenna on Access is improved, giving much more consistent receive performance. AcuRite does not claim range improvement over the hub, but I am very happy with what I see.


AcuRite is positioning Access as prepared to handle new sensors and new features for the future. Those of us who have studied the insides of Access see much greater processing power and much more program storage memory, and RAM. I think Access has plenty of resources to enable a good, long life.


Finally, those future improvements require over-the-air firmware upgrades. Access has demonstrated the ability to gracefully receive those OTA loads. It has been architected with reliable OTA firmware upgrade as a major design goal.

Cool! Sounds like their new flagship hub, so there won't be much on the internet until there is more widespread adoption and a body of early adopter experience.

Based on my current research, I recommended AcuRite on the TinyHouseResourceGroup Facebook group as a possible solution for a tiny house temperature monitoring problem.

QUESTION: would the user get a notification on her smartphone if her Access hub lost internet connectivity?

Alerts discussed here: https://www.acurite.com/learn/my-acur...

My AcuRite will send an email or SMS to a smartphone when an alert has been triggered.

Of course you need appropriate sensor devices.
