"no available sensors" when I have an active sensor with good batteries

  • Updated 5 months ago
My acurite 09150M hub sensor status was flashing constantly. I did not pay attention, as I had turned off our greenhouse sensor till spring time. However in December suddenly temperature charts were no longer available to house and studio sensors, while there had been no change in setup, status, etc... batteries are good. I removed the greenhouse sensor from the dashboard, no sensor status light kept blinking, and still no updates to house and studio readings. So I reset the hub, no change. I have removed the house sensor from the dashboard, to re-install it. However even though the sensor is active, it does not appear as an available sensor.

So something is very wonky here, that sensors are not registering are connecting with the hub. Any help appreciated.

I removed all devices from dashboard, and the hub, and powered down hub. I powered up hub, added it to dashboard, and the two sensors were available. 

I do not know why the sensors went offline and stayed offline, but I hope I do not have to re-install again, it defeats the purpose of having sensors to rely on while away.

marten, if this happens again, log DIRECTLY into the smarthub and see if it shows sensors (good signal, and battery).  I had this happen (no sensors) and I had to disconnect the network, then the power. doing only the power or issuing a restart from the device webpage, corrected this. only removing both cables, restored detection (3 devices)

Hello Steve, thank you for your suggestion and and sorry for late reply. How does one log directly into the smart hub? And I take it that it was the disconnection/powering off smart hub which reset sending signals to the device webpage? strange it should register devices locally, but not send them out. Thanks!

Hello Marten,

Here are the steps to log into the internal page of the smartHUB.

1.Open a web browser (Internet Explorer, Chrome, Safari, etc.).

2.Enter your router address in the URL bar. The default address for many routers is 192.168.1.1 --once you have entered this, press Enter on your keyboard. (If this is not your default address, consult your router's manual for the correct address.)

3.Most routers are different. Look for something similar to "DHCP List" or "Client List". These lists should contain the MAC addresses and assigned IP addresses to any devices connected to your router.

4.Locate the MAC address that matches your Bridge's MAC address exactly. This address will always start with 24:C8:6E

5. Next to the Bridge's MAC address, you should see the assigned IP address. Write this IP address down.

6. In your web browser's URL bar, now enter the IP address assigned to your Bridge, then press Enter on your keyboard. This should be the internal page of the smartHUB.

Hello Marten,

Is the smartHUB plugged directly into the router or are you using a port or switch? We show that it is offline again. What is the name brand of the router you are using? How far are the sensors from the smartHUB? What type of construction material is the house made of?

Hi Jennifer, thanks for the tips. I have moved my switch to after my router, and was able to plug directly into router. I will see how it goes. I have to say that the rechargeable batteries (am using EBL, only on the studio sensor and acurite bridge) are working very well, I will report back if they cause trouble. I sincerely prefer a reusable solution as the sensors and bridge do not have option for plugging in from household AC. It would be handy if that was an option. Thank you again for your personal attention to clients! It is what puts a business on top.

Rechargeable AA batteries have a lower voltage than alkaline or lithium batteries.  The lower voltage is known to be an issue for the sensors.

Thanks George. Indeed, I checked voltage on my rechargeables and it is lower than a brand new alkaline. However they seem to run fine at that charge level for the distances I have. I'll post here if I have any rapid loss of signal due battery drop.

It's not as simple as that.

Rechargables do not work well in this application and Acurite does not recommend their use.  

I guess you can do what you want, but don't be surprised when goofy things start happening.

Hello Marten,

We do not recommend using Rechargeable batteries in our products. Please follow the battery guidelines below:

You want the display and sensor to be at least 3 feet from electronics such as televisions, microwaves, computers & radios. Follow the battery guidelines below:

•Verify you are using fresh alkaline batteries or lithium batteries (when temperature is below -4oF/-20oC) in sensor.

•Quality brand batteries are recommended, including Duracell, Rayovac, Energizer, or Kirkland.

•Verify batteries are fresh. The battery expiration date should be at least 6 years out. Batteries can lose 3% power or more every year in storage.

•Heavy duty, extra strength or generic / store brand batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the way these types of batteries disperse power. Each battery should not exceed 1.6 volts.

•Rechargeable batteries are not recommended for use with AcuRite products because they may cause performance irregularities due to the voltage instability of these types of batteries.

•Mixing different battery types (brands, old/new, etc.) is not recommended.
