### 5/5 — WoW super product

*2024-01-08*

Excellent product and good costumer services !

### 1/5 — Wow this is buggy!

*2023-01-14*

Graphs don’t scale nor pan (contrary to the description), each download creates a separate log rather then just add to whatever sensor data is already stored. Messy!  CSV export has all sorts of config data on top so needs to be removed each time you use it. Annoying!   For such a little app, this could easily be done right.

### 4/5 — Nice so far but: P_avg glitch? alarms?

*2022-12-21*

Just started using this; was using Govee & SensorPush.  
It's great to have Pressure, adjustable sample rate&start, small form factor
Seems like stats glitch gor small log count: average pressure shows up at about 50% or 80% of actual value.
also, are there available alarms notifications sendable to phone, e.g. if temperature exceeds set limit? 
is that done with Commands?  Thanks - nice products
I have Tempo Discs

### 3/5 — Weak

*2022-03-29*

Doesn't even carry over settings when switching to a new phone.

That on top of the very unreliable yet expensive sensors, I really wish I did better research before buying.

### 5/5 — Great app and products

*2021-09-20*

The Blue Maestro app works seamlessly with their Tempo Disc products. I set one of mine outside full time and can get the data to easily track my weather conditions in a spreadsheet on my computer. I also use the app to see what the disc observes when I put it on a drone to take a vertical profile of the atmosphere.

### 5/5 — Tempo plus2

*2021-03-22*

This device is amazing not only is it fully portable but it gives an accurate temperature of where you are not the temperature of a suburb! If the aircon is not working you can find out and get it fixed when it suits you.

In short this is probably the best app I have ever invested in.

### 2/5 — Glitchy

*2021-01-13*

Every time I download data from the device, it shows a spike and then a dip in temperature, humidity, and dew point that gradually levels out. I know it’s not correct, so I ignore it and look at the other data. But it messes up highest and lowest readings. I think this is a bug they could fix. Not sure if the devs read these reviews.

### 5/5 — Great app

*2020-11-17*

Works with my Tempo disc. Easy to use and setup. I monitor my RV freezer, refrigerator and storage compartment. Let’s me know when safe to put food in my unit and monitor my storage area so that my hose doesn’t freeze.

### 5/5 — Performs exactly as advertised

*2020-10-11, version 8.2*

Great little sensor with a multitude of setting options. The unit works fine and the software shows the output on any number of devices. Perhaps the UI could be prettier, but thats a minor point.

### 1/5 — Rubbish app

*2020-07-10, version 7.5*

Tried two email addresses to Register, verification code not received, checked spam folders of course. Multiple times. Then can’t register again as email addresses are already registered so stuck now. Fail. Rubbish.
