Onvis Home 4+

The sensor works fine as a HomeKit sensor, I only installed the app to get logged temperature data off the app.

Two problems, one is that even though it has two months of history, there seems to be no way to download it all at once. You can only email yourself a csv file one day at a time. Which makes incredibly tedious to use for pulling those logs (and motion data and humidity are separate, so you’d have to do it three times for each day).

And just for fun, the logs have the wrong data. The data log shows exactly 30 degrees F colder than the actual temperature, so in addition to a several tap process to email yourself the logs 365 days a year if you want to get the data off continuously, you’ll need to add 30 to the logs on the other end. Mystifying (C is accurate apparently)

First off, the device itself works beautifully. The battery compartment was a little bit of a hassle to open the first time. I really like the fact that there are three sensors in a single package.

For some reason, as of today, the app has begun to crash instantly upon opening. I was able to use it before it began this behavior. It seemed somewhat good for first version. My only suggestions for the app would be to work on the account creation screen. The keyboard blocks the ability to finalize account creation and there is no way to minimize the keyboard to allow access to the button. It would be nice to have the app show data point intervals of smaller time instances. I would suggest like every 15 minutes compared to every hour like it currently does. It’d be extremely useful for more accurate trending. Oh, one other suggestion would be to have the ability to export our sensor data so the user could use it for something like trend analysis of a particular room in their house. Currently I’m concerned with the humidity levels in certain bathrooms of the house and would like to be able to use comparative analysis in some sort of database software.

Final verdict, buy the room sensor for the information it can tell you but don’t depend on the app itself so much. Hopefully the developers are able to work on making it a more usable app in the near future.

The device and app are great when it works, which is less than half the time. The app either gets stuck with an hours old temperature, gives an incorrect reading of 32 F for the whole day or the app says the accessory is unavailable. But in Homekit, it displays the proper temperature. I was counting on the app to give me a history of temperature but not with the current state of the app.
