      Ive had mine for more than 4 months and still showing full battery. I dont connect via bt too often but screen is always on.

      Sounds like you're using one of them non-Eneloop brands.

      •  

        Should I be using an eneloop or an ordinary energizer would be enough?

    •  

      I've had mine for about six months with the battery it came with, it seems to think the battery is still full?

  •  

    Thank you op. Bought one.

    Got 1 from last deal, just a warning that even though you could add this to your gateway, you will need to be in Bluetooth range (ie within your home) in order to use mi home app to connect to this. :)

    •  

      strange functionality… are you able to review the temperatures and set it to control things via openhab/HA? even if you are out of range?

      •  

        When you’re out of home you could only see the temp from the last time you connect :). You could still add automation so I guess it’ll work out of range, not 100% sure as the text in automation is still in Chinese so I don’t bother trying. :D

        Load up bluetooth on HA and you can talk directly to the devices (mac addresses go in the HA config)
        Alternatively, get a bedside lamp or something else with a BLE and have the BLE connect to the Gateway and the bluetooth devices tether off the ble gateway.

    •  

      Are you sure? What's the point of the gateway then?

    Anyone know if these are accurate? I have heaps of cheap sensors of both types but they all give different readings so I can't really trust any of them. I need an accurate one.

    • +1 vote

      I'd like to know that too. Most cheap temperature sensors are accurate to within half a degree or so. But most cheap humidity sensors produce nonsense numbers. I've had a few, and without exception, they're rubbish. I can put them in my greenhouse, which is super-humid, come back half an hour later, and the numbers haven't changed much at all.

      If this is accurate, I'll buy it. But I don't have high hopes.

    •  

      It’s pretty accurate, precise to one decimal for both temp. and humidity, I use another brand get pretty much same result.

      •  

        Thanks, bought one.

        Number of digits does is not accuracy. That's precision which is useless if the device isn't accurate.

          I remember this from Year 11 Chemistry :)

    •  

      I have had to test a lot of sensors for work purposes I would recommend the Honeywell Leak detector via Lyric app reads temp humidity with a running accumulation of this data in the app and detects water leaks, long battery life and very accurate but the downside is it's not cheap.

    Has anyone managed to get the historical temperature to work? I have only managed to look at current temperature and humidity with this. Do you need a hub to record historical data? Or do you need to be more regularly connected to it? Where is the data actually stored?

    • +1 vote

      There is no historical temp unfortunately :(

      •  

        That's what it seems but I have definitely seen screenshots of the app that suggest it can. If I remember, there was a YouTube review that showed that feature. Never been able to get it myself.

        •  

          I'm asuming there must be a smartphone app that records the current temp at regular intervals, and that is what constitutes the historical data. Would most likely kill your battery life to do this though :/

        •  

          May be that's screenshot for the other xiaomi thermo without screen?

      These devices are bluetooth and do not store historical data. If you want to track the data, require a Xiaomi Gateway + a BLE gateway*

      You also probably want something better than Mi Home for the automation, if running Home Assistant etc, load up bluetooth modules and can communicate directly to them. Just need MAC address and name them properly in config.

      *BLE gateway is found in the bluetooth bedside lamp

      Stand-alone; no historical data.

    •  

      I want to know this as well. The connection through Bluetooth to phone is pretty slow. The Mi app is very slow to load.

      I bought this thinking you could get historical data (with just the app, no gateway etc).

      It's a great little device, but in the end pretty disappointing unless you're looking directly at it.

    • +1 vote

      disappointing too, bought it for historical data as seem on the screen shot on app to.

    •  

      Without the gateway, it is definitely NOT possible.

      With the specific gateway (bedside lamp), it SHOULD be possible, however the post from NTB above suggests that even with the gateway, it is not possible - but this seems wrong?

      •  

        does the 6 in 1 or 5 in 1 kit have that gateway that lets the device connect to it?

    •  

      Iirc, you have to tell the app you're in China, then you get the graph. But I found it rubbish for any practical use in my house, but keep it near my a/c controller so I can see the temperature (which my a/c doesn't show)

  •  

    Any backlight for this? Thanks.

      No backlight

    • +2 votes

      Negative. It's a low power device.

    •  

      there's an e paper version that looks like it might be lit.

      If you have backlight on this, battery will die quick since it is on all the time.
      unless there is a push button for backlight

      but then you are already looking it directly,
      so pointless.

    does this have a magnet that sticks to a fridge?

    •  

      The clip that you screw into the wall has a chunk of metal in it.

      Back of unit is magnetic; so will stick to your fridge.

        It’s a tape, no screw.

    wasn't there a temp sensor for like less than a buck last year?
    this seems expensive

      With Bluetooth and connectable to a Bluetooth gateway? Yeah nah.

    Bought one for the kitchen.

    Thanks OP. Now I can check the temperature from upstairs before heading down!

    Bought One. Thanks OP. Great for traveling when in the sauna in the hotel
