I thought I’d pop this up here, as I’ve now had mine almost a year.

I’ve had sonoff zigbee sensors for a while, and wanted to try this slightly updated one with a display.
To cut a long story short:

  • It works
  • It communicates and pairs with HA ZHA integration out of the box.
  • I’ve not had any issues at all since I bought it.
  • The display is clear
  • The bracket sticks to the wall, then the sensor magnets into the bracket. The sensor also has a fold-out stand for placing on a surface.
  • After almost 1 year on the included battery, it’s showing 60%
  • I paid about £12, they’re now around £14

Battery use should obviously be taken with a pinch of salt, but I would not be surprised if it’s still trucking after 2 years.

Accuracy is fine for consumer level gear

I also discovered (after updating to HA latest) that temperature and humidity thresholds can be set on the device.
And that it will show symbols on the display when these limits are breached. By default, it shows a snowflake when it’s under 19’C.

So, yeah. For areas where people are likely to want to check the temperature quickly, they’re neat little dooberies.

    I am thinking about getting a motion detector and putting it in my mailbox on the inside back wall so i could be notified when the mail comes since i cant always see the mailman. The box is not directly in line of sight

      Have you considered mounting a door sensor (depending on the letterbox type).
      If it has a shutter, you could mount the two parts on the inside, on the edge.
      Do americans still use those flag things on mailboxes? As I guess you could also use a door sensor on the flag.

        I thought of a light sensor but a vibration sensor might work took. Does it correctly trigger if set to lowest sensativity? If so that might stop the rain triggers. However that might make it not trigger when it was actually opened.

      May not be enough motion to trigger. If he opens it to put the mail in,nyiu may be better off using a door/window sensor instead.

        @HiTekRedNek @shortwavesurfer That’s actually a good idea. We can go for days, sometimes weeks without checking the mailbox (it only gets ads). I wonder if there is a way to detect if the mail box contains mail, so it would just be a “You got mail” state, rather than "someone peeked into the mailbox.

        Otherwise a two-sensor setup. One for incoming mail (Perhaps triggered by something being pushed through the slot), one for when the mailbox is opened, to reset the state.
