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.
This is actually really helpful. I have a cheap one from Tuya, that also has a display, but the battery is empty after like 2 weeks and I don’t wanna keep constantly changing it, so it’s always off. This sounds like a great replacement.
I keep wondering if I should open a little non-profit shop, specialising in “cheap home assistant stuff that isn’t awful, that I’ve tested”.
Then I remember the absolute chaos involved in running a shop…
I only go Tuya if there is absolutely no Zigbee alternative. I’ve got curtain bots on Tuya which were fine when it was one curtain but now they barely respond to automations anymore.
And you could probably replace whatever Tuya does with Esp32;)
Tuya make Zigbee products too… They’re just not good Zigbee products. I don’t think they’re officially Zigbee certified and have some weird behaviour, similar to some of the older generation of Aqara devices (their newer ones are fine though)
@dan Agreed. For probably multiple reasons, TUYA products have not been sufficiently reliable for my projects.
We have this in the living room. It uses 3 AAA batteries and they’re still 90% after several months.

Would you say they’re accurate enough? Ive been thinking about getting something like this especially now that the temperature varies so much here in the UK.
Seems about right to me.
I mean, that’s where all my sensors are, and they’re doing OK.
My outdoor sensors are classic 433mhz meteorology ones though, as I didn’t want to mess around waterproofing zigbee gear.
