Athom Human Presence Sensor mmwave (share your experiences)

Thanks for pointing these out. Nice and cheap so I think I’ll grab a couple and see how they go.

I wonder how easy/hard it will be to chip swap it to an ESP32 so we can include a BLE proxy…

Mahko_Mahko · July 13, 2023, 8:49am

Not sure how the certification is on it or how that works?

The Athom AU smart plugs aren’t certified.

But I guess you just need to swap the adapter if it’s not certified and that’s a concern?

sparkydave · July 13, 2023, 12:37pm

Yeah, it’s just USB powered so a locally purchased adaptor will satisfy the certification side of things for Aus.

Just got mine last night, works great. PIR is super fast and mmwave seems to keep lights on. Does anyone know what each of the adjustable parameters is for?

Aiden on Discord mentioned these would swap out.

They commented:

The shield should be removed, otherwise the back cover cannot be closed

Any chance that zones can be built for this one? This is one of the really amazing features of the Aqara.

Generally, you only need to adjust the detection distance, maintain sensitivity and fade time, and the other parameters are defaulted. Followed by the value range and default value

Here’s an improved configuration for the sensor

Changelog

now stores mmWave configuration values as it is supposed to
add PIR delay in substitutions to configure no occupancy delay on PIR motion and Occupancy sensors
change Occupancy sensor logic to make sense
smaller steps for configuration options allowing finer grained configurations
sliders with too many options switched to number boxes
remove on trigger delay of 50ms for even more responsive triggers (no idea why they’re set in the first place)
set button to internal since its a reset button and hard to reach
remove factory reset button from HA device card, if you really want to reset use the web UI or the button
disabled by default these diagnostic sensors: MAC address, SSID)

Does anyone have experience on how it compares to the everything presence 1? I’m tempted by the price. Lewis’ device is feature rich and offers a humidity and temperature sensor and with the ESP32 also Bluetooth, but how does the PIR and mmWave sensor compare against the Atom sensors?

sparkydave · July 22, 2023, 6:00am

My two arrived a couple of days ago so will hopefully get them up and running this weekend. I’ll report back.

blakadder · July 22, 2023, 12:24pm

It doesnt since Lewis used a 20$ sensor and athom used a 2-3$ one. athom has detection of a moving thing, EP1 has so much more especially with the latest beta software

Mahko_Mahko · July 23, 2023, 8:38am

Are you able to confirm which sensor they use please?

blakadder · July 23, 2023, 9:05am

Mahko_Mahko · July 23, 2023, 9:29am

Do you know the name of it? I don’t know if it is supposed to be obvious, but it’s not to me;)

Aiden1 · July 28, 2023, 10:19am

It seems that you changed the judgment logic of the occupancy sensor. In your judgment logic, Pir does not play a practical role. The purpose of using Pir is to avoid false triggering in complex environments, such as placing the sensor near a window, and the curtain will cause mmwave False trigger. The delay of 50ms is to eliminate GPIO level jitter, and the actual experience of 50ms can be completely ignored

blakadder · July 28, 2023, 11:39am

Yes, that is correct.

slace · July 30, 2023, 5:18am

How are people finding the stability of it? I have a few of the AU plugs and I find they drop from HA every minute for a fraction of a second, so my logs are full of “plug unavailable” then “plug available” a moment later (and this makes it hard to do automations).

I get that it’s cheap compared to an EP1, but I wouldn’t mind a few cheap mmWave devices to help cover the dead zones that I have (and a fully featured like EP1 for the “primary” in an area).
