Athom Human Presence Sensor mmwave (share your experiences)

Mahko_Mahko · June 30, 2023, 10:20am

I just saw this pop up and can’t see any threads or info yet.

Any experiences or even just your 2 cents?

From some folk in Discord.

Inside may be this sensor.

This may be the config.

I just one today and set it up. Pretty easy to join my WiFi network and automatically appeared in HA. Lots of settings to play with. First impressions: PIR is super quick, mmWave sensor too. It has a light sensor built in too. No zones support.

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

sparkydave · July 13, 2023, 5:50am

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

Merc · July 16, 2023, 7:07pm

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;)
