Hey

I’ve just installed my first one (DIY, sorry ) below the TV and it works perfectly!

Thank you for sharing your project!

I could make a small donation if you wish.

Cheers

Hi I had purchased a few 1w units but not sure how to setup and initialised once received the product. I had tried to use the yaml in screek-human-sensor/1w/yaml at main · screekworkshop/screek-human-sensor · GitHub

Do you have step by step guide for 1w setup?

Thanks in advance.

[screek-workshop]

hi, you can join us group.We have refined the 1u firmware to simplify the way external components can be used. But 1w we will need a little more time.
We’ll post it in our group when the time comes.
Currently if you just need to connect to ha, you just need to match the network and then ha will be found. No code needs to be written.

I purchased one and it works so well I have purchased another.

One comment I would make is that you may want to tune the sensitivity by using an Automation that looks at changes in the Still Energy exceeding a Threshold and triggering an action based on that rather than Presence.

It would be ideal if I could set the threshold that triggers both Still Target and Presence to be Detected but this workaround works.

You can adjust the still and moving thresholds via the HLKRadar Tool app via bluetooth.

LD2410 esphome tips

If you have the LD2410B/C you can use the HLKRadar Tool on your phone to connect to the LD2410 via Bluetooth and you can do all the configuration there. It allows you to set the distance and sensitivity. The following post near the top of this thread has the link to the tool for Android phones: Tweaking the sensitivity for each distance gate is a little tricky. Make sure that Engineering mode is turned on and you should see the graphs in the HLK app. The pink/red line on the graphs is the ene…

Thanks for the prompt reply. I think I messed up the configuration and try to install the yaml from github source again but return with the follow error.

I bought one of these and it was as easy to set up as being mentioned here. The problem I have is that I have no power outlet in the toilet I am now planning to use it in, is it possible to power this thing with battery instead ?

[screek-workshop]

I’m sorry, but I’m afraid batteries are not a viable option considering the relatively large amount of power required by the device. The radar module is a sensor that generates a lot of heat and consumes a lot of power, and the usual operating current is up to 70ma, while the esp32 in the RF section is also very power hungry.

i got my one a couple of days ago. wondering if I can use the Screek Human Presence Sensor 1U Sun Light state as a condition when running below automation. currently, it is on a time base.

such as if the sun light is below 5% then light will come on and go off if it is above that . it is like when we open and close the curtains in the bathroom lights should come on and go off if the sunlight state is between 0-5

I guess if the brightness of the light is almost constant then this looks possible, this light sensor is very sensitive to daylight but very sluggish to artificial light. But it can distinguish between 1’s and 0’s, which is an interesting phenomenon. So I guess it’s an interesting idea.

If you received it recently, try updating to a newer firmware using ota, it performed a little better in our tests.

[chrisvor (Christos Vorkas)]

Hi. Just received my first 2 units. Installed the 1st one and connected it to my WIFI and all was well!
I then created a new ESPHome source file, using the yaml from your github page, added my network credentials etc in the source and compiled a new .bin file. I browsed to the device and used the OTA Update button to upload the new .bin file. After a short time, it came up with a “cannot display page” error page in the browser.
Now the device does not connect to the wifi, I cannot update via USB (it says that I need to hold the BOOT button while connecting, but if I try to do that, as soon as I select the port, it says the device has disconnected).
The device is not dead, as I can see it via bluetooth (it was discovered by HA and I configured it) and the “Motion” and “Occupancy” sensors work well.

Can you please help revive it?
Many thanks!

[chrisvor (Christos Vorkas)]

False alarm! I assigned a static IP to the device via my router, and the device now connects to the WIFI. Must have been a problem getting a DHCP address .

However, it is still on the original firmware.

When I try to OTA Update again using my firmware, I see the below in the scrolling log:

OTA Update Start: screek-presence–tv-room-factory.bin OTA in progress: 0.1%
OTA Update failed! Error: Wrong Magic Byte

Any ideas?
Thanks!

[chrisvor (Christos Vorkas)]

Even if I try to use OTA Update to upload your updated binary (ota-screek-humen-sensor-1u-20230704_1.bin), it progress to update 48% and then the browser shows a “cannot display page” error.

When I restart the device, it is still on the old (2023.5.1) firmware

Please help…
Thanks!

[screek-workshop]

I apologize that since we weren’t in the community in time, the community can’t seem to send a forum reply email to me, which is odd.
OTA update please try leaning very close and letting the sensor cool down for a while before trying again. (ref to this)

this is cause by try to rewrite firmware to custom firmware, but with diffrent ota password.so you had doing once factory flash(by usb) to kick in you custom firmware.

OTA Update Start: screek-presence–tv-room-factory.bin OTA in progress: 0.1%
OTA Update failed! Error: Wrong Magic Byte

For initializing the flash to factory factory firmware, you can use the two-flash method. We mentioned this method in github. Plug the usb into the computer, then github download to the usb device, the first time it will fail, wait a few seconds, the device will enter the flashing mode, and then write again, there will be a chance to succeed.
If this doesn’t work then you need to open the box, hold the 0 button and press rst to enter dfu mode, then esphome will write.

We’ll do a guide on this soon if possible.
The s2 mini will be slightly more tricky on this side of things due to the fact that the usb-cdc is enumerated by itself, unlike the c3.

Also on the sensor itself you are welcome to join our fb community, we can always get push messages in there.

@screek-workshop I bought 2, and they worked really well! Thanks!

Would you consider making one with mmWave sensor that can monitor heart rate and breathing?

Seeed 60GHz mmWave integration using ESPHome

I have quite a few working 24GHz mmWave presence sensors in my home and have made some solutions for others as well but I was very excited when I learned of the 60GHz models from Seeed. So much so that I purchased both the heart/breath MR60BHA1 and fall detection MR60FDA1 variants without a second thought. As is my MO, I had no idea before they arrived, how I was going to make them work I played a bit with the example code from Seeed’s GitHub that works with Arduino IDE and even …

[smugleafdev]

I have three Screeks and they all seem to overheat and disconnect from wifi after a few days. All three of them. They’re in pretty regular areas in the house, out in the open. Any ideas? Are they just defective?

This graph doesn’t look good.

EDIT: Updated from 2023.5.1 → 2023.6.3. This probably fixed it. Also apparently it’s suggested to cut new holes into the old 3D printed case, as there are not vents.

[screek-workshop]

yes, update the new firmware will get help: OTA Update - SCREEK WORKSHOP

The new design housing is now available: SCREEK Personalized enclosure Type 1U-BOX-B for 1U | eBay

If you have a printer, you can ask us for the stl file and print a copy yourself, it will save you cost and time.
We designed 1u in January when it wasn’t so hot, and parts of the summer that were very hot seemed too hot.
We have recently added cooling enclosures.
All subsequent 1u’s will have heat sink configurations.

Thank you for your support.

[smugleafdev]

Looks like the firmware is the primary solution, but they still get up to 115-120ºF. No more crashing though!

I do have a printer! May I have the .stl? I also have a power drill and experience at adding holes to PLA and may go that route just to be lazy.
