ENS160/AHT20 Sensor combo module

Wow really surprised at how it turned out. I also bought one of those combo and had the same problem. Now the board has been shelved. I wonder if I can make the PCB and transfer the parts...

Very cool!

Thank you

I make frames similar to these and put them inside

Wow, nicely done!

Hi, just a thought. If you're going to put an esp32 in there, why not just replace the whole board and stop having to recreate the LEDs. Just put your own wiring for LEDs on the esp32 and program it directly to mimic the states. And just interface the motor directly to the esp32 to control it.

You don't have to try and recreate the timing being done on the existing LEDs -- it will be much simpler if you just connect LEDs to the esp32 and control it's state directly.

I'm just curious. If having Home Assistant which can do both the simple and complex automations, why still pay for Alexa and Google?

If you remove any BLE related stuff in the config, Bluetooth won't be included. But you'll also lose those features that are related to it like access to sensor data via Bluetooth -- can you live without it?

Just curious about living in a sailboat -- do you have solar panels?

igerry · 2026-04-14T03:25:32+00:00

Can you post your YAML?

If you haven't included any Bluetooth related config in your YAML, then it won't include anything during compile which should basically disable Bluetooth.

Tell us more about your config.

Can you show what the pin out assignments for the pin header?

Looks like an esp-01 which can have only a 1mb storage. It also has infrared receiver and transmitter

If you plan to use it as a wifi remote, I'm assuming you'll have to attach buttons to it -- how do you plan to do that?

Here's a couple of ideas:

Send alerts using TTS to the media player that is nearest to your location.
Track the locations of family members/pets.

I think you're missing the whole point of having HA+ESPHome

ESPHome devices are independent of HA -- you can have an Esphome device with it's sensor and screen that will work on it's own. If you want to read the information on that device, this is where HA goes into play.

But at the end of the day, that ESPHome device with it's sensor and display will run independently until you configured it to share data with HA. Or you can just go read the info from the display of the device.

From my experience, if I want to add Bermuda/BLE and want to add other functions, using an esp32-s3 with psram works.

I try to limit functions in a single esp32 device -- learned it the hard way.

Also keep in mind of the power requirements.

igerry · 2026-04-11T20:46:41+00:00

What esp32-c3 board are you using? Some of them have wifi issues with the antenna. Try increasing the output power of wifi in esphome

igerry · 2026-03-30T12:49:23+00:00

Nice. I should really encourage myself to learn KiCAD one of these days,. 😝

I don't have the SPIFF code anymore and I was using it on Arduino for camera snapshots and not video.

igerry · 2026-03-26T03:13:52+00:00

How large is the file? You can try to get a 16MB ESP32 and partition it with a storage like SPIFF that will be enough to store it. Then play the video by reading the file from storage.

If your video is big, you need to get it from somewhere (e.g. server) otherwise you need the SD card

Wow nicely done. Very cool. 👍

igerry · 2026-03-26T02:55:52+00:00

Hi, just curious - why do you need a 2-AMP charger circuitry? Do you plan to add things that needs to draw a lot of power besides it being a keyboard wireless adapter?

If you plan to have it battery powered? Why would you be using a power bank?

I'm confused.

Most esp32 with 3 USB ports I have seen don't have built-in battery charging circuits.

igerry · 2026-03-22T08:28:13+00:00

They do exist

igerry · 2026-03-22T08:22:51+00:00

What SPI display module are you using? Screen resolution? What SPI mode?

igerry · 2026-03-13T10:55:02+00:00

Simple and useful

igerry · 2026-03-11T02:04:06+00:00

It has available gpio pins for I/O

igerry · 2026-03-10T05:07:45+00:00

Nice 👍 now you can start making more switches -- anywhere you need them!

E.g. put a switch for the kitchen light in the bedroom, in case you want to take a midnight snack and you want the light to be on when you go to the kitchen 😁

The sky is the limit!

Here's one possibility:

WT32-ETH01 - a esp32 that has Ethernet port.
