A while ago, I bought a small Dehumidifier for my wine cellar. I liked it a lot, so I bought another for our bedroom.
I saw some posts about people asking which Dehumidifier is supported by Home Assistant. This one is. The “Eeese Otto Dehumidifier”
This works with the LocalTuya integration.
There are many examples how to integrate LocalTuya in HA which can be found easily using a search on the net. So, I’m not going to explain that.
I could not find a configuration example, that’s why I’ll post that part here.
Pre config:
Install App on phone to connect Tuya device to cloud (one time only) You need this to extract the localkey
Add a developer account to https://eu.platform.tuya.com/ (Enable devices and change from Read to Control) (Get localkey from API Explorer, here is also a hint to be found about the entities) See below pictures
Install LocalTuya to HA
End result after config

Developer website information, where to find your credentials. (And a list of entities)
This is a Non-Cloud solution like Alexa and Google devices. I only could play with it for a few minutes because I was working on Arduino code with an ILI9341 Display and a BME280 (Temperature/Humidity/Air pressure).
Today I got some new goodies in, one of these is a LilyGO LoRa display which works on 433 Mhz.
I flashed OpenMQTTGateway on this device.
In the past, I posted about the RFCOM Gateway using Domoticz. This runs on a Raspberry Pi. While looking for alternatives, I found a rtl-sdr solution.
Get image from below url. Note! .. its a static non refreshing image!
http://192.168.1.2/album_art.cgi
Note: This gives me a file which shows fine in a browser, but being a http feed you cannot embed this in a https site. Another ‘problem’ with this image is that it includes headers, rendering this a invalid jpg when processing! (remove first 3 lines programmatically) I also want to have it updated, so I could make a mjpeg streamer for this. Probably i’m going to use my reverse proxy which uses SSL offloading to access cover art over https. (Then I can push this cover image on this webblog so you guys can see what we are listing to)
Another idea is to push this to an arduino display.
Not using https?
You can embed the album art in a dashboard. This won’t refresh, but the added time code will stop caching problems.
I’m running loads of housekeeping scripts on my servers.
I thought it would be cool to see states in HA.
Steps:
Log into your HA instance, and press your profile icon in the bottom left. Scroll to Long-lived access tokens, and create a new token. (Save the token string in a text file, you need it later)
Goto Settings > Devices & services > Helpers Create helper: Text and give it a name (bashnotification)
Next create a script in a path on your server, or place in an existing script directly. (Change SAVEDTOKENSTRING,HA-IP and bashnotification)
Below is a test with different methods. I like reading the booklets, so a CD i cool, and I don’t need a CD player. (The RFID tag is in the case) The little cards are for bought audio files I don’t have a physical CD for.
Wooden case with RFID reader being powered by external powerbank
What am I gonna do? Cube as I had? Wooden playlist selectors as in above movies? The cards I’ve printed? Maybe a small record player with an RFID reader inside?
3D printed like this? https://makerworld.com/en/models/66671
UPDATE: 20240327 – Little Record I 3D printed with little groves.
Home Assistant code for Playlist and Album automations (B.t.w. The method is still using an Arduino and MQTT topics, as mentioned before)

In the past, Aloha and I made a simple solution like this using barcodes in < 2000s. Due to the many obscure recordings I have, I am thinking about creating something like this for Picore player and my local Squeezebox server.
I used MCE to control some Windows VMs and programs running in it in the past. (Below link and a web interface engine which on the backend converted BWW/BMW (bagpipe music files) to PDF automated comes to mind)
Controlling a Windows VM using MQTT, very nice! (Use HA mqtt or mosquitto_pub in bash)
Question: anyone got a better solution to control programs within a VM? Let me know.
Next:
I’m creating a new case for my Wemos, LCD16x2, button, Led, Buzzer project (see other post)
I’m redesigning my previous case in blender.
But I really miss something like a generator function for different cases, like the one I made using Openscad. Question: Anyone know a tool/add-on to generate cases? I used a model of a wemos to get the usb connector/screw holes in place.
In the past, I’ve controlled some blender lights using python and MQTT. But now I’m trying to control it using DMX.
Example of lighting in our living using mock-up couch and tables.
I found a cool add-on called Blender-DMX. (B.t.w. wled can also use DMX)
Looks cool but, can I make a floorplan with this?
Blender add-on configuration
In Home Assistant I used a HACS add-on called : Art-net LED Lighting for DMX
Configuration can be done in configuration.yaml
light:
- platform: artnet_led
host: BLENDERHOSTIP # IP of Art-Net Node
max_fps: 25
refresh_every: 0 # Resend values if no fades are running every x seconds, 0 disables automatic refresh
node_type: artnet-direct # Which protocol to use
universes: # Support for multiple universes
1: # .Nr of Universe (see configuration of your Art-Net Node)
send_partial_universe: True # Only send the universe which contains data
devices:
- channel: 1 # first channel of dmx dimmer
name: dmx_dimmer_rgbw # name
type: rgbw # type
transition: 1 # default duration of fades in sec.
channel_size: 8bit # width of the channel sent to DMX device, default "8bit", "16bit", "24bit" and "32bit"
channel_setup: Wrgb # This is the magic to get colors correct
It works, but I’m not happy, anyone got a better solution?
And I have to check out GDTF profiles for fixtures.
At a later stage I’m going to 3d print a white floorplan about 1cm high, with LEDs and buttons. A floorplan you can hang on your wall.
Now, I’ve moved it to Home Assistant using a single automation. (Maybe the Arduino sketch can be made with Esphome also. But I don’t have time for that) It still uses the Arduino sketch as before, which uses Mqtt to post the RFID code to Mosquitto.
Not posted in the past, new version using ESPHOME and a m5stickc
Previous version using a ESP12
A “watch” with core and environment temperature of my smoker with a alarm, and button for timers.

For above i used sin/cos functions 2:3, which creates Lissajous figures. See: https://www.henriaanstoot.nl/1992/01/01/oscilloscope-graphics-using-a-amiga-bonus-vectrex/
