Enclosure for Wemos D1 Mini and environmental sensors

-
I've been trying for a number of weeks to find a solution to house a Wemos D1 Mini and some environmental sensors. There are lots of good options for 3D printed enclosures, and I read many posts like this, but I could quite find something that I thought would work.

Eventually I stumbled across this video, that showed a nice simple looking case available from Bangood. I purchased a couple of different sizes, which you can see in the images below. The smaller is 70x54x27mm, and the larger is 100x80x32mm.



I also purchased some of these mini breadboards, as I was hoping to make temporary connections between a Wemos D1 Mini and various sensors just using Dupont cables, so that I could easily change the sensor setup without having to resolder.


I've found these breadboards to be very nice for quickly hooking various sensors up to the Wemos D1 Mini, and you can see some examples below.



The smaller enclosure size was great for just throwing an ESP8266 and a sensor together quickly, and making it look reasonably aesthetically pleasing. However, I just couldn't find a way to mount the components in it so that everything fitted and was fixed nicely.

So, I decided I needed to use the larger enclosure for some semi-permanent sensor configurations. 

The next challenge was trying to get the micro USB port on a Wemos D1 Mini to align nicely with the existing hole on the enclosure. After much head-scratching, I realised that if I put some header sockets on the breadboard, then seated the Wemos, and attached the breadboard to the upper section of the enclosure, the USB port was at exactly the right height. See below.




I was planning to set up two enclosures. The first was to be mounted outside, and included a DHT22 temperature and humidity sensor, and BME280 temperature, humidity and pressure sensor, and a BH1750 illuminance sensor, in addition to the Wemos D1 Mini. I cut some holes for the BH1750 and the DHT22, and was planning to mount the BME280 directly on the breadboard. The sensors are currently held with double-sided tape, but I will use silicon if I need something more secure. You can see how I configured that enclosure below.






I'm also not sure how this enclosure will hold up outside. Although it is out of the weather, I suspect that over time some of the components will corrode, but it will do for the time being.

Next, I wanted an enclosure with another DHT22 temperature and pressure, and an AM312 PIR motion sensor for use in a bathroom. The setup for this enclosure is below.




So, overall they are a bit large and clunky, but I'm reasonably happy with the result. 

The Wemos D1 Minis are flashed with Tasmota, and the module configurations are below.

For the BME280 and BH1750 (which both use I2C) and the DHT22.


And for the DHT22 and AM312 PIR sensor, which I've also written about here.

Smart Irrigation Controller with Tasmota and Home Assistant

Image
I've recently been working on a smart, wifi-enabled irrigation or watering controller for my garden, and have finally got it up and running. I'll start with a picture of the finished product, so you know where this is heading. I had a few ideas for how to achieve this, and over the last few months I've been examining different options, and recently took the plunge and purchased some hardware. I've been doing a number of projects with ESP8266 based hardware, Tasmota firmware, and Home Assistant and so it was inevitable any solution I put in place would feature those elements.

Controlling Samsung Air Conditioner from Home Assistant

-
Image
I've gradually been connecting as many devices as I can using Home Assistant. One of the things that has been on my list is our WiFi connected Samsung Air Conditioner. It is a Samsung model AR24FSSSBWKN sold in Australia in around 2015. We have made use of being able to control the air conditioner using the Samsung Smart Air Conditioner Android app , but it has always been problematic. It consistently requires a username and password to be entered when using it outside of the home, recently it has stopped working inside the home, and it also requests some (in my view) unnecessary permissions (such as telephone and contacts). So, the idea of being able to control it via Home Assistant is appealing. I'd considered trying to set something up with my Broadlink IR Pro  to control it via IR, but most of the possible solutions seemed a bit clumsy. I became aware of the climate_ip custom component for Home Assistant  created by SebuZet who is active on the Home As...

PIR Sensor with Wemos D1 Mini and Tasmota

I ordered a couple of these AM312 PIR sensors from Banggood recently, to test using them in a multi-function sensor with Tasmota . There is some good information on configuring Tasmota with these sensors , and the manual can be found here . You can see an image of the sensor below, along with pin assignments. Thanks to the creator of this image; unfortunately I can't find the original source to offer credit, but am happy to do so if you reach out to me! These PIR modules simply behave as a switch. To experiment, I've simply connected the OUT pin to D2 (GPIO4) on a Wemos D1 Mini module, and have configured the LED on D4 (GPIO2) on the Wemos to turn on when the PIR sensor is triggered, as a visual indicator. You can see the setup on a small breadboard here. The configuration is Tasmota is here. Note that the LED is on D4 (GPIO2) but needs to be pulled high to turn the LED off, and pulled low to turn the LED on. Hence, the need to invert the signal using RelayX...
