My front gate has joined the Internet of Things and is now controllable from my phone. The sliding door opener is a Beninca BULL 5M. The project is DIY, based on ESP8266 + MQTT and I can now open/close/read the…
IoT sliding door opener
BBoilRF
This blog post is about a project I have been working on lately, the BBoilRF. It is a general purpose internet-connected relay actuator/gateway with support for low power, battery operated remote wireless sensor nodes. It was designed primarily for use…
RFM69 to MQTT gateway using ESP8266
I’ve mentioned my plans for this project during the IoT hangout session few months ago, it has finally materialized as working prototype. The blocker so far was the lack of ESP8266 RFM69 driver and free time on my end, so I’ve…
Local hostname for connected devices
Now that we have connected our project to the local network, we are immediately faced with another challenge: how can we reach it? Using WPS/SmartConfig means we force the unit into DHCP settings mode, IP address is auto assigned by the router in…
Tweeting silicon
Here is a fun project for I did couple days ago: a tweeting ESP8266. The typical approach when dealing with such task (and probably the better) is to use a proxy service like ThingSpeak’s ThingTweet, PushingBox or by building proxy yourself with Node-RED or mqttwarn. It…
Firmware Over The Air (FOTA) for ESP8266 SoC
With the IoT booming nowadays, the number of connected devices grows exponentially and so does the related software that drives them. There is no doubt that Firmware Over The Air (FOTA) is a highly desirable – if not required –…
DIY Internet connected smart humidifier
I worked on creating a Internet connected humidistat last week using my open source WiFi relay project as platform. We observe quite dry air at our house, I suspect this is due to the fact that we use fan coils for heating/cooling. Humidity levels at home…
WiFi Thermostat with weekly scheduler
Edit: The project is now available for sale in my shop, you can grab one here: The WiFi SSR board project changed a bit and I use classical relays instead of SSRs now. The reason is that SSRs tend to…
WiFi IoT 3 channel relay board with MQTT and HTTP API using ESP8266
The ESP8266 DHT22/LED blinker project grew into an M2M relay board project with the following features in mind: Relatively small (10x5cm) PCB Powered via the onboard power supply or externally via a micro-USB plug Has three 2A Sharp Solid State…
ESP8266 powered web server + LED control + DHT22 temperature/humidity sensor reading
[Edit] Make sure to check my much more advanced example here The ESP8266 System-on-chip (SoC) has recently came out of nowhere and has been taking by storm the IoT DIY world. It is a $4.50 Wi-Fi capable chip that has remarkable specs, obsoleting…
