this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....
What I didn't quite figure out was how it operates independently as a regular light switch.
What I find most interesting is that this is 8 years old. There have been some incredible advances in the IoT world in that time. I was about to do a similar thing which morphed into an ESP-12F then added a touch screen. I call it the Universal Light Switch
Imagine this: All the switches are identical. Any switch can easily be configured to control up to five devices ... and then changed, on-the-fly, to control a different set of devices.
My design is part of a system that would require a controller (eg. Home Assistant), an MQTT broker, and receiving modules in the devices being switched. It's WiFI which assumes an access point.
The DIY ULS is under $20 and the off-the-shelf receiving modules are under $10. (About the cost of a non-networked dimmer switch) If one doesn't have the controller and MQTT broker, they can run on an old (5 years?) computer (which is cheaper than an old RasberryPi).
This project is a good one!

Sorry, 1 more question. At what timeframe do you expect diy packages to be for sale? I have checked with steel manufactures before for other projects, but having a small batch of steel tubes means that they will be enormously expensive and the same goes for the PCB's. The milling I can do easily at a maker space (fablab013). I am planning on a rather long, 1 storey hive, so I plan to cut the metal tubes in half and mount an extension in between.
@zmatokan said in NModule:
@Nca78 Are you still working on this pcbs? i think it would be great to add a version that supports HiLink 220ac->5dc module on powerboard.
No I'm not working on NModules anymore, I have a few old nodes using atmega/nrf24 but I switched to NRF5 for "basic" nodes now, and to ESP32 for more "advanced" stuff.
NModule was designed for beginner and simple/riskless use, so I don't think adding high voltage option is a great idea, it's better to use an external power supply and connect the output to the powerboard.
@TON-RIJNAARD You need to select the board based on the bootloader you have flashed. Complile the code in Arduino and try burning the hex file using a programmer (USBasp, AVRISP, etc..) if are facing issues with Arduino.
Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse.
Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements.
The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.
@chbla said in Multiple uses battery RFM69 node:
Can anyone suggest a source for the parts? Are there any sources that you can upload the files by any chance?
If you mean can you upload a BOM to a company and then it generates a basket of the items, then i know that farnell and maybe digikey do this. But i only use this feature that is built into EAGLE pcb designer, so i'm not sure if they support it directly on their websites, might be worth a look.
