Shipping of DIN Rail Monitors

Dear backers,

Thank you for your patience while I got the production of this new design streamlined. The major hold-up was in the very low yields on boards using 0402 parts. Hand assembly of these was reaching the limits of my production crew and lots of rework and verification had to be performed. I over-built the units and have sufficient at hand to meet the order levels.

The firmware to be loaded on the DIN rail monitor can be found here: https://github.com/whatnick/ATM90E26_SPI_DIN_Wemos

If you would like any features included in the firmware, please lodge issues there or send me pull requests. I will also work on a quick-start guide for the monitor. I have working firmware for this board in both Micropython and Arduino. However units will be shipped with Arduino firmware pre-flashed. The firmware also supports http OTA upgrade.

I attended the Linux Australia conference and demonstrated the energy monitor and in a small way enabled Micropython support for the 16MB Wemos used on the monitor. Open source is all about collaboration.

Finally a shout-out to SANE Makerspace for providing a good work environment for the last stages of testing and assembly.

Manufacturing is not glamorous, it is often filled with disappoint and unforeseen challenges. We have had a fair share of ours and overcome them to ship a working product. Keep in mind this is an open system and you are free to change the firmware and modules that form the hardware. Small tweaks to the hardware are being loaded over OTA and units will be shipped to CrowdSupply via DHL tomorrow.

$15

ATM90E26 Breakout Board

A breadboard-compatible ATM90E26 module I made to save myself hundreds of dollars, which earned me a mention on Hackaday. Now it can help you get started with energy monitoring as well.


$30

ATM90E26 Breakout Kit

All the parts you will need to use the ATM90E26 on a breadboard to build a self-powering energy monitor with Wi-Fi connectivity. A NodeMCU and a 100 A YHDC current clamp will be included as part of the kit. Voltage sampling transformer is the only other part the user has to supply.


$35

Energy Monitor FeatherWing

A hacker-friendly, low-voltage dev kit for the ATM90E26. Compatible with most Adafruit Feather-series boards and accessible via SPI or UART. Two can be stacked in SPI mode for grid + solar single-phase monitoring.


$70

Energy Monitor FeatherWing Kit

An Energy Monitor Featherwing with some essentials to get you going. The Adafruit Feather and a 100 A YHDC current clamp will be included as part of the kit. Voltage sampling transformer is the only other part the user has to supply.


$60

DIN Rail Energy Monitor (Single ATM90E26)

Something your electrician will feel good about installing. A fully featured DIN rail module with options to install two ATM90E26 monitoring boards for grid + solar. Can be interfaced with Wemos (ESP8266) footprint boards to add Wi-Fi, BLE, LoRa, and other forms of network connectivity.


$20

ATM90E26 Secondary Module for DIN Rail Use

Secondary module for the DIN Rail Energy Monitor above which will add another phase into the monitoring setup. Essentially the same as the breadboard version but with isolated SPI bus making it suitable for use with high-voltage inputs. This module can be used to measure a second phase or single phase solar output after the inverter. You can also use it to design your own isolated high-voltage monitoring system.
