Sonoff S31 - Low Cost Energy Monitoring
Everyone wants to monitor energy consumption. Everyone wants to automate their home.
The Sonoff S31, is a pretty low-cost way of doing this.

This is a very quick post on how to take a sensor- such as sensor.grid_power
and split it into sensor.grid_power_in
and sensor.grid_power_out
.
This can be handy if you need a separate sensor for energy/power in, and energy/power out.
For this short post, I will be splitting sensor.battery_power
into sensor.battery_power_in
and sensor.battery_power_out
This is a quite guide on creating a real-time sankey diagram to show your current energy usage.
Starting your A/C compressor generates a massive inrush current. Many inverters will have issues getting the motor spinning.
In the case of my 3.5 Ton unit, the L.R.A. (Locked rotor amps) is 112.0 amps @ 220v (24,640 watts). This is far more current then my inverter can provide. This is the amount of amperage which it can potentially take to start the compressor motor.
This post, describes how to install a soft start, which will allow your compressor to easily start off-grid using your solar array with inverter and batteries, or via a smaller generator.
Part 4 of the home solar project. Adding monitoring tools and hardware.
Will be adding Iotawatt for per-circuit energy monitoring, and solar-assistant for monitoring the performance of my inverter / batteries.
Per my home solar project, I needed a method to collect data from both my batteries and inverters, in near-real-time, with no dependency on the internet.
Since, my inverter's connection relies on cloud applications to move data around, I decided to give Solar Assistant a try after reading of its support for the solark-12k.

I just swapped my TrueNAS from a Dell R720XD over to a Dell r730XD. During this migration, I moved over my NVMe drives, NICs, and everything else relevant.
However, after firing up TrueNAS on the new hardware, I noticed my 40G NIC was not listed in the list of devices!
After once again googling how to change the mode over, I figured I would just quickly write some documentation incase this happens again in the future.
Last week, I added a 10G Unifi aggregation switch to my network.
I noticed a few potential performance issues, and decided to track them down.
This is a simple guide, with a few methods you can leverage to troubleshoot network performance issues.
A quick guide on how to set common options with the ConnectX-3, via linux, without using the OFED driver.
This guide is specific to ethernet mode, but, may or may not work with infiniband mode.
My r720XD took its last breath earlier this week...
This is just a short post about its troubleshooting, and.... what will replace it.
Tonight, I wanted to do a small, random side-project. I automated the galaxy!
(Or, at least a small version of it.)
Creating simple sensors to determine if we are "at work". Includes setting up a work_days sensor, time of day sensor, and a template sensor to tie everything togather.
As well, includes steps for handling vacation / OoO days, and holidays.
As apart of the Home Solar Project, I purchased and assembled an EG4 battery rack.
This post outlines the process of assembly, issues I encountered, and my final opinions.
For the second part of my Home Solar Project, I researched possible solutions and ordered batteries.
This post, describes some of the decision making process I went through.
One of my projects I have been working on over the last two years, is adding solar panels to my house to offset some/most of my electrical usage.
Here are the goals I wish to accomplish, and how I plan on accomplishing them:
Using a Tp-link kasa HS300 as a low-cost switchable PDU. This product has features for per-outlet power monitoring as well.
On this blog / my house, I try to use 100% local control products whenever possible. Many people don’t understand the reasoning behind this…. So, I am dedicating this page to reasons as to why you should ONLY buy products which are 100% local control only, with no cloud dependency, and no proprietary hub.
A quick post going over the best options for taking advantage of home assistant's energy monitoring features.
To note- you don't have to use home assistant with these products. But, these products were specifically chosen due to some level of integration with home assistant.
