Energy Meter in FTB Evolution 2

Same as in the All the Mods 11 0.8.0-beta guide

Energy Meter adds one simple block that measures how fast energy moves through your setup. It has a screen on its front that always shows the current rate, so you can check a machine line or cable run at a glance.^[1][2]

This pack ships version 26.1.2-0.5.0 of the NeoForge build. It is a complete rewrite and not an official update or port of the older Energy Meters mod, though it credits that mod's original author for the idea.^[1][3]

How the block works

The meter acts like a cable. Incoming energy requests are forwarded to its outputs, and the values of those requests are stored and used at a configurable interval to calculate the flow rate.^[2]

The display on the front can be rotated in any direction, including up and down. Because the front is used for the screen, only the other five sides can be set as input or output. In the interface you can set each side as an input, an output, or disabled.^[2][4]

What you can configure

• A graph view in the interface shows the last 10 intervals, and you can pause it.^[2]
• Transfer mode: Split (the default) shares incoming energy evenly across outputs. Transfer lets you give outputs priorities. Consume deletes incoming energy, which is handy for testing setups.^[4]
• Measuring mode: Instant (the default) only uses the current interval. Smoothed also factors in the previous interval, which calms sudden spikes.^[4]
• You can change the measurement interval and the calculation mode, and the interface also offers a transfer limit setting.^[2][4]

Same as in the All the Mods 11 0.8.0-beta guide

Energy Meter is a small mod with one job: it measures how fast energy flows through a line. The block works like a cable, so incoming energy requests are simply passed on to the outputs while the meter records them and works out the flow rate.^[1][2]

Step 1: craft the Energy Meter

Everything starts with Energy Meter. Here is the exact recipe from this pack.^[5]

Setting up your first meter

1. Place the Energy Meter in your energy line. The front of the block holds the digital display, so only the other five sides can be set as input or output.^[2]
2. Interact with the block to open its interface. The left panel is always visible and shows the current flow rate, the total measured energy and the status.^[4]
3. Use the I/O grid to set each side as an input, an output, or disabled. Left-click and right-click change a side, and you can reset a single side or all sides at once.^[4]
4. Check the status. Disconnected means the settings for the selected mode are incomplete, usually a missing input or output. Idle means everything is set up and the meter is waiting for energy to pass through.^[4]

Good to know early

• The default transfer mode is Split, which divides incoming energy evenly across all outputs. If one output accepts less than its share, the rest goes to the other outputs.^[4]
• The default measuring mode is Instant, which only looks at the current interval. Smoothed also factors in the previous interval, which gives a smoother graph with fewer spikes.^[4]
• The graph view shows the last 10 intervals, and you can pause it.^[2]
• Consume mode deletes all incoming energy instead of forwarding it. It is meant for testing setups, such as seeing how much energy can enter through your inputs.^[4]

The Energy Meter from Energy Meter works like a cable. Incoming energy requests are simply forwarded to the outputs, while the values of those requests are stored and used at a configurable interval to calculate the flow rate.^[7]

Sides, display and graph

The front of the meter shows the current rate on a digital display, and you can rotate that display in any direction, including up and down. Because the front is taken by the display, only the other five sides can be set up as input or output.^[7]

You set the sides in the I/O grid on the left of the interface. Each side can be an input, an output, or disabled for energy requests. Use left-click or right-click to change a side, and you can reset a single side instantly or reset all sides at once. Which options a side offers depends on the selected transfer mode.^[8]

The graph view shows the measurements of the last 10 intervals, and you can pause it. The global panel also holds the current flow rate and the total energy measured. The Reset Total button sets that total back to zero, and it can't be undone.^[7][8][9]

Status

The status shows the meter's current state, and it updates whenever a setting or state changes that could affect it, such as the flow rate, neighboring blocks, or your input and output setup. These are the states you will see:^[8]

• Disconnected: the required settings for the currently selected mode have not been configured. In most cases an input or output is missing.^[8]
• Idle: all settings are currently configured correctly and the meter is waiting to transfer energy.^[8]
• A third status, which depends on the selected transfer mode, indicates that the meter is currently processing requests and operating correctly.^[8]

Transfer modes

The currently selected transfer mode determines how requests arriving on sides configured as inputs are forwarded to the output sides. The default is Split.^[8]

• Split: while this mode is selected, incoming energy is distributed evenly across all outputs. If one output accepts less than its share, the leftover goes to the other outputs, so the split is not forced. If there are more outputs than available energy, the remainder goes to a randomly selected output.^[8]
• Transfer: this changes the I/O grid so you can assign priorities to outputs. Higher priorities get energy first, and lower ones only receive what the higher ones cannot accept.^[8]
• Consume: made for testing setups. It permanently deletes all incoming energy and disallows outputs in the I/O grid. It is handy for measuring how much energy can enter through all inputs when the outputs would normally limit the flow.^[8]

Measuring modes

• Instant (default): when this mode is selected, only the values stored during the current interval count, and previous intervals are ignored. Use it when you need exact values.^[8]
• Smoothed: when this mode is selected, the previous interval is factored into the flow rate. You get a smoother graph with less impact from sudden spikes, which suits watching average behavior over longer periods.^[8]

Settings fields

The Configuration tab has text fields for values such as the transfer limit, which defines how much energy the meter can transfer per tick (1 second = 20 ticks). A field shows the current value and does not update while you type. Press the button beside it or hit Enter to apply your change. An invalid entry turns the box red and can't be applied.^[8]

The fields also accept maths: addition, subtraction, multiplication, division, exponentiation and parentheses. A small popup shows the result so you can apply it. Every value is an integer, so results are rounded to the nearest whole number.^[8]

The values for the current measurements update once per configured interval. Reaching the tolerance is the only exception.^[8]

Pack config

The pack leaves meter.default_interval at 5, the same as the mod default, and it accepts values from 5 to 200. That is the starting value, and you can change it for each meter in the GUI.^[10]

The pack sets meter.allow_meter_connections to false, so meters can't connect to each other. The config notes that allowing it can cause performance issues and let players abuse meters as infinite cables.^[10]

The External Monitor has size limits in the config. monitor.max_width is 32 and monitor.max_height is 18. Both match the mod defaults and can be set anywhere from 1 to 128.^[9][10]

What the meter does

The Energy Meter works like a cable: incoming energy requests are forwarded to its outputs. It records those requests and uses them at a configurable interval to calculate the flow rate. The rate shows on a digital display on the front of the block. Because the front is used for that display, only the other five sides can be set as inputs or outputs.^[2]

The interface also has a graph view of the last 10 intervals, which you can pause. You can change the measurement method, the measurement interval and the calculation mode.^[2]

Getting started

1. Place the block and interact with it to open its interface.^[4]
2. Use the I/O grid on the left panel to set each side as an input, an output, or disabled. Left-click and right-click both configure a side.^[4]
3. The right panel depends on the currently selected tab, so open the Configuration tab to choose the transfer mode and the measuring mode.^[4]
4. Check the status. Disconnected means the settings for the current mode are incomplete, usually because an input or output is missing. Idle means everything is set up and the meter is waiting to transfer energy.^[4]

Modes to know

The in-game guide lists Split as the default transfer mode. It divides incoming energy evenly across the outputs. Transfer mode lets you give outputs priorities, so higher-priority outputs are filled first. Consume mode deletes all incoming energy instead of forwarding it, so it is meant for testing setups.^[4]

For measuring, the guide lists Instant as the default. It only uses the current interval, which is handy when you want exact values. Smoothed also factors in the previous interval, which flattens out sudden spikes in the graph.^[4]

Same as in the FTB StoneBlock 4 1.21.0 guide

Energy Meter has only a handful of options in its common config, and they're easy to read. Here's how the pack sets each one.^[12]

Meter connections

meter.allow_meter_connections is set to false in the pack, so meters can't connect to each other. The config comment warns that allowing connections can cause performance issues and lets players abuse meters as infinite cables, so the pack is playing it safe here.^[12]

Unverified The sources don't show the mod's own default for meter connections, so we can't confirm whether the pack changed this value.

Default interval

meter.default_interval is 5 in the pack, which matches the mod default. The allowed range is 5 to 200. According to the config comment, this sets the default meter interval and zero tolerance, and you can change both per meter in the GUI.^[12]

Monitor size

• monitor.max_height is 18 in the pack, the same as the mod default. The allowed range is 1 to 128.^[12]
• monitor.max_width is 32 in the pack, also the same as the mod default. The allowed range is 1 to 128.^[12]

FTB Evolution 2 1.1.0 ships Energy Meter version 26.1.2-0.5.0. The sources here show one mod-side change worth knowing about, and it is the one this pack version is built on.^[13]

• 26.1.2-0.5.0: the mod was ported to 26.1.2. This is the version that FTB Evolution 2 1.1.0 includes.^[13][14]
• Energy Meter was already in the pack by FTB Evolution 2 1.0.2 or earlier, so it is not a new addition in 1.1.0.^[13]

Unverified The pack changelogs for this mod are not shown in the sources here, so any pack-level changes to Energy Meter between releases are unverified.
