Battery Monitor 2.0 — Setup Guide

INSTALL VIA HUBITAT PACKAGE MANAGER (HPM)

1. Apps → Hubitat Package Manager → Install

2. Search by Keywords → "Battery Monitor 2.0"

3. Select the package → Next → Install

SETUP

Step 1 — Select Devices

Open the app and select all battery devices you want to monitor.

Click Done before viewing any reports — this is required on first setup.

Step 2 — Set Scan Interval

Controls how often the app reads battery levels to build drain history.

• Hourly — most accurate, fastest to establish health ratings

• Every 3 Hours — balanced (default)

• Every 6 Hours — lowest overhead

Step 3 — Notifications (Optional)

Toggle on Enable Notifications to reveal all notification settings including

frequency, time, notification devices, and which battery groups to include.

Step 4 — Battery Catalog (Optional)

Assign a battery type and quantity to each device (e.g. CR2032 x1, AA x2).

Appears in the Summary table and in Poor device alerts.

This is a one-time setup — tap Done to save.

Step 5 — Done

Click Done to save. The app will begin collecting data immediately.

Health ratings show Pending for the first 5 days and 5 samples — this is normal.

TIPS

• Use Manual Battery Replacement after swapping a battery to reset history immediately

• Use Force Scan Now on the Summary or Trends page to read all devices on demand

• Set Scan Interval to Hourly to build health ratings faster on slow-reporting devices

• Health ratings and Trends use the same thresholds — they will always agree

Tried this last night and again this morning, and get this screen every time I try to access your GitHub.

Try the updated link in the OP.

This list of features is pretty much exactly what I've been wanting for a while and was even considering creating my own app for it. Are you planning on putting it in HPM? I just see the original one you mention.

13

I have not gotten that far. I updated it, tested, and was like, why not share. LOL

Not even sure of the process for HPM.

I have a few others i may create and test as well.
1- Intellicenter Pool Control
2- Open to suggestions

There is a new HPM helper publishing app just released I believe.
May make things easier?

15

Bingo! Raw code showed up. :slight_smile:

I would not call myself a developer. I only wanted to share this based on my needs.
I barely have enough time to figure this first part out.

@JdThomas24

Can you add a button for a Current Report to display on screen?

Display on what?

There is a plan to create a dashboard tile adder but i have not had time to test that yet.

On screen, similar to how Device Activity check does

The original Battery Monitor app shows the current report in the app screen... And there is a "Refresh" button to update the report shown.

Your app was unable to find any battery devices on my hub using the auto detect option - it reported "Battery Report: No battery devices found." I turned off the auto detect and chose the devices manually.

The battery report is coming as one message per device, which is very difficult to read/use (I'm sending reporting to Pushover). It's just a mass of too many messages. :slight_smile: If you can you adjust the reporting to send one report, or at least one report per battery level category that will make this app's report usable.

Good start.

I was seeing this when requesting GitHub docs from the tile builder site too. Once I logged in they went away. I think it's a github change trying to get people to log in.

23

Yeah, I did sign in when that happened but it didn't help. :man_shrugging:

24

Huh. Maybe GitHub is starting to institute rate limits. That would be terrible.

I guess the workaround would be to download the docs when you get access. I'll probably do that for tile builder since there is A LOT of documentation needed to use it

25

Yeah, might be. I've never seen any message like that before. I also barely use GitHub, don't have any projects myself and very infrequently visit to download some raw code. Weird.
