Turned a LILYGO T-Display into a little Claude usage meter,

A few days ago I ran into alessandro-001's ESP32-claude-usage-display and really liked the idea: a tiny always-on screen that shows how much of your Claude limits you've burned through. I forked it, then ended up rewriting a big chunk, so figured I'd share where it landed.

I'm running it on a LILYGO T-Display S3 (the small 1.9" color one).

The part of the original that bugged me was the auth. It grabs your usage by pasting your claude.ai browser session cookie straight onto the device. That cookie lives in the ESP32's flash and expires/rotates, so you're re-pasting it every so often, and I wasn't thrilled about a live session token sitting on a microcontroller on my wifi.

So I moved the whole credential side off the device. There's now a small Python proxy that runs as a Home Assistant add-on. It talks to Anthropic's OAuth usage endpoint (same data Claude Code's /usage shows), does the token refresh itself, caches the result, and hands the ESP32 a stripped-down JSON with just the percentages and reset times. The Claude token never leaves my HA box; the display only ever talks to the proxy. When I'm not home I expose the proxy through Tailscale Funnel, so it's a single URL that works everywhere with a proper cert.

Couple of other things I added:

  • Multiple wifi networks (up to 4). I wanted to actually carry it to the office, so it connects to whichever saved network is in range and switches on its own when I move.
  • Redid the UI. Dropped the old number-plus-bar for a ring gauge with the percentage in the middle (color-coded by how close I am to the cap), a countdown to the next 5h reset, and the 7-day reset as an actual local date/time.

Repo and a v1.0 release with a prebuilt binary: https://github.com/AussieCH/ESP32-claude-usage-display

Fair warning that's also in the readme: polling that usage endpoint from a third-party thing is a bit of a ToS grey area, so treat it as a "your own account, at your own risk" project.

Happy to answer anything. Also fully prepared to be told I overengineered the wifi part.

My cousin lost his career to a knee injury. We just need CHF 600 to help him rebuild his strength.

Hi everyone,

I'll keep this honest and simple. Tommy is my cousin. He's in his early 50s (born in 1972) and has worked hard his whole life — over 20 years as a painter on construction sites, most of it at the same company. Physical work was his everyday, and he was proud of it.

About two years ago he injured his knee at work, and he still hasn't recovered from it. He can't do his old trade anymore, so he's now retraining for a completely new career and is currently doing an internship to make that happen — a brave fresh start in his 50s.

The downside of two years mostly stuck at home is that he's lost a lot of the strength and stamina he used to have. He feels it every single day in the internship now, and it's wearing him down. He wants to do something about it by training regularly at the gym — for his health, to keep up at work, and to finish his retraining. I'm at the gym three times a week anyway, so we'd train together and I'd help keep him on track.

The problem is money. His income dropped during the retraining, so a gym membership just isn't affordable for him right now. His health insurance covers part of the cost. For the annual membership he's still about CHF 900 short. I'm chipping in CHF 300 myself, so we're trying to raise the remaining CHF 600.

That's the whole ask, CHF 600. Anything beyond that goes straight toward his recovery and training. Even just sharing the post helps a lot.

A smart home panel for your entrance that even the cat sitter can use

Designed a wall mount for a smart home touch panel that hides a 230V PSU and NFC reader inside the enclosure. Printed in PLA, held together with M3 heat-set inserts. More details and files in the original post! https://www.reddit.com/r/homeassistant/comments/1txjepl/

A smart home panel for your entrance that even the cat sitter can use

Built an entrance panel that lets guests control the home with NFC cards – no app, no login, no explanation needed. Touch display + hidden NFC reader + mains PSU, all in one 3D printed wall mount. Full write-up here: https://www.reddit.com/r/homeassistant/comments/1txjepl/

A smart home panel for your entrance that even the cat sitter can use

Wall Mount for Guition ESP32-S3 4848S040 – A smart home panel for your entrance that even the cat sitter can use

Hey everyone! Long-time lurker, first-time poster here – wanted to share a little project that started with a very specific frustration: every time someone else needs access to our flat – the cat sitter, a family member, an Airbnb guest – I'd end up writing a two-page instruction manual for the smart home. Not ideal.

The solution I landed on is a wall-mounted panel right at the entrance, combining a touch display with a hidden NFC reader. Hand someone a card, they tap it on the way in, and the right things just happen – lights turn on, the heating adjusts, whatever scene you've set up in Home Assistant. No app, no login, no explanation needed.

The hardware side of things

The enclosure is a custom-designed PLA print that fits the Guition ESP32-S3 4848S040 touch display and hides everything behind the wall plate. The bottom compartment houses a Mean Well IRM-05-5 AC/DC power supply – mains voltage in, clean 5V/1A out. No power brick, no USB cable creeping down the wall. The display connects via a 4-pin MX1.25 connector (PIN1 = GND, PIN4 = +5V), and the ATOM Lite for the NFC reader gets its power from a second 4-pin socket in the same compartment.

The NFC reader sits behind the top panel, completely invisible from the outside but close enough to scan reliably. It's based on the excellent "No Soldering DIY NFC TagReader" project – if you haven't seen it, definitely worth a look. The idea is simple: you hand out pre-programmed NFC cards to whoever needs them. The cat sitter gets a "cat sitter card" that triggers exactly the automations she needs – nothing more, nothing less. No fumbling with apps, no accidentally turning off the heating.

Software

The display runs ESPControl (an ESPHome-based project by jtenniswood) paired with Home Assistant. Fully local, no cloud dependency, and fast enough that it actually feels responsive to the touch. The NFC side is handled entirely within Home Assistant automations – each card has its own tag ID and triggers whatever scene you've assigned to it.

Assembly

The enclosure prints in PLA and goes together with 4× M3 heat-set inserts and 4× M3×8 hex screws. Solid wall mount, no glue, no friction-fit guesswork.

Happy to answer questions in the comments – and curious whether anyone else has gone down the "NFC for guests" rabbit hole!

Quick safety note: this build involves mains voltage (230V AC). If you're not comfortable working with line voltage, please have a qualified electrician handle the wiring.

How to activate this entity?

I have a SwitchBot robot vacume with HA integration. The device has three entities. Battery, Bluetooth signal and the Robot it self K11+Vacuum 784C. If I click the entity I get this card with two possible actions to chose:

How can I trigger this, as exampe in a automation or on a device/dashboard through a button?
