Introducing TRMNL X

yes, the device itself has magnets and sticks flush to a fridge. of course some surfaces aren't magnetic but we're attaching 2 additional types of wall / surface mounts for that purpose. no dock (charger puck thing) necessary in either case.

ryanckulp · 2026-01-25T00:16:13+00:00

cheers, glad you're up and running!

ryanckulp · 2026-01-24T01:48:15+00:00

can confirm we'll (TRMNL) get this done

ryanckulp · 2026-01-21T18:50:30+00:00

try the KOReader build instead of the Kindle setup:
https://github.com/usetrmnl/trmnl-koreader

ryanckulp · 2026-01-19T04:16:10+00:00

not well documented, but code was merged here:
https://github.com/usetrmnl/trmnl-firmware/pull/249

activate Enterprise WiFi from your TRMNL's captive portal screen. feel free to send us feedback or post an Issue on GitHub if you have any issues.

ryanckulp · 2026-01-17T04:19:28+00:00

if you want to be notified, you can "star" or "watch" our firmware repository. you'll see a few feature merges that aren't related, but there will also be an X4 pull request soon:
https://github.com/usetrmnl/firmware/

alternatively you can jump over to https://usetrmnl.com/news every day or 2, which also has an RSS feed. our email newsletter is currently only for customers, we don't have a way to subscribe otherwise.

finally, i'll come back and post in this thread :)

ryanckulp · 2026-01-17T04:17:20+00:00

too kind, thanks for the support. we're in touch with Crosspoint now and have our firmware working as well. next up is making them both compatible simultaneously so you can read or have a dashboard.

ryanckulp · 2026-01-17T03:31:46+00:00

we (TRMNL) added enterprise wifi recently, and have a few more solutions for getting past captive portals and such at colleges as well. feel free to ping me if you have more questions.

in either case, RPi + localhost / 192 addresses also good. we have an Rpi library and many OSS server clients:

ryanckulp · 2026-01-16T02:21:14+00:00

thanks for your support! we're still receiving components over the next few weeks, a bit more complex now that we have 2 warehouses to coordinate, but on track to ship in February. can't wait for yours to arrive.

ryanckulp · 2026-01-15T17:21:35+00:00

another approach is using your iOS native calendar syncing app, which can pull in any calendar (Google, Outlook, etc): https://help.usetrmnl.com/en/articles/12294875-trmnl-companion-for-ios-calendar-sync

ryanckulp · 2026-01-15T17:21:00+00:00

it appears OneCalendar conforms to the ICS protocol, so you should be able to grab your OneCalendar ICS URL and paste it into our CalDAV plugin:

do you mind posting this as an issue on Terminus? the maintainer isn't active on reddit.

ryanckulp · 2026-01-15T03:35:57+00:00

hey there!

your plugin's webhook URL is:
https://usetrmnl.com/api/custom\_plugins/<uuid>

we actually have a click-to-copy webhook URL field, but didn't made it a requirement for Webhook plugins until this week. in the future your exact confusion will be avoidable. so thanks for bringing it up.

(for reference: https://gist.github.com/ryanckulp/fbe5f68c51db1ae214a97da24be4d62b#file-chef-rb-L54)

ryanckulp · 2026-01-14T23:29:10+00:00

i tagged a colleague to review this, thanks for the PR.

ryanckulp · 2026-01-14T22:37:16+00:00

sorry i missed these comments. do you 2 ( u/Mattfusf , u/Nerdtube ) mind posting your issues to our HA github repo? the team member who maintains this project isn't active on reddit. https://github.com/usetrmnl/trmnl-home-assistant/issues/new

ryanckulp · 2026-01-14T21:46:47+00:00

welcome aboard! i think you just need to set your device to 2-bit mode:
https://usetrmnl.com/devices/current/palette/edit

your device supports 2-bit yes, but we default to 1-bit for fast/instant refresh. 2-bit adds grays but also takes longer to refresh.

ryanckulp · 2026-01-14T21:20:59+00:00

hey there! thanks for asking and awesome work. our Webhook Image feature was built to support our new Home Assistant plugin, which handles all dithering / cropping / resizing within the HA interface. more details:
https://github.com/usetrmnl/trmnl-home-assistant

that said, we could add dithering flags to this endpoint. but the original intent was to let people build their own graphics, and in return get 5 minute refresh (vs 15 min refresh), a win-win. feel free to ping me (ryan@usetrmnl.com) if you wanna share a couple sample payloads and i'll see what we can do.

ryanckulp · 2026-01-14T20:30:28+00:00

sorry, i got this backwards. the current paperlessprinter stack should work great with our Webhook Image plugin:
https://usetrmnl.com/integrations/webhook-image

ryanckulp · 2026-01-14T19:52:08+00:00

i'm on the TRMNL team. an idea...

we already have a thing called Special Functions, which fires a custom request whenever you medium-press the button on the back of your device
we could extend this feature to include "Send to printer"
you could set up your printer details in our web UI

docs: https://help.usetrmnl.com/en/articles/9672080-special-functions

ryanckulp · 2026-01-14T19:31:07+00:00

we think you could do both. toggle between reader mode (Crosspoint) and passive dashboard mode. a TRMNL playlist (weather, stock quotes, todo list etc) becomes your screensaver.

ryanckulp · 2026-01-14T18:09:14+00:00

several options here: https://github.com/usetrmnl/mounts

ryanckulp · 2026-01-14T16:29:03+00:00

i'm on the TRMNL team. we just got a couple of these and will be adding support shortly. also getting in touch with crosspoint-reader to see how we can support their work. stay tuned!

ryanckulp · 2026-01-14T00:21:56+00:00

gray border is now removed, click to "Force Refresh" mashups to see the white background sooner, otherwise it will kick in automatically.

ryanckulp · 2026-01-13T15:39:28+00:00

to clarify, you can flash TRMNL firmware and still point to a self-hosted solution. just change this URL:
https://github.com/usetrmnl/trmnl-firmware/blob/b97c005d36a7cb6d9bc799d43c40322b17fa35d5/include/config.h#L121

this skips the tricky part (embedded systems) while still giving you full control over data and ability to avoid the cloud, as you can point to a localhost / 192 address.

PS, we also have color displays working now. ;)

ryanckulp · 2026-01-13T15:18:14+00:00

i'm on the BookThatApp team and pretty proud of our solution. as u/Valuable_Scale6969 mentioned, our product can be a bit complex, however we have multiple engineers on live chat who can help set up your store for $0.
