if TRMNL is too expensive, get a cheaper 3rd party option then: 1. flash our* OSS firmware (https://github.com/usetrmnl/trmnl-firmware) 2. spin up an OSS server client (https://docs.trmnl.com/go/diy/byos#implementations) 3. install the Home Assistant plugin (https://github.com/usetrmnl/trmnl-home-assistant) no need to write any code or give TRMNL a penny, while still benefiting from a few years of deep dev in this area. * i'm on the team
In HomeOS – A self-hosted family dashboard for a kitchen touchscreen
ronakjain90·Jun 5, 2025
Your product looks so good, congratulations on your launch. Have you considered making a standalone devices with just sensors (think data only mode) and letting the users hook up their data on any eink dashboard of their choice. Below are some of the example of community created Air Quality dashboards[1] installable on any e-ink hardware[2]. [1] https://usetrmnl.com/recipes/62233, https://usetrmnl.com/recipes/23306 [2] https://github.com/usetrmnl/firmware/ Disclosure: I work at TRMNL.

I think you should also checkout TRMNL. Being engineers ourself security/privacy is of atmost concern, and we follow a similar architecture mentioned above. You could create a private plugin and send in data in the form of REST APIs[1]. You could also use your own webserver by hacking the firmware[2] [1]-https://help.usetrmnl.com/en/articles/9510536-private-plugin...

In MomBoard: E-ink display for a parent with amnesia
krinchan·Nov 14, 2024
They seem to have the api base url hardcoded in their firmware[1]. The repo seems to have pretty clear instructions for compiling and flashing modified firmware. From there, it's just a matter of writing a decent server to implement the calls documented in BYOD/S[2] and Private API.[3] [1]: https://github.com/usetrmnl/firmware/blob/e3db8c37990c2333ec... [2]: https://docs.usetrmnl.com/go/diy/byod-s [3]: https://docs.usetrmnl.com/go/private-api/introduction
