I’ve been playing around with my Nextion and a Particle Photon for a while. The idea is to pull data from a variety of services and have it available on a display by the front door – things like the weather, the outside temperature (from my Netatmo), and the next 3 trains to Seven Sisters from our station. Living, as we do, at the end of the Enfield Town branch line, it can be a bit hit and miss as to whether or not you make the train, or if it’s even running.
Anyway, I got the first part of this working. I regularly poll the National Rail SOAP API, parsing the content in to a simple minified JSON format using a Power App. Took me a while.
Then I discovered that someone has written a JSON proxy for the LDBWS. I’ll try that next.
