Hi all, not yet an active project as such but I am playing with the following idea.
Many times (but not frequent) I want to be able to manually test trailer lighting.
From the “vehicle side” or “trailer” side. There are some testers available and some expensive kits also. I want it for the so called 13 pins (jaeger) and 7 pins connectors.
Let me sum up the idea:
-
complete package in a “makpac”
-
wood board covering all electronics with some lights and (test) buttons and the plug inserts:
-
2 cables to be plugged into vehicle.
-
the electronics selected so far:
-
12v Lights (link)
-
Battery (link)
-
7 pins socket (link)
-
13 pins socket (link)
-
Battery charger (link)
-
Relayboard- Kinkony kc868-e16t:
KinCony KC868-E16T | devices.esphome.io
I have not yet created a proto-type of ESPhome config. Still in “thinking” phase.
The requirements:
- Can run independent and standalone without a connected vehicle. By using the battery (optionally with charger connected) to test each pin individually and some with a “scene” (in esphome).
- Can be connected to the vehicle and test all pins.
- Testing can be viewed by lights that are mounted in the wood board “in” the printed above drawing (parallel to the pins).
- 7 pins connector is just a subset of the 13 pins
- So each pin/light has a button to be manually activated and additionally extra buttons to for scenes. And maybe enable/disable toggle.
- ESP has a wifi network when not connected to HA to show the in and outputs via the browser screen.
I am asking in this topic for any additions/feedback/ ideas before I start building and get to the point "hey this could have been done more easy/better.
Thanks!
