Seen as I can't seem to located place to purchase this at a reasonable price:

(
).

I'm currently building one, the specs so far are:

1) It can controller 8 outputs at 25amps (300w) per output (limited by connector I'm using https://deutschconnectorstore.com/product-category/multi-pin-connectors/dtp-connectors/, outputs can be bound together to controller larger loads. Max will be 60amps (720w) on all output. Tempted to switch them to use these connectors (https://www.amazon.co.uk/Waterproof-Electrical-Connectors-Socket-Marine/dp/B01DVQ2ANO) but that would limit each channel to 15amps. Each output is fused using a standard automotive fuse.
2) It's using mosfets so it can be used to dim LEDs light bars etc
3) It's bluetooth so you don't need to run anywheres into the cab
4) I'm thinking about building a lcd touch screen controller if you don't want to use your phone.
5) I can have it to automatically turn of lights on engine off etc

My questions is anyone seen another product like this for cheaper before I send off for the pcb making. Also anyone any comments about this just making a proof of concept at the moment.

Sounds interesting and similar to something I’ve been considering. I like the idea of wired but with a simplified bus type idea like DMX or RS422. Trouble is I can’t find many transmitters to take switching inputs. I have seen and bought two of these though. Wifi linked.

They don’t really do what I want though as it’s all momentary or all latching.

As it will be a ESP32 controller I can easily program it to accept either, just ordered some rs485 controllers for it to be hardwire between the LCD screen and the controller, as it only needs two wires and can run up to 400 meters.
Interested to see how they control the current with that thing you’ve ordered I’m guessing relays so dimming (PWM) is out of the questions.

I like the idea but it seems a lot of work to achieve wireless functionality.

Something like this does a lot of what you want but of course with wires. https://www.aliexpress.com/i/33030953590.html

My other thought it wouldn't the led controllers in the light bar etc also need to support being dimmable? Just dropping the voltage/current may not work in a lot of cases?

Led's aren't like normal bulbs so you can dim / over current them a little but there are very fine limits.

The main reason for doing this, is having this entire thing sat on the roof rack, linked to the light bar and the 3/4 other lights, rear/side/in tent etc and not have to worry about having to get a control cable into the cab.

As it's BLE you can control it from your phone when around the campfire, in the roof tent etc, the microcontroller / hardware is working just wanted feature ideas and make sure there wasn't something off the shelve that did this before I sent off to get some PCBS printed and get working on the mobile APP.
