Home automation and light switch controllers components


Hi Jon and all,
I am about to order all spare parts to assemble light switch and automation controller which Jon reviewed in his amazing videos.
As he is probably very busy with his projects and has thousands of emails, it is not very easy to ask him directly, does anybody know:

  • What kind of shield is Jon using in his Home Automation controller today? In his latest video it is different from what he was using a year ago. He mentioned that he is not using 8-Channel Relay Driver Shield anymore, what might be the reason for this? There might be something new, which does not require soldering out pull-up resistors.
  • For the light switch controller, I/O Breakout To RJ45 are out of stock, are there anything to replace? Or if Jon reading this - do you expect them in stock?

Thank you.
