MCP23017 - MQTT subscribe - MCP23017

[Stejin]

Currently flashed the ESP_Easy_mega-20200204_normal_ESP8266_4M1M.bin

What I want to accomplish:
ESP2688 (NodeMCU) + Multiple MCP23017 (Up to 8x16 = 128 GPIO) + RelayBoard (Up to 128 Relay's)
Using these to trigger relays or use them as inputs.

I did what is described here:
viewtopic.php?t=6712

That lead to Topics in my ioBroker + MQTT Broker to be displayed and getting values based on the values on the GPIO Pins on the MCP23017.

Is there a way with rules to subscribe (and create) all 16+ topics from ESPEasy in ioBroker?

What I also noticed that the "/cmd" Endpoint/Topic is not present in ioBroker. (so i can't test the command feature, with which I could accomplish my goal, but it would be nice to have "fixed" topics/ maybe even the same as the currently created ones)

If you define an MQTT controller and assign your devices to that controller, the values of your devices will "automatically" been sent. You do not need a cmd or publish at all.

I added the device "MCP23017" like this: https://www.letscontrolit.com/wiki/inde ... e=MCP23017

As far as I noticed this only supports one Port per device? With 12 devices max that is less then the MCP23017 supports and much less I want to accomplish.
Furthermore it seems this adapter only works one way? ESP -> MQTT but not the other way around.
