I bought a great relay board, with 16 relays, which is enough for all my needs. I would like to have simple and convenient integration.

It seems XL9535 is logically the same chip as PCA9535/TCA9535

Hi @flyte @mschlenstedt @BenjiU

I'd like to work on support of XL9535/PCA9535/TCA9535 chip and prepare PR. Could you please point me how to add a new device?

It seems there is no existing python "driver" published in pip. Could low level code be placed in this repo or should I make separate package?

Some kind of nodejs driver https://github.com/isky04/node-red-contrib-xl9535

I recently started to add some sensors to MQTTIO. As far as I know there's no developer documentation. I looked at the existing modules, take one which is similar to the one I would like to add and started and tested on a life system.

You'll finde the code here:
