Agh, thank you! I'm such a new user, I had no idea domoticz could see gpio directly. You have given me new research avenue, I really appreciate the replies.

Ah crikey, you're right there. Thanks @mfalkvidd, time to dust off the soldering iron.

Cheers

Hi, old thread but I hope a question not too far off the mark. I'm using Easy PCB nodes and looking to use OTA on the reverse side. I'm having some issues finding a source in Australia for the SPI chip mentioned, I am seeing this one very easily available. From the data sheet on the page, it appears to be pretty much the same, just the lower end of the acceptable voltage is up to 2.6V. Any thoughts welcome if you can see if it would/wouldn't work, my tech knowledge is limited on this sort of thing.

@sundberg84 you raise an obvious point about upper voltage that I'd overlooked to to be honest. I'll make a 3.3v node up to test when the chips arrive to test. If it works, perhaps try to use on 5v node with a shifter. Will report back if they work or not. I see also in the code now, reference to using i2c eeproms. Plenty of options to try. Thanks
