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

@evb said in Checking mechanical locked doors by a battery-based windows/door sensor node:

@p359 I have republished it and now I get the 'thing', no 404 anymore.
Can you try again?

@evb , you're a champion, thanks so much, appreciated.

@evb said in Checking mechanical locked doors by a battery-based windows/door sensor node:

You can find the design (open source FreeCAD) and STL files at: https://www.thingiverse.com/thing:4659402
The last months the thingiverse website has many problems, designs are not visible, 404 messages, etc.
Post a note if you don't find the 'thing'

Hi @evb, I'm seeing a 404, if you're able to link somewhere, would be interested to look at the files. No drama if not, cheers

Hi. I've found some old parts in a clear out, labelled 915Mhz RFM69. Before using them, I see online a mixture of info for Australia. This one is from Things Network which I'd hope is accurate:

"For AU915, we use Frequency Sub Band 2, also known as channels 8-15, or 916.8MHz through to 918.2MHz."

Anyway to achieve this in mysensors or might be over thinking this? Have read the api docs best I can and nothing jumps out, only network ID. Just to check. Cheers!

@ncollins 1.8.10 also. I'll try then 1.8.6 tonight. Cheers for the idea!

Hi. Are the steps in first post still valid please?

I'm trying without luck to get first nrf52 programmed. I get a weird error"Error resolving FQBN: missing" in Arduino IDE when I try to verify any basic sketch, even blink. Thanks for any thoughts

Not making too much headway with this. Chips arrived, soldered on the the reverse side of the easypcb. Not able to get any sign of the flash being seen. One odd thing, the physical solder pad for the flash chip, pin 6 on my boards isn't connected to sck of the arduino pin 13 at all, just a bare solder pad. I've bridged this with wire, still no luck. Hmmmm...! More experiments ahead, good fun!

Here's a random question, has anyone made or considered if possible even, an RFM69 radio version? I'm considering moving to RFM69 from NRF24 due to some range issues.. maybe.. Will need two gateways or something along those lines to keep using these fantastic nodes, have 3. Any thoughts back would be terrific, is there for example some show stopper I'm missing or just a matter of space and creative wiring!?
