RE: RFM69(H)W Arduino Mini Pro Shield to offer
Hi, I'm interested in getting some of those. They are right on time for some new developments I'd like to run over the summer. Final number depending on total number of interested colleagues.
Many thanks for your generosity but I'm willing to pay for them if you want.
Great contribution, many thanks!!!
RE: 💬 Soil Moisture Sensor
@รอเร-อ I have resistive sensors (YL-69 type) both indoors and outdoors. Both have been working correctly for months now. I'm using a direct-reverse polarization sketch to minimize corrosion and it seems to work well. What I found to be very important in outdoors sensors is the isolation of the connector between the probe and the cable; if rain water or watering stays into there, they tend to corrode and their resistance increases, therefore fooling the sensor into thinking that the soil is drier than it really is. I have a couple of capacitive sensors somewhere but haven't felt the need to try them since the resistive ones are working well.
RE: Z-wave question
@manutremo I do mention Domiticz several times
OMG either I read too fast or my eyes are going really bad...
Either way - the response to your last question is no, devices can't be grouped in the Devices page... this is probably one of the most requested features but... just not there yet.
For the first question - the quick answer is those devices are normal and you may just ignore them; some of them are there as placeholders for future development. For a more detailed answer, just do a search and you should find the answer without having to interface with anyone... I'd send a link to the response but I don't have it readily available.
RE: Z-wave question
@raptorjr You don't mention it but I guess you are using Domoticz. I would suggest you ask the same questions on their forum; the first and third questions are answered there.
Regarding a zwave water proof and cold proff switch, the "normal" ones (fibaro, neo coolcam, aeolabs, etc) seem to work well in cold weather, and it all depends on at which temp their battery stops providing enough juice. Regarding water proof, I don't recall having seen any, but a search on ebay or aliexpress might reveal some. As a last resort, you can always wrap them on kitchen plastic film; I do that with some of my mysensors equipment and it works very well.
RE: Serial.print and battery powered pro mini
@peerv I don't use one of those "red" adapters but mine does the same and it seems to be no problem. Just test it, at worst case there might be some communication problem but that's all and I don't think it should even actually happen.
RE: 💬 Connecting the Radio
I would not expect anyone to put or take responsability on anyone for a piece of advice. I think we are here to help each other by sharing information and our own experiences.
The full picture should be more than clear at this point for anyone reading this and other threads, but I will clarify once more. Best practice is using the rfm69 family with a logic level converter when connected with a 5v arduino, given that as of today the manufacturer's datasheet is not 100% clear on this area. From a problem solving perspective, keep in mind, however, that should a converter not be in place for any reason, the setup might or might not work, so if it doesn't don't discard it as a cause but don't take it for granted at 100%. And even if it works, do plan for adding a converter.
RE: 💬 Connecting the Radio
They've been working for more than 6 months now as part of a test run and are not yet fried.
There is other people around reporting the same with at least the rfm69HW. I remember someone stating that the new models are more robust in this regard than older models, in spite of the manufacturer not yet stating 5v tolerance in the data pins.
In fact the datasheet never mentions 5v intolerance, and it does never actually mention a max voltage for the data pins, only for Vdd.
It seems like the board does something with the voltages in the data pins anyways, since if it was using the definitions of the logic levels (as a percent of Vdd) as they appear in the datasheet, it should not be able to communicate at all with a 5v arduino when powered at 3.3v and no logic level shifter on the data pins - but it does.
This doesn't mean this is good practice, directions in the datasheet are there for some reason and my nodes will eventually get a logic level shifter when they finally go into their final case. But reality is it seems at least RFM69HW can tolerate 5v for months without being fried.
