This chart tells the tale:

What to do with all that speed? Become a software defined radio, maybe? Or perhaps run the entire development toolchain on the device itself?

@alowhum good point. Maybe not learning, but inference could be very useful.

I finished gateway for my attic - What did you build today (Pictures) ?: As this will be under roof but without any isolation I try to put small silica gel bag (I collect them from other electronics packaging) inside and will see. I think it should be suitable. I am thinking of adding temperature and humidity sensor... that could also help me show how much humidity is around the year actually. I might use the resin / epoxy stuff for some watering projects

@robert022 I suggest taking a trip to the local library and looking at books there or taking them home to study. A good bookshop might also be an option to look through books that you like the style of. Check your local college to see if there are any evening courses that might help and I suggest going to talk to the person teaching the course and explaining what you want before signing up. They are usually very helpful and can give better guidance. Internet is also a good place to learn, it is also a big place too so finding exactly what you are looking for may take a little time. Finally are there any clubs or 'maker' groups in your area? If so again talk to them before joining to see if it is going to meet your requirements.

@BearWithBeard had the same issues when I tried to recompile existing sketch and dug out the above libraries. My problem is that I then get a compile error "'atsha204Class' does not name a type; did you mean 'atsha204_read'?" at this line "atsha204Class sha204(sha204Pin);" Was just going to update working sketch to new mysensors library - but I guess not.

There is already a LoRa library available for both Arduino Board and STM32 Bluepill Board. Using the simple library, the LoRa Module SX1278 is easily transmitting and receiving data packets. You can check one of the best example here: (https://how2electronics.com/interfacing-lora-sx1278-stm32-sender-receiver/)

Yes in the mean time I understand that MySensor have all the personalized ask/answer structure. But I still study cause I like much this type of home network. Anyway maybe there can be a personalized gateway part only for the incompatible sensors. I'll try to study it when I'll be more "old" in this Thanks a lot for the answer Denis

@andrezibaia - my understanding that lower frequencies easier penetrate walls, and im also suspecting the Nrf24l01+ (2.4Ghz) wont work. Im using RFM69 for my outdoor nodes, and its working well penetrating the house walls - but in your case you have multiple floors (thicker than walls?)... If you have the radios, I would try them.

As a postscript to my own question should someone be looking at similar later, in practice the sensors were found to work perfectly well at 3v3. Described as 5v working, 0.5-4.5v signal range, the effect is pro-rata at 3v3 in terms of voltage but the ADC output is identical for VCC scaling - viz, ZERO pressure is 10% of 1024 the range is 80%

Unless you make progress on this yourself you need to do the following to get more help. Post links to the items you are trying to use. Post links to the libraries you are using to achieve this. Post your code. Without the above it's all a shot in the dark.
