@scalz: Once the PCB's are available, I'll order some here (as you mentioned you might earn a bit). I have once ESp32 RFM95/LoRa GW already which works, but I'll switch to your HALO GW once you provide the PCB's, the code and the 3D Print files.

@gohan - Dell R710 over here, brought pretty cheaply in the UK tbh. I have a few things running on it as I'm Microsoft trained and certified so i enjoy messing with that kind of stuff. I was once in that field and attempted to get some work but nothing ever came from it (i got sick of hearing "Sorry, you don't have sufficient work experience") so I've ended up back in University studying mechatronical engineering Anyway, that is another topic for discussion, you're welcome to message me anytime for a chat, would be nice

The send-function is used to send updates to the controller, in your case the physical-button-switch-change. Doing the send, does not control anything on the node itself.

Qu3Uk, I did get a chance to test with a Fitbit recently. It technically worked, but not all that well. The thing is, the Fitbit only advertises every 2 seconds so latency is a bit high. But worse, its apps really want to be connected to it often to sync; and whenever it's connected, it stops advertising and the detector then can't pick it up. TommySharp, At this point I don't plan to modify the board much but having it read environmental sensors would be a cool feature! For that, would be nice to make little beacons that read sensors and advertise/broadcast the readings every few seconds. Then they could be very low-power, run on coin-cells for months, and could be placed anywhere instead of needing it to be hooked up to USB power like the main board is. Like these: https://sen.se/peanuts/ I'm curious if it could read them. As for enclosures, I know. I would love to have some nice ones but at this point I'm making too many boards to 3D print enclosures, but too few to afford injection-molding tooling to make a custom case.

@epierre said: I had the contact with this seller, but an international money transfer was needed and is expensive... yeah, they also have a minimum order quantity and ship with DHL only, so you have to pay import taxes to EU so it only makes sense if you order a big quantitiy and then try to resell it somehow all in all a hobby that at least has some return on investment, compared to other ones i had :)) You're courageous th have gone on kickstarter, from memory seeedstudio nearly went down because of an error on a crowdfunding project and had to produce and ship (the more expensive par of it) a remlacement for the first batches... ahh .. i didnt know this about them... and in their scale - i can undertand it happened to me as well but in my scale it was rather a paid lesson :))))

@Yveaux I have 34 of 80k RAM used for this sketch, so 128 bytes looks like "a bit more". You can not use progmem with ESP and mysensors now because PSTR redefined as PSTR(x) (x) so all strings are really in RAM

Actually, it's not 100% MySensors-related, but I have a working setup consisting of iBeacon (either HM10-based or PI-based) and Beecon app. When Beecon senses the iBeacon it can trigger various actions, eg make http requests or call IFTTT recipes

a spark core wouldnbe the best in this case
