I will answer myself after some testing done today:
How can I change network id for gateway (mysgw)?
It is possible to change MY_RFM69_NETWORKID for mysgw by exporting CPPFLAGS variable with the option set before running ./configure:
example:
export CPPFLAGS='-DMY_RFM69_NETWORKID="101"'
./configure --my-gateway=serial --my-transport=rfm69 --my-rfm69-frequency=868 --my-is-rfm69hw --my-serial-is-pty --my-serial-port=/dev/ttyUSB-MysGW --my-serial-groupname=dialout
make
Is it possible to create another RFM69 network on new hardware, just for the test, while my current RFM69 network keeps running on current gateway/controller?
As soon as I started another RFM69 gateway (mysgw) on new hw, even with different network id (101), most of the sensors connected to my other (production) gateway running on old hw with default network id (100) stopped communicating... so it seems it is not possible to run multiple RFM69 gateways in the same range (on the same freq).
@sebdetours said in MDMSPanel "Nextion":
Did you take a standart case that you cut out?
Hi @sebdetours, yes. This is G1910 (Gainta) box. See drawing attached to projet files.
Not yet !
In fact, the interrupt must be short enough and fast enough to be sure to not miss the RFM69 interrupts.
The code for 8 dimmers will not be really more complicated : in fact, each time we got a zero cross, we must set a timer to zero, and then wait the good amount of milliseconds to turn on the needed outputs.
So, yes, we'll have an interrupts each 10ms (each time the wave crosses the zero, to be precise !), but I think all we have to do in the interrupt handler is set the timer to zero (or to micros() ...) and then on the main loop, wait the good amount of time for each output before setting them ON.
Seems simple on paper, perhaps it will not work on the chip....
In facts, my main concern is : will the RFM interrupt be short enough to not disturb the zero crossing interrupt ?
Although, not yet tested the RFM : do we NEED the interrupt pin ? Can't we poll frequently the RFM?
@DavidZH - I really hate our electrical system here, but that is coming from an electronics guy, not a electrician. I like the idea of low voltage in the switches, however its AC. I would prefer to see DC, but the voltage drops might be something that they're attempting to avoid by sending AC instead. Yes, i agree about those damn rings and we also don't have the room here in the UK like you mentioned about the NL.
I modified MyConfig.h file and RFM69 driver to allow you build gateway (ethernet or MQTT) with W5100 ethernet and RFM69 radio modules using SoftSPI bus. You can find it at: https://github.com/gieemek/RFM69_softSPI-for-MySensors-2.1.1
Thanks again, learned a lot... I decide to give a try there, I also had a look on some components' datasheet and seems to be what I need... Let's see, if end up getting the boards I'll publish a review here later.
