I solved the issue by using extra I/O pins and assign a static node address from a base address + ID bits... In my case below, I used 3 ID pin's.

/* **************************************************************************** */
/*                                Before                                        */
/* **************************************************************************** */

 // Before is part of MySensor core 
void before() 
{ 

 
 // need to set up pins prior to reading them...
     pinMode(ID0, INPUT_PULLUP);
     pinMode(ID1, INPUT_PULLUP);
     pinMode(ID2, INPUT_PULLUP);
     
     myNodeID  = !digitalRead (ID0);                     // ID bit are 0 = on, so we invert them
     myNodeID |= (!digitalRead(ID1) << 1);           
     myNodeID |= (!digitalRead(ID2) << 2);

     myNodeID += NodeID_Base;                            // set our node ID

     // We no longer need these pins, so remove pullups to save power
     pinMode(ID0, INPUT);
     pinMode(ID1, INPUT);
     pinMode(ID2, INPUT);
}

This has been fixed.... It was an error on my part, I had a unlisted device with the same IP address as the GW... it was a pain to find this as GW would work for 3 to 4 hours.

I have tested removing access point and GW re covers
I remove MWTT broker and GW recovers

This is a MySensor program to control, interface with an APEX Destiny 6100(AN) Alarm panel. This is an older alarm panel, but its capability exceed what can be found on current Honeywell-Ademco panels.

Apex was bought by Ademco who was bought by Honeywell. Its is NOT compatible with current Honeywell-Ademco panels, but has the framework to be adapted.

My system has 63 active zones, most are using wireless Ademco-5800 series sensors

It read's and parses serial data from the alarm and format them into MySensor messages.

This is running on a MoteinoMEGA, and connect to the D6100 via a TTL serial interface
Radio is 915MHz RFM69HW
Tested with MySensor 2.0.0 beta
Tested with D6100 firmware 8.07

https://github.com/trlafleur/Sensor_D6100

Sensor 1
This device was designed to be a remote sensor in a MySensor or LowPower network, but can be adapted to any network that uses RFM69W(H) radios and a Moteino ATmega328 processor.
Basic functions:

1. Carrier for a Moteino processor with a RFM69W(H) radio
2. Power supply 8 to 24V AC or DC
3. Condition pulse counter with 1st order pulse filtering
4. 2 Relay outputs, that can be converted to FET output with a jumper
5. 3 Analog input with scaling and filtering, can be converted to digital I/O
6. 4 LED’s for device status
7. An MCP9800 temperature sensor, and or
8. An Si7021 temperature and humidity sensor
9. Designed to fit in a Hammond 1554C water resistant case

The power supply is designed to be run from a standard irrigation 24V AC power source, but can be run from 8 to 24V AC or DC. Input power is fused with a PTC and then connected to a bridge rectifier, filtered with a large capacitor and then connected to a Pololu D24V6F5 ($6), 5V 600ma switching power supply or a 300ma version, D24V3F5 ($4), or there is also space to use a TI TL720M05 three terminal regulator in a TO252 package.

The pulse input provides a 1st order filtering of pulses from mechanical (reed) switch as found in many water meters. Switch de-bouncing-filtering is done by R7, D3, R9, C7 and U1. The 74AHC14 inverter has a Schmitt trigger input to help with noise immunity and will provide high voltage isolation on the input. (See the reference below on how it works.)

The output of the 74ACH14 is connected to the T1, 16bit counter on the ATmega328 processor. This can be used with simple code to count pulses without the need for interrupts. This method also continues to operator during processor sleep.

This input can be converted to a conventional, input circuitry by selection components. IE: to use a hall effect sensor, you could remove R7, D3, C7 and replace R9 with a zero ohm resistor as needed.

http://www.ganssle.com/debouncing.htm

Relays are driven by a N-FET from the Moteino I/O pins. Diodes across the relay coils are for back EMF. An optional jumper connected across pins 6 and 7 of the relay bring the FET outputs to the “C” pin on J3 for direct FET connection.


On the analog inputs, two input resistors and the capacitor do analog input, filtering and scaling. Again, these components can be replaced as needed to provide a direct connection to the Moteino as analog or digital I/O pin.

If you don’t need all of the input pins on J2, you can stuff smaller connectors on the board.
Options for an MCP9800 temperature and/or a Si7021 temperature-humidity sensor. The I2C module of the processor controls these devices.

PCB files, schematics are on Github... I use Seeed Fusion for board.

A number of people have ask me about why I'm using 32bit processors when an 8bit will do. Well its simple, for small development projects of less that a few hundreds unit, the larger flash, larger ram, faster CPU, lower power devices, and cheaper raw devices, allow for faster code development... no time wasted on how to save flash or ram space.. seldom having to concern myself about CPU speed.

If I'm doing a project that requires very large volume, or special needs, I will again consider an 8 or 16bit processor, but again, these days often the 32bit devices are cheaper and more functional.

Below are a number of CPU boards with RFM69 or RFM95 Radios attach that can be used with MySensor.

In MySensor space, for my projects, my favorite 32bit processor board is:
RocketScream M0 ultra pro Ver2, RFM69 or RFM95 radio, battery connector/charger, USB port, EUI64 chip, large external flash, very low power, u.FL or SMA connector, great support...
http://www.rocketscream.com/blog/product/mini-ultra-pro-v2-with-radio/

Other 32 Bit:
Adafruit Feather LoRa M0, NO EUI64, No External flash, battery connector
https://www.adafruit.com/product/3178 RFM95
https://www.adafruit.com/product/3176 RFM69

Non 32 bit processors:
MoteinoMega LoRa, ATmega1284P, RFM69 or RFM95, EUI64 chip, large external flash, u.FL or SMA connector
https://lowpowerlab.com/shop/product/119

Moteino LoRa, ATmega328P, RFM69 or RFM95, large external flash, NO EUI64 chip
https://lowpowerlab.com/shop/product/99

Adafruit Feather LoRa, ATmega32U4 CPU, NO EUI64, No External flash, battery connector, RFM69 or RFM95

It would be great if the core documents for this project were available in .pdf format on the web site....
This would make it easy to have a local copy on a tablet or equivalent device for reference...

Thanks

See my documentation here for what I did for fuel oil, all will be applicable to water..

https://github.com/trlafleur/Tasmota-Tank-Sensor

To provide a large enough pulse to drive the ceramic transducer , you need a lot of energy, so they pump up the 5v with an inductor/transformer to provide a high voltage pulse. This is 60v or more…
The more Energy you produce the farther the pulse will travel….

Everything thing else on the board run at 3.3 to 5V.

Add a large Capacitor of 100 µF are so between the 5v and ground on the device, this may clean up your problem.. Some CPU modules just can’t supply enough current quick enough that’s needed when the pulse is triggered.

These are very inexpensive device, we’re luck to see them work at 1/2 the spec range.

It would be nice if you could post a .pdf of the schematic.... not everyone has the tool to see the board from the .sch file.

Well, that news to me. I've always use the HCW variant and did NOT noticed the pin change. My error for not looking at the detail... (This was not the case with the RFM69W and HW radios, both shared the same pin-out)

but again, using the HCW allow one to also use the RFM95 radios, and if you keep power below +13, power consumption is about the same... also the new RFM69 radio driver in 2.2b use adaptive power control as an option, this keep power use to a minimum saving power.

I just re-checked the data sheets, RFM95 and RFM69HCW do share the same pin-out.

Yes, The H = High Power version, C = Compact version 16x16mm pkg, vis 16x19mm pkg

My error, RFM69CW and RFM69HCW are available, also note that if you do not use the power over +13dbm, power consumption is about the same between the radios.

Both the RFM69HC and RFM69HCW are available in the smaller package.... again, this would allow RFM95 to be used.

Thanks...

Is this board using the RFM69HCW footprint so that one could also use an RFM95??
If not, please consider this change and you might want to consider as an option for DIO-1 connected to an I/O pin on the CPU.. (this would also make it compatible with LoRaWan network)

Thanks

I use the standard Arduino IDE for most things but moving to PlatformIO as it's editor is so much better that the brain dead one in the Arduino IDE

@gohan Pro-mini, is a great part, but sometime you need a lot more! 32 bit is the future for me, less power, less cost, more resources....less hassles...
