Sorry for the late reply, our second son was born just 2 weeks ago.... no sleep anymore

It looks like this one, except mines it labelled: 0935VI, the one on the link 0935VJ

@Koresh

Ermm... how do I know it works correctly ?, and if it doesn't work correctly which 1M resistor do I have to use ?

Thanks for your help !!!

Alex

@Koresh

Hi,

I got all the parts, but I think the NRF24L01 is the normal version and not the + version, there is no + to be found on the chip.

Would the older NRF24L01 ( without plus ) work on the board ?, or do I have to use the R1 resistor ?
( Resistor 1M ( which package size ) - unnecessary element (R1 can be mounted for backward compatibility with nRF24L01, nevermind)

Alex

Nice !!!

I am still waiting for some parts to arrive from china

Alex

@Koresh

I got as reply from dirtypcb's, they changed it to 1.6 mm

Alex

@Koresh

I have both versions ( SMD and THD ) crystals on order with aliexpress now

As for the LDO regulators, I will wait for the PCB's to arrive before making assumptions

Now I have to wait some weeks before everything arrives ........and then my first smd soldering experience !

Alex

@Koresh

Found the smd quartz crystals

Alex

@Koresh

Hi, the bom says 2 x quartz crystal

I did not know they where different and one should be smd.

Could you tell me which quartz crystals I should get ?

Will check out the datasheet for the LDO

Thanks

Alex

@Koresh

Couple of questions

How to mount the second Quartz crystal ?, there are no holes in the pcb

The LDO regulators are mounted next to 4.7uf capacitors, is it correct that the regulators and capacitors are connected to eachother on both sides ?

On the photo of the assembled pcb it looks like this, but on the photo of the plain pcb and the schematic it look different.

                                           | Pin 1
                                          IC3
                             Pin2    |          | Pin 3
        Are pin 2 and 3 also connected to the capacitor left and right pin ?
                          Left pin   |    C14   | Right pin

Thanks !!

@Koresh

Let's hope the change it

Would it be possible to mount something like this on the pcb ?

@Koresh

I mailed the people at dirtypcb, hopefully they can change it for me.

If they cannot change it, would it be possible to get rid of the antenna and mount a pa/lna antenna ?

@Koresh

I renamed the gm2 file to gml ( see: http://jrainimo.com/build/?p=642 ), and was able to order it from dirtypcb.

Alex

@Koresh

Hi,

When I try and order the pcb's from dirtypcb I get the following error:

PCB #17568: No board outline (.GML/.GKO/.GBR) file found.

I made a zip file with cam.drl, main.gbl, main.gbo, main.gbs, main.gtl, main.gto, main.gts
when I try to upload this on dirtypcb I get the error message that there is no board outline.

regards

Alex

@Koresh

Thanks

Will search and find the cheapest offers on Aliexpress

@Koresh

Thanks, i found everything on Aliexpress, except:

Push Button SPDT
Resistor 1M ( which package size )

Alex

@Koresh

How do i know it;s a polarized version ?

There are these ( which i think are the wrong ones )

This would be the first pcb's i order, how do i know which component goes where on the pcb ?

Sorry, i am confused

How do i recognize the 4.7uf polarised capacitor ?

Thanks !!

Alex

Looks like what I have been looking for !

Any progress on the gerber files ? ( so I can order pcb's )

I was looking through the list of materials, but getting confusion while looking on Aliexpress, is it possible to share the links to the parts on Aliexpress/eBay ?

Thanks !

Alex

@Mediacj

I am still working on the S0 sketch, the problem I have is how to set the starting value, how did you solve this ?

@sundberg84

I cleared the Eeprom from both gateway and sensor, then set the V_VAR2 on the sensor on a start value for example 5555

I changed the sketch not to request any values from the gateway

When the sensor gets it's first reading it's registered in Domoticz with the value of 5556 ( 5555 + first reading of 1 )

Now I have to questions:

After the first reading ( 5556 ) is send to Domoticz I can change the sketch back to where it requests the reading form the gateway ?

But if the sensor for example quits working for a week, then I have to change the V_VAR2 on the sensor again, which is not very handy ?

Thanks for the help !!

Alex

@sundberg84

With connecting I mean power it on and have it count.

I am wondering why the sensor should get the readings from the gw ?, the only thing I want is the sensor to send a signal to Domoticz for every pulse it detects

Alex

@sundberg84

I did that, but it did not help.

From my observations sofar:

• Changed the settings in the Domoticz database ( for example: changed the value of the my solarpanels to 3424000 kwh )
• Waited a couple of days
• Erased the Eeprom of the sensor
• Connected the sensor
• Domoticz shows 3424.000 kwh as it should be
• On the first watt read by the sensors Domoticz shows 3642.150 kwh, this value is nowhere
  to be found in the Domoticz database.

So the next thing is to erase the Eeprom of the Gateway, it might be that the Gateway still holds a wrong value from testing.

Regards

Alex

Mhhhhh.. forget what I wrote, I still get strange readings.
Next try will be to clear the gateway's Eeprom

After a couple of days troubleshooting I found a way !!

Steps:

• Clear the Eeprom of your sensor ( there is a sketch for this in the mysensors librairy ), this because your sensor keeps the readings in Eeprom
• Reload your sketch
• Connect the Sensor to Domoticz, it will be seen in Domoticz as a new device.
• When the sensor starts it has a cleared Eeprom, it will request the values from the gateway, the gateway will request them from Domoticz
• Connect the sensor to whatever you want to read, and wait for the first readings in domoticz
  ( when the sensor sends it first reading it will replace the values it got from the gateway with the values it has in it's own Eeprom, thus sending a wrong reading, when we clear the Eeprom we don't have this problem.
• Backup the domoticz database from domoticz

Then use the procedure from my previous post:

( make a backup of the database )
Use SQLLite Expert Personal to edit the database
Go to "Device Status" and look for the row on the right side with your device
Double click on the row, goto "SValue", edit this: it should read something like:
000.000;3424000 ( the first part is todat usage, the second part total usage

click ok, click ok again.

On the leftside goto "MySensorsVars", click on it, on the right side you will see your MySensors devices, click on your device and edit the "Value"

Both SValue and Value should be the same and match whatever your whatever meter reads when you start using your sensor.

Goto Meter on the leftside, sort the "device row id" find your device id and edit the value here to ( it could be that when you have a new sensor there is no entry here )

Stop Domoticz
Copy de Databse to your pc
( make a backup of the database )
Use SQLLite Expert Personal to edit the database
Go to "Device Status" and look for the row on the right side with your device
Double click on the row, goto "SValue", edit this, click ok, clock ok again.

Then the most important one:

On the leftside goto "MySensorsVars", click on it, on the right side you will see your MySensors devices, click on your device and edit the "Value"

Both SValue and Value should be the same and match whatever your whatever meter reads when you start using your sensor.

Which poles do you mean ?

Btw, which sensor do you use for your water meter ?

Right now i use a metal detector connected to a piface ( see https://www.domoticz.com/wiki/PiFace )

I tested this sensor with the watercounter sketch and it worked perfectly, so i only have to move the wires from the senor from the piface to the mysensor arduino.

Cool !

I will try it lateron ( at work now )

Building 3 separate sensors ( in order to get rid of the piface-2 in Domoticz )

• Water meter
• Energy ( solarpanels on the house )
• Energy ( solarpanels on the gardenshed )

Next challenge would be to get a battery level in the sketch

Alex

Hi Mediacj,

Are you using the S0 bus of the lightsensor to messure your solar panels ?

If using the S0 bus, how did you wire it up ?

Thanks

Alex

Hi there,

I want to connect 2 kwh meters using their S0 bus ( instead of using a light sensor ).

Each kwh meter is going to be connected to their own sensor, which should send the data to a Domoticz gateway.

Used the wiring diagram used in http://forum.mysensors.org/topic/1013/contest-my-12-input-high-precision-pulse-counter-kwh-w/6 and the energymeter sketch.

I do get a reading, but it's totally off

Is there someone out there who has a working mysensors sketch using a S0 kwh meter ?

Thanks !!!

Alex
