What is the difference in data storage amongst the different Greenn Dot USB dataloggers of:

Davis 6510

Uksa007

BelfryBoy

Are there any other meaningful differences?

Hi,

They all use the same capacity memory chip, so there is no storage difference.
Functionally there is no difference with my logger.

It's a AT45DB011D which is 1 Mbit, with the security registers programmed.

New batch of USB Loggers running out the door, get yours now!

Remember I can supply an RS232 version if you have a specific application that requires it, along with the USB 2.0 version!

Hi, would you consider making one with the alarm output? or is that too much?
Kind regards

Hi,

How many do you require?

There would be a lot of work in developing the circuit, PCB, testing etc.
To date your the only one who requested it, so unless there is huge demand I fear it would be wasted effort.

Regards.

Bad news: The memory chips, that allow the green dot compatibility have gone end of life and are not produced anymore. There is a newer replacement chip, unfortunately it doesn't work with the Davis security used in the firmware/console. It was going to happen sooner or later!

I have purchased the last 33 chips, after that I will have to try to use a different package, long term we are pretty much in trouble.

So if you want a logger order asap before the 33 are gone.

I will update this thread with details as I develope the new logger.

Regards.

Well I just took the plunge as although I my logger works it is a serial one and so have gone for a USB one now as my Weather PC only has USB. My existing logger is a 'Bluewave' one which kinda says how old it is for those in the UK who remember that.

Hi, thank you for the update.  Considering my first Davis purchase as my old station is about at the end of it's life. I'm looking for a solution to run updates to WU/CWOP without running a computer 24/7. If I am correct, I would need the ISS, the weather envoy, and then your product in lieu of weatherlink?

Yes, but note Weatherlink includes a licence to use Davis software.
You really only need an envoy if the Console is not near a PC, It doesn't seem to replace a PC?

Generally you just use the console with the logger connected to a PC or Raspberry Pi running Cumulus or similar software.
The raspberry Pi is a good solution if you don't want to run a PC.

Very interesting in the serial logger.. Is there a way to give it more storage to hold 1 minute intervals for weeks?

Also, I have several Davis consoles - most 1.90 firmware and one 3.80 firmware (green-dot).  Will this logger work in all the consoles?  Just curious.

I already have (2) loggers (both serial - one green-dot and one older 11 year old style) that works with my older 1.90 console.

Looking for serial, flexibility if possible, and adding more storage capacity for holding log information in the event of a power outage.  It would be cool if you could use a USB key for storage.. :)

It's not possible to add more memory, it has been tried and the console still only uses 1M which is supplied on the logger.
You can select 1min intervals, the weather doesn't normally change that fast so not all that useful. I set mine to 5 min which is the same as my update rate to wunderground.

My loggers work on both green dot and older non green dot.
