Update history since v2.5
- When using a provision server, if a defaults File property comes in the get key answer, download a new defaults file and restart
- Disconnect Wifi from trying to connect while configuring AP mode
- Upgraded to Arduino EspCoreVersion 2.4.0
- Fixed stored SSID deletion introduced by Wifi.disconnect()
- Added a 3s delay when unconnected to Wi-fi to give time for the ESP to connect. Seems ESPCore 2.4 connects slower
- Added 2400 bps baud rate option
- Fixed date DST start and end day were swapped.
- Configured preConfForce boolean to force connection to pre-configured SSID every time nwts boots when no configuration is saved
- Configured HTTP timeout for HTTP Get queries - default value 1s (1000 ms) so as not to block the ESP because of the query
- For debugging purposes, Serial is started before reading the configuration. After configuration read, flush and new speed is set up
- Fixed flag of unsaved configuration - it now shows correctly as "never" in the webpage
- Added 1s delay after IP messages
- Reduced IP message period to 30 seconds
Version 2.20 - 20190210 - stable release
- Upgraded to Arduino EspCoreVersion 2.4.2
- Added support for multiple NTP server list (separated by a space)
- Version 2.21 - 20190701 - stable release
- Added support for PUYA chips (change is on the ESP8266 core function ESP.cpp file):
nwts has been slowly maturing - after one year, refining the device operation, listening to customer feedback and adding new requested features has made us now reach version 2.5.
The following features are now available:
All units shipping from today will include version 2.5 by default

On the past few days I've been collaborating with Howard Constantine of Oscilloscope Clocks and Nixie Clocks at http://oscilloscopeclocknixiecrt.com/. Howard produces, as the name says, Oscilloscope and Nixie clocks and the GPS enabled models are now certified as nwts compatible.
Howard has tested nwts with his Kickstarter Nixie Clock VII and it works with very minimal modifications.
nwts can be fitted under the clock. Howard's instructions couldn't be clearer:
Thank you Howard!
nwts has a lot of potential to be more than a simple GPS emulator just to set the time from UTC.
There were several requests from customers to extend nwts' functionality.
Last week we released nwts version 2.1 beta. This version includes:
Some customers requested the "Clock drift correction" option:
Two clocks from my customer Jeff Walton: on top there's a Nocrotec Bluedream and on the bottom a PV Electronics clock. The Bluedream clock has a constant delay of -3 seconds, so when connecting the clocks to the same time source, there's always a noticeable 3 delay on the Nocrotec displayed time.
Changing the drift in nwts on the unit that has the delay, increasing it to 3 seconds, makes the Nocrotec clock align the time with the PV Electronics clock.
Here's Jeff's configuration. You can also see the time zone and DST parameters.
The release version of nwts 2, version 2.2 will be available on Sunday, April 2nd 2017. All new nwts units ordered after this date will include version 2.2.
I'm very happy I can add another "non-nixie" clock to the list of supported clocks. All of this thanks to both Chuck and Bob!
When we started in the beginning of December 2016, we would never expect to sell over 30 units in less than one month.
Currently we're out of parts. We're waiting for some - we tried a new supplier - and it's taking more time than we antecipated. The holiday season doesn't help too! We were not worried... we expected nwts sales to go steady but slowly.
However thanks to Ian's excellent review at Tube Clock Database and word of mouth, we've seen a surge with customers buying sometimes more than one unit.
We have new parts arriving anytime now.
We'll let you know!
Thanks for trusting us!
One of my customers, Bob, approached me if it would be possible to connect nwts to this Jeff Thomas GPSII clock.
I answered that if it supported TTL or RS232 for the signal and NMEA messages, it should work...
Well, not so fast. As Bob noticed, it looked like nothing was happening after plugging nwts to the clock.
Contacting John Miktuk (oldvan.com) who designed the software of the GPSII clock, it was clear that my nwts device was not sending the NMEA string as required by this clock.
A small correction on the code, lot's of hardware work from Bob and now nwts is also syncing a piece of Nixie clock history!
Thanks Bob for the valuable input on nwts!

nwts is finally available for sale.
