Double checked the battery again just to make sure. It is in correctly (I can read the + when I look at the board) and I am still getting 3v on one pin of a small 8-pin chip on the board indicating that the solder connections are good.
Also, the station 5 “ON” icon (expanding bubble) starts off ok, but after a few minutes gets VERY slow indicating something besides (or in addition to) thew RTC problem. You can see two videos of the problem at:

and

I checked the battery pins; looked good; re-soldered anyway; no joy. I’m getting voltage to (what I think is) the RTC (1/4″chip dead center of the board; second pin in from the bottom right corner). I rechecked everything for solder problems (looked fine but re-soldered crystals because they looked a little iffy…), dissembled to check the GND-VCC and GND-VIN resistance, both above 1k. GND-VCC and GND-VIN volts both check good as well. Reassembled and it still comes up all zeros until it syncs up with NTP.Also, the other OS (#1); it works great most of the time, but somehow got “stuck” again last night. On my iPhone APP the “current status” showed stuck at “Thurs 20 Dec 2058 at 17:18” and the LCD display showed the same except “Sat” instead of “Thurs”. It had been connected to non-internet router with NTP “off”. I re-synced w/internet (NTP ON); it re-synced ok. I turned NTP “OFF” and reconnected to the other router. It stayed on time for a minute of two, then the day on the LCD turned back to “Sat”. I noticed whenever it goes to “sat” I could not connect with my iPhone and I was unable to bring up the IP address by pressing B1 (or B2). I reset it again and its been staying on track, even through a power outage last night (July 31). Update (1 Aug) still good at 11PM tonight.
I was out of town for a week: Here’s the latest info:
OS#2: Firmware ver. 205 Battery checked 2.9VDC. After a week of being off, I connected to internet LAN and time showed all zeros (I had removed the battery to check voltage). NTP synced up to correct time and date, but wrong day (Thurs instead of Monday). Turned unit off, disconnected LAN cable and turned back on: time started again at 00:00 and day/date at 01-01. This occurred twice; once with NTP “ON” and again with NTP “OFF”. Every time I turn the machine off and then back on, the time starts again at 00:00.
OS#1. Battery checked good. I found that station 5 was always on (w/o any LCD or program indication). I re-soldered all the leads to station 5 and it worked like a champ hooked up to a internet-less router…. thought everything was peachy but it hung up at 1457-1456 the following afternoon. So I turned on RTP, hooked up to home LAN w/internet. It re-synced fine. Turned RTP “OFF” and reconnected to internet-less router. I’ll see how long it lasts. It seems to work well until I connect my iphone… More to come…
I have two OS’s still not working well. I have four units total; two are working well, two are not. All DIY kits.
Troubleshooting OS #1 (Using a single program to run 4 stations for 10 seconds sequentially). Without being connected to a router, it kept good time both with w/NTP “ON” and “OFF”. When connected to a non-internet connected router (with NTP “OFF”), it started sporadic time-keeping (seconds sporadic, but overall kept within a minute of the right time). 10 second station times became 26 seconds long and station indicators on LCD screen moved very slowly. The clock self-corrected after hanging on a minute too long, then jumped ahead to correct time. As a result, the remaining stations did not turn on (program ended). This occurred with NTP “ON” as well. When I connected back to an internet-connected LAN, all worked with NTP “ON” and “OFF”. I unplugged it entirely for a couple hours and it had the correct time when I plugged it back in.
Troubleshooting OS #2: (Same program: Single program to run 4 stations for 10 seconds sequentially). It seemed to work fine w/NTP “ON” and connected to internet-connected router. It auto-corrected the time when I plugged it in. I unconnected the LAN cable. It kept good time with NTP still “ON”. I turned NTP “OFF” and it took a long time to get past “connecting”. Oddly it still showed three bars (strong signal strength) with no “x” while unconnected. It seemed to work fine otherwise. I connecting to a router w/o internet connection (NTP still “OFF”), and the clock immediately stalled and cycled between 1815 and 1814. I turned NTP “ON” and reset. It took time “connecting” again and the clock was still stalled, cycling between 1815 and 1814. I disconnected the non-internet router and the OS stayed stalled between 1815 and 1814. I plugged back in to the internet-connected router, (NTP “OFF”) and there was no change in the clock, but it “connected” very fast. I turned NTP “ON” and reset, and it synced up to correct time. It lost several minutes over the next couple hours (NTP “ON” and connected to internet-connected LAN) and when I reset in (OFF-ON) in re-synced to the correct time. I left it “OFF” for the night and when I turned it on it showed the correct time right away; before going through the connecting routine. It lost time again what left “ON” and again when connected to internet-LAN ( a few minutes each hour)
Hope this isn’t too much detail… Thank you Ray.Thank you for considering this change! In the mean time I’m still using the web interface which works great, just not as quite as “cool” as the APP on the screen of my iphone…
