40 days have gone by and the improved 1132CU has not had a single issue. It has worked without flaw. It has gained 28 seconds in 40 days. Thats .7 seconds a day. This is quite good considering its only a basic crystal without any temp regulation. That implies it will gain about 4 minutes a...

Its been 17 days now. It has gained 15 seconds. Nothing weird and it has performed flawlessly. It has been doing all my timer based events. Having 2 1132CU's has been very helpful. I divide the programming between 2 modules and this allows more multitasking to occur. I can run more stuff at...

Your welcome Im not done though. After freezing the unit for 48 hrs at 11F it has _NOT LOST TIME_. This is kinda amazing. You would expect some drift based on temp. This did not occur. So it seems that even if a consumer places the unit in a garage in winter it will still keep accurate time...

At 4 hrs its still alive and it has lost 1 second. This is still a good result of about 4-5 seconds a day. The real test for the module I cannot do easily. Injecting massive power line noise at various frequencies and power levels and see what happens. This is the only thing I could think of...

I have placed the 1132 in my freezer at 15 degrees F. So far its working after a hour. I will leave it there for 24hrs and see what happens.

It has been very consistant. A slow, stable drift gaining a second or 2 a day. I do set back of the thermostat during my work day so the temp has varied from 69-72 at night and from 78-84 during the day. I also think the initial 30 second jump was for some weird unknown reason as it has not...

Again almost perfect time keeping. It was slow by 1 second. Zero weird events and no time changes. Its been perfect. The only unexplained thing was at the beginning. Somehow it gained about 30 seconds in about 6 hours.

Even bigger Hmmm..... Last nights midnight update from the RTC was exactly correct. In 24hrs it stayed right on time. So.... Maybe the unit was still getting thermally settled in and not stable the fist day. Its possible. I need time to evaulate it further. It may well be that its keeping...

Hmmmm.... The crystal based RTC is gaining 2.3 seconds per hour or about a minute a day. This seems like a lot. 30 minutes a month seems excessive. Im going to keep watching it to get a better feel for what the trend is.

I got the "new" 1132CU today... I think I mis-interpreted what Smarthome said. I think I assumed more changes then they did. Looking the the module the parts did not change and the layout did not change. In fact the only change was the addition of a RF absorbent material to the inside of the...

Also.... I just checked my modded 1132CU accuracy. I have not set it in 4 moths. It has gained a solid second. I checked carefully making sure my computer was very updated to the National bureau of Standards using Tardis. I gained a second in 4 months. This is a fairly stunning accuracy. So...

Another IMPORTANT update on this thread. First off Smarthome called me today. They said they had read through this thread way back in june and took it quite seriously. In fact they have redesigned the 1132CU !!!!! Based on what I did !?!!!!! Wow !!! 4 months are we have a redesigned module...

Another update. Its now almost 3 moths after setting the time on my 1132CU after the mods. I still cannot measure any drift. Its still less then a 1/2 second off. This is a fairly stunning accuracy for a $5 chip. At this rate it would take 30 years to be off by one minute. At most.

This WOULD scare off burglers.

Exactly... A eBay Crestron would just be fun to play with.. THAT was my point on page 1. Ok, im done. Im not comming back to this post. Im gonna go play with my Smarthome 1132CU and Smarthome Manager.... Hahahahah.... Talk about unrealiable and bad hardware !!... What I wanna see is that...
