It's never unwise to keep educating... we all need reminders even about "common sense" items... the same is true of changing batteries in smoke detectors, etc.

We were constantly getting more efficient panels and batteries such that when we went to provide warranty service on a customer three years later, the old technology wasn't even available to replace some components with.  

This is what the article explains:The Changsha-based company spent 4½ months fabricating the building's 2,736 modules before construction began.

I'm trying to stay away from the Cadillac software products since I only need some of the modules.

The shared backyard is filled with their junk which the tenants in the other unit complained about.I did a civil and criminal background search on the tenant and he has been evicted twice and has an extensive criminal records including multiple drug charges, break and enters, battery and assault with a weapon.Here is a picture of their backyard treasures:

Cops get away with everything, including assault, battery and murder, and don't even lose their jobs over their criminal behavior.

I lucked with him out because his criminal report showed that up until 6 months ago he was serving 11 years of a 13 years sentence for assault and battery of his wife (including throwing acid at her face).

From time to time this system adds new modules you can buy for a cheap price but is not required.

To control the brightness, we use PWM (pulse width modulation).  

How do I upgrade to Plus or Pro when the module involved is disabled, and has been for days?
