i have some weird problems with and AC dimmer that i bought on Ebay: http://www.ebay.com/itm/AC-220V-110V-4-x-1500W-Channel-Digital-Phase-Controller-Dimmer-Arduino-Like-/281550086135?
I edited the code so i can control the dimmer also from the Serial port(needed for my home automation). Everything works flawesly except that the dimmer is very sensitive to the other loads on the line.
For example: When the light on the dimmer is on highest value, the light blinks some time when i start or stop shades motor, or vacuum cleaner, or any other electrical motor(it looks like the light is for a 100-200ms off).
Example 2: When the light is on the half of its value and when i start or stop some electrical motor, the light goes for a 100-200ms to its highest value.
Could there be any problem in the code or do i need to add some RC filter(snubber) or something to the network?
I will post the code if needed. Thanks.
