Hello all,
I have a Cai webcontrol board hooked up to a relay that controls my outside light.
I have a photo resistor with a 1k resistor and this is what triggers the analog input set to turn the relay on and off, in turn switching the lights on and off.
Everything was working perfectly up until yesterday.
Now for some reason the analog input reading is all over the place.
Normally when it worked correctly, I had it set that when it reached 7 the lights would turn on, then when it reached 11 the light would tun off.
As this is an analog input I needed to give it a little buffer as as it was getting dark or light, the reading would jump a digit or two up or down.
Since yesterday, the reading is all over the place, at some point it's 12, then could run up to 50, then back down, then back up to 100, and the lights go on and off.
I noticed that this happens at night,l as I get email notifications that the lights are on and off. During the day, I think it's stable, because I don't get notifications, but will have a look at day break.
The only thing that I did, the other day, was reset the router that that webontrol is plugged in, and I also unplugged the then plugged in the web control board. Nothing else was done to the board ot the settings.
The photo resistor and 1k resistor is powered by output 8 of the webcontrol board. If I tun off output 8 then the lights stay on, as the analog reading dumps to 0. And I can control the lights manually on and off by controlling output 8. Like I said had it set up like this for a while now and all was working fine.
At this time this is the way I can have the lights on.
Any idea why this is acting this way?
What should I check, I'm not very electronic savvy, everything I learned was from this board, especially from Lou and Cai.
Thank you in advance for your help.
