It doesn't sound like speculation to me. It sounds like on days off he's had the coal build up problem and being home at the time he's opened the air control up and it's worked, and now he's wants to automate the process. Why would you automate a process without giving it a manual try.
I've read the posts from chadihman several times, and I can not find where he states such a thing. He does speculate that opening the air after secondary combustion will resolve the issue (that was the point of his thread, he was asking for opinions)... but he hasn't posted where it has been verified in any way, shape or form. And, even though what you say has been brought up a couple of times, and I've pointed out it's only speculation at this point (based on available posts)... the OP has not clarified. It may resolve the problem... it may not... but at this point, we just don't know.

I have a quadra fire 5700 wood stove and I love my burn times and heat output. My problem is I'm accumulating cherry red coals faster than I can burn them now that it's cold and I'm feeding the stove full.
My wife and I work away so I build big fires in the am and before bed. My stove puts out a lot of heat throughout the secondary burn of the gasses but after that I have charred pieces of wood that need more air to deplete them and get more heat from them.
I want to hook an electric actuator to my air control and control it with a digital timer. I'd set it so after five hours give or take the actuator would power up and open my air control while I'm at work. Then I wouldn't have try to burn so many coals down before loading again.
