Winger Aiden McGeady was once again Sunderland's hero in the draw with QPR, netting his third goal in as many games.
The 31-year-old scored his fourth Sunderland goal of the season in the draw, curling home a left-footed effort on the hour mark to rescue a point for the hosts.
McGeady bounced back well after missing a glorious opening in the first half after being released through the middle by fit-again Duncan Watmore.
His through ball sent McGeady clear but he blasted his effort wide of the post, McGeady sinking to his knees at the realisation of a glorious chance wasted.
Idrissa Sylla made him and Sunderland pay eight minutes before the break, nodding home a corner from close range only for McGeady to equalise with another stunning goal.
"When we’re at home, we want to break that hoodoo and win games," said Grayson.
"I thought we started okay, but we knew the first goal would be important and we had a couple of decent opportunities before they scored.
"More times than not, McGeady will at least hit the target and make the keeper work. He’s quite surprised himself that he didn’t hit the target.
“With his experience and how he plays, he knows he’s going to make the odd mistake because he tries things other people can’t do or even attempt to do.
"But he’s always going to want to get on the ball. We had to be braver in the second half, and I thought Jonny Williams and Lewis Grabban both made an impact in the game from the bench."
The point leaves Sunderland second bottom and three points from safety after 12 rounds of Championship matches.
It was also another chance of ending the home hoodoo wasted.
The Black Cats haven't won a league or cup game in front of their own support since the middle of last December.
Grayson added: "It’s frustrating for everybody because we’re just desperate to win a football match. Whether it’s home or away, we want to be winning matches.
"With where we are at the moment at home, the first goal is always so vital. If we had got it, then it might have changed the whole perception of the ground.
"To be fair though, when we showed signs of playing with the right tempo, with and without the ball, the supporters were good.
"I know they’re frustrated with certain things when they go wrong, but that just happens in football.
"The players reacted well to the situation they got themselves into."
