My shower is either luke warm or hot my faucets are good how do i get temprature control
If all the other faucets work, then the problem is the mixing valve in your shower. You will need a new shower fixture.
SOURCE: Water is either hot or cold - no in between.
I found a way to get warm water in the shower, but I'm not sure it qualifies as a solution. After trying everything else I thought that maybe when I was feathering the faucet in the shower toward the cold side so I would get warm water that at a certain point it blocked the flow on the hot water side enough so that the sensor in the hot water heater sensed there was no demand in the line and it shut the water heater off. To test this, I went to the kitchen and turned the kitchen sink faucet all the way to the hot side and then turned it on so that I got a small flow of water. I waited for the water to get hot to be sure the hot water heater was working. Once it was hot, I left it running to keep demand in the line and then I went to the shower and turned the faucet on. When the water got hot I started feathering the control towards the cold side and soon I had warm water. So I think I'm right in that the sensor in the hot water heater was shutting the water heater off when the demand in the shower was lowered to a certain point when I was trying to adjust the water temp in the shower.
So now I can get warm water, but it means I have to leave the hot water running at another fixture in the house to create a false demand in the system so the hot water heater doesn't shut down. Is there a way to adjust the senor in the hot water heater so that it will stay on when I'm using the shower only, so I don't have to waste water by running another faucet when I want to take a shower?

Will the water stay hot in the kitchen sink? Try to isolate the problem. If it is happening at all hot water locations, then it will be related to your water heater. If just in the shower then it is related to the mix of water ratio coming out of the shower hear. If its only the shower, then you are getting too much cold and not enough hot through the pipes. This can be very simple to fix by replacing the handle going to the shower. If this does not work then you may have a problem in the hot water pipes. After you isolate the problem, please post another question here.
SOURCE: The temperature in my shower is very luke warm
Do you mean the other faucets in the house are hot and only the shower is warm? If so there is an anti-scald adjustment on the faucet that needs to be turned up a few notches. Havent adjusted a Grohe faucet but most faucets you rmove the handle and behind the handle is a nothced adjustment ring that prevents the faucet from getting too hot. This ring, or stop, is pulled out and twisted clockwise(or counter clockwise to set higher or lower max temp, then pushed back. maybe you can look up grohe to see which way ring or stop adjusts for hotter water.

Also check that by-pass valve(s) is/are, in proper position at back of tank.
