So, my last extension of stay was done in Isaan.

 

Now I live in Bangkok.

 

I still have a home in Isaan and we go back several months a year.

 

Can I do my next 1 year extension of stay at the Isaan immigration?

 

I suppose I just have to update my TM thingy to say that I am living back there.

You are supposed to use the immigration office in the province in which you are staying.

So if you happen to stay in Isaan when your extension is due you do of course apply at the local immigration office there.

I think he could change to another office if he informs them that he has changed his permanent address. But if the permanent address is still in Bangkok, then no.

it depends where you got your first permit, visa, or whatever people are calling it these days.

I do the Retirement extension each year.

I got my first Retirement stamp in Hua Hin.

For that reason, I have to renew in HH every year.

If i want to change, I have to cancel by leaving the country and starting over again.

I came here on Tourist, and changed to Retirement.

I do the extension, which is a stamp in the passort each year, not a sticky visa sticker

I don't think so : I had my first retirement extension ( then 5 years ) in Hua hin, and I changed province ; I just had to tell my new immigration I have changed my address , I filled a TM 8, I got  a new tabian ban, and it's ok

no need to leave the country

That is incorrect info somebody has given you or a misunderstanding

All you need to do is change your address to a different province and apply at the immigration office for there.

The requirement to apply at the office where you applied is for the first extension after getting a 90 day non-o visa entry at immigration.

totally incorrect 
all you need do to file in another province is to file a new TM 30 where ever you want to be

If you are familiar with the procedures at the Immigration office in your old province, do it there, before you move.  This should prevent you from being blindsided by some different procedure at the new Immigration office.

My friend moved from Chiang Mai to Lampang. TM30 address of change and new 90 days report done in 15 minutes. At the same time Officer booked his OA extension appointment. Seven days later different officer granted extension in 20 minutes. 

If your place of abode has changed you do "a change of address" before doing your next renewal

preferably at the same time. Takes about 20 minutes 

It is legal, above board & no, you do not need to leave the country
