About 600 kilometres from her home in Yothin Pattana 3 in Bangkok, Ms Yingluck and caretaker Deputy Prime Minister Pol Gen Pracha Promnok watched protesters converging outside her residence on iPads transmitting up-to-date developments from security cameras installed at her home.
Pol Gen Pracha said police allowed the demonstrators to get near Ms Yingluck's place to avoid possible clashes with security authorities and hoped that they would return to the rally sites in downtown Bangkok after airing their stance outside the house.
A big turnout was at the caretaker prime minister's house in a rally led by Seree Wongmontha and Anchalee Paireerak of the People's Democratic Reform Committee.
Dr Seree read out a statement attacking Ms Yingluck's brother, convicted former prime minister Thaksin, for widespread corruption when he was in power.
He urged the caretaker prime minister to resign as the caretaker government had no legitimacy to administer the country following its rejection of a Constitution Court ruling and demanded reform before a new election is held.
The court ruled the charter draft amendment on the composition of the Senate was unconstitutional.
After the statement, Ms Anchalee and Dr Seree led the protesters away from the house and back to their main rally site at the Democracy Monument.
Ms Yingluck is on the last leg of an inspection trip to the northeastern provinces. She travelled by train from Udon Thani to Nong Khai on Sunday morning.
