In oct 2015 (Presizely 17 october 2015) i bought a wifi controlled 1 ton onida ac from snapdeal (Onida 1.0 ton 3 star s123smh). With a this model of ac i can control the ac using my phone instead of searching for the remote-control and control the ac from anywhere. I can even see the power consumption and cost of consumption of the ac. I bought the wifi controlled ac because i was very fascinated with the technology.

When the ac guys came to install the ac, it did not start because they found that the pcb of the ac had a fault. The ac was going off on the start-up of the compressor. So they had had to order for a new pcb from mumbai. After a week a technician came to fix the problem. The ac did not start even after installing the new pcb.
In our area the voltage is little lower at night and proper during the day. Even in proper voltage condition (220 volts) the ac did not work. I even installed a everest 4 kva wide range stabilizer which can handle voltage from 140v to 270v. But this also did not help me to start the ac.
After several attempts and visits by the onida technicians, it was found that the wifi enabled pcb had an issue even in proper voltage. The technicians installed the pcb without the wifi and it worked fine. Well, this was a temporary solution so that i can start using it.

It was also noticed that, when the wifi pcb was installed, the display used to flicker. It used to flicker as if there is a loose contact. It was something abnormal with the ac.
But when i told the technician about the problem, he said that display flickering is not an issue. It works that way only. I don't think it should work that way. If yes then why should it?

The technicians and the manager was very cooperative and friendly. They tried their best to fix the problem. It was later said that the ac works perfectly in the cities because of the current voltage. Last month (April) a technician had a visit to try again and see if they can start the ac.

Since november 2015 till present (May 2016) i'm still using the ac without the wifi. The problem is not yet solved. I requested the local manager to forward this issue to the onida ac r&d team so that they can rectify the issue with the wifi ac. If pcb without wifi can work then why can't the pcb with wifi?
