Other than the above thermostats I found few thermostat like the Beca,Beok or Qiao xi pan on which are chinese manufacture selling on Amazon but is available for purchase in Alibaba.These thermostat are not so reliable for obvious reason but if you want a thermostats quite low in price you can find multitude of these thermostats at aliexpress.com and find them or similar other wifi thermostats quite easily there and get it mailed through cheap china post.But as said these thermostat wont have the customer support or maybe clear installation instruction as i read in few of the reviews for models sold on Amazon.
