It is common knowledge (after reading forums) that this is a very common issue with these thermostats. The E5 code (wifi not connecting) error appears to be a problem with most of them. If I had not received this thermostat for free as part of a promotional offer I would strongly urge anyone not to use or buy these products. I have had to return 3 of these units, each time within a week of receiving them, at my own cost (until the device was checked and I was reimbursed). At one point I was still waiting for my money to be returned to my bank and had to pay for another thermostat while I was waiting for another unit to be delivered! Just waiting for this one to go the same way. Cheers for the belated request for help though.
