Copy from Fibaro forum
"I too am seeing issues with the heat controller and external sensor not opening the valve when the room is colder than the setpoint and not closing the valve when the room is (much) warmer than the set point.
To make things worse, I am a HomeSeer user and have no way to apply a firmware update when it is released. My distributor (Vesternet) will not offer an upgrade service and will only offer a return and “hopefully you will get the right firmware if you purchase another one”.
Can you (Fibaro) please consider again those of your customers who may have invested lots of money in your modules but use another controller?
I personally can’t see ‘reverse engineering’ being a big risk and even if it were, there are many ways you could put firmware out there without it being accessible to prying eyes. (Encrypted files applied through a small standalone application, for example).
In this day and age releasing products that will inevitably need firmware updates without providing an accessible means of applying those updates is very limiting. Having invested hundred of pounds over the years in HomeSeer software I don’t want to have to spend more money on tools to make the products I have bought in good faith work. I don’t have to buy hardware to apply firmware updates to other things (PC Bios, RFXCom, Aeon Zwave modules, Bluetooth headphones, Amazon kindle, Amazon Echo, Apple iPhone etc. etc. etc.
Hopefully you will find a way to allow all your customers to keep their products up to date. I have my fingers crossed."
