Confused about interfaces
Posted: Tue Oct 27, 2015 5:28 pm
I am considering building an OpenTherm gateway because I would like to control my heating with Tasker on my phone, and this seems to be the only way to do that.
In the past Kiwi-electronics sold a LAN and a Wifi version but all traces of these things have been erased. I can't find anywhere what parts I need to build one of these and what they where capable of. How did the Wifi one connect?
If I understand correctly I can build the USB version and attach a Raspberry PI to it and then just use Optentherm Monitor and send commands from my phone using MQTT or use the web server. Is this the case?
Would there be another way that does not require a Raspberry Pi to be on constantly and connect directly to the gateway. Was the vanished Wifi version capable of this? If yes, is there still a parts list an firmware somewhere. I would like as little devices as possible.
I have an Intergas Kombi compact and a Honneywell round, the typical Dutch social rent stuff. I am only interested in controlling the setpoint from Tasker on my phone as cheap as possible with as little devices as possible.
