Hi Ole
I have the ztrm2 and i talked to heait a couple of days ago, they will publish firmware files soon. You only have the otz file, you need the bootloader also. I bought the sw cable that sells on elektroimportøren. As this was the easiet method to update them. Just take the zwave module out, and plug it into the computer and update firmware & bootloader.
Im thinking of changing gateways. Regarding z-therm2. (I dont have a floor sensor). So i need to the included room sensor in ztherm2 or use P mode. The internal sensor is garbage, and i want to use a multisensor 6 in the same room as ztherm2. Can openhab get data from that sensor and turn ztherm2 on and off based on that from that device? Then i need to set ztherm2 in P mode. Also what does the Parameter 12 do, does it specifiy how long it will be on before turning on, i see you use both value 2 and 5. Just curious what they do.
I was just thinking doing a rule that if temp < 20 degree -> turn on ztherm2. but only if people are home.
if no people are (at work or night mode) then if temp < 18 degrees -> turn on zhterm2. Else turn off
Im not so familiar with openhab so i dont know if they have home/night/away modes or if its easy to setup.
