I have also an Remeha Tzerra boiler, and I want to connect it to Domoticz as well. I already found that the Tzerra is a PCU-05_P3 machine as defined in the xml files of RECOM. However now I would need some help with the reverse engineering of the work already done for the Calenta. I will start with ...

I have followed the instructions on the google docs page, and created the user variables, there is no further instruction about creating specific parameters, besides this part in the code: function My.TimeDiff(Time1,Time2) if string.len(Time1)>12 then Time1 = My.ConvTime(Time1) end if string.len ...

I get the following error: MyFunc.lua:62: bad argument #1 to 'len' (string expected, got nil).

I already solved some errors, however I don't know where to look to solve this one.

Could you be of any help?

I've solved the problem by switching to an ethernet based gateway, now everything works fine.
And indeed use the "accept New Hardware" button.

That solution works for devices attached to rfxcom gateways, however not for a mysensor network. Previosly i had to assign a different node id manualy otherwise the nodes would end up in a already excisting node.

I have a problem with the my sensors gateway. I'm unable to connect any node to the gateway after I had to reinstall the complete system after a power failure that corrupted the SD card. I reinstalled the whole system using the SD card image, and after that I restored my backup I made earlier. But ...

In the domocookie there is an entry for api.thermosmart.com. However I see an # in front of this line. Could this be the problem?

I'm using a mac to run domoticz on, and the folder is writable as far as i know. I will check however the write permissons on the folder and subfolders.

I did use the same username and password combo. In the thermosmart settings window, in the thermosmart website, do you see a domoticz entry?

When I add the Thermosmart hardware I fill out my username and password, however in the log I get a message: Invalid login credentials provided.

I'm sure that i filed out the combination correctly.

What could be wrong?

I have to agree with mastair. If the functionality is embedded in domoticz this would make it a lot easier to use and implement for the "common user".
