Evofw3 in Domoticz

[roblomq]

Short question. Is it possible to use this evofw3 in Domoticz combined with a nanoCul? If yes is there some guide on how to do this?

[ghoti57]

Evofw3 will work on a nanocul.  I recommend the later versions based on an atmega32u4 rather than the atm328p devices, they will be much more effective at capturing RAMSES messages.

I can't suggest any guides for using it with domoticz, search the forums for references to HGI80.

Alternatively if you are not committed to domoticz yet, look at Home Assistant and the custom component ramses_cc. https://github.com/zxdavb/ramses_cc

As an alternative to a nanocul I sell this device pre-loaded with evofw3 https://indalo-tech.onlineweb.shop/

I already use the Domoticz plugin that uses the web API which works fine but what I'm missing there is the best demand of the zone. So I was hoping when using the nanocul this heat demand would be visible. So I already bought your nanocul 😅

I've found the instruction below.

https://www.domoticz.com/wiki/Evohome#Adding_Evohome_via_usb_device_.28HGI80_or_equivalent.29

This gives me 18 devices in Domoticz but they are all boiler related, I don't get the zone information from the nanocul. What isn't completely clear is how to obtain the Controller ID, I now used the crc from the Evohome device but not sure it's correct.

[ghoti57]

The controller ID is visible in all the serial messages. 

If domoticz doesn't allow you to see them plug the SSM into a pc and open the COM port that will appear with a serial terminal device (e.g. putty).

The messages are printed as they are received in a fixed format that has 3 ID fields.  Anything like 01:xxxxx is the controller. 

That's about all the help I can give because I have no first hand knowledge of domoticz.

If you're only using Domoticz for the evohome system you should still consider switching to HA.  There's a lot of ongoing development.

If you're using the SSM in either system the add-ons that go out to the Honeywell (Residio) web interface are irrelevant on both systems.

I get the following:

So then is 224380 the ID?

[roblomq]

I used the 224380 in the "Controller ID (hex)" field of the Domoticz hardware settings but nothing changes still no zones and only 19

Some of the log info from Domoticz

[ghoti57]

The controller ID in the formatted message is 01:224380 These DECIMAL fields are a representation of a 24 bit value 0x076c7c

Try this hex value as the controller ID.

[roblomq]

That seems to be working. Thank you!
