Wattermeter from GWF - Readout with M-Bus Port - How to?

Snowest last edited by

Hi,
I would like to be able to read how much watter me and my family are using in a day, week, month and year. My Wattermeter brand is GWF (Swiss company). I don't know them but it seams that there tool has a M-Bus port. Wich I can imagin that would be great.

In my dreams :), I would be able to connect a little sensor to this mbus port and this sensor is sending the information on my openHab system. I do also have a homematic system, maybe this would also work with this.

And the same company has a M-Bus solution

Thanks you verymuch for any kind of help

@NotYetRated Hope you'll find good uses and a fun time while building your sensors.

@Kokosnoot good solution. I remember the discussion in the early days of MySensors. I've powered the radio's for most of my sensors from the 3.3v regulator on the arduino board and for me that works perfect. But for my latest designs I decided to add a separate ams regulator for my radio's like the guys suggested in the beginning. Because you basically want the on board regulator to power the mcu only.

We are of like minds, Don't like the cloud based controls (that's another discussion). In my case I have a Bryant/Connex system, heat pump, variable speed fan and 4 zones. There's a lot going on: the 4 zones creates 16 profiles. The fan speed for a profile will depend on the indoor and outdoor temperature. The thermal fluid pump also has to be controlled. A profile will have an optimal air pressure, so there's a sensor there. The controller works just fine not being connected to the cloud. But I want to set the parameters remotely, Bryant/Connex can do this. I also wnat the status of the various actuators and sensors to show up in Home Assistant. The signals sent over the RS422 are proprietary. My plan was to reverse-engineer the signals. After doing this I'll have to experiment to get the right mix of air pressue, fan speed and thermal fluid flow for each profile. I'd like to do the same for my AO Smith heat pump water heater. I'd like to follow your progress. OSD

Hello everyone, Firstly, I apologize for reviving such an old thread, but I find myself in a unique situation and was hoping some of you might be able to help. I hope everyone's doing well. I have a specific inquiry that I couldn't find a recent solution for. Does anyone here know of a tool to generate "fake" Dooya remote (DC90) RF codes for curtains? I've acquired a few motors without controllers and am trying to integrate them with Home Assistant and Bradlink RF remote. Specifically, I'm searching for a way to generate codes for the Up, Down, Stop, and the "Set" button functions to configure curtain limits. Any insights or guidance would be immensely appreciated. Thank you so much in advance!
