Nefit Multiline is not visible on EMS BUS

[hendrik4711]

Hello,
I am Hendrik
My Nefit Multiline heatpump is connected on EMS.
No details show up on EMS ESP
Trendline gas heater and moduline 400 are visible.
I tried the servicekey plug and the ems connections.
All units are visible but no heatpump info.

any clues?

regards,
Hendrik

Hmm, looks ok to me. The heatpump is a hybrid type with 76 entities,the gasboiler is cascaded as heatsource with no entities,only managed by the hybrid. What entities are missing?

[hendrik4711]

When I remove the hybrid heatpump from the bus, I see the same messages. Then under the gasboiler.I would suppose the heatpump would show it’s own info too.E.g. settingsIf it’s on pump is workingIf the compressor is running.Errors.Just like it is shown on the moduline 400Regards,HendrikOp 4 okt 2023 om 11:45 heeft MichaelDvP ***@***.***> het volgende geschreven: Hmm, looks ok to me.

As far as i understand the hybrid heating acts as a single boiler and the hybrid uses different heatsources not visible to the bus. We have added this in #495 and i can not see any new telegram or heatpump specific telegrams.

Hm,Thanks a lot for the info and quick responses.Heatpump has all leds and info inside the unit’s closed metal enclosure.So nothing is visible from the outside when no moduline 400 on software >= 3.05 is connected as thermostat. (I use a Tado).I was hoping the gateway would help me with this.Helas.I guess/hope I can connect Tado parallel to the moduline.Moduline on status of in read only mode.Cheers,HendrikOp 4 okt 2023 om 19:02 heeft MichaelDvP ***@***.***> het volgende geschreven: As far as i understand the hybrid heating acts as a single boiler and the hybrid uses different heatsources not visible to the bus.
