Multiple EvoHome HR91 devices with the same ID

[jackbroer]

Hi to all,

I searched a lot but couldn't find the situation that I am currently seeing:
Evohome EvoTouch with 11 zones. Running fine since the beginning of this winter.
Domoticz 2020.2 on Windows 10. Running fine since last January.
Honeywell HGI80. Running fine since a couple of weeks.

One of the zones is a small apartment within my home. In this zone I have 3 HR91 Radiator valves and 1 Honeywell Round wireless thermometer.
The Round wireless is used as the central thermometer for this zone. This works fine.
Now that I see all the information coming in via the HGI80 I see that the 3 HR91 devices all have the same ID.

Because they all have just 1 ID, Domoticz displays only one device. But in the graphs of this odd device the temperatures of all 3 of them are shown. The graph is messy

. If I zoom in on it, you see that the temperatures of the 3 HR91 devices are all in the same graph

. The Round Wireless does show a smooth line

Although the set point line looks smooth, it is also the set point line from 3 devices. They are now in 1 zone, so they have the same set point, but before I tested them in separate zones and than they also showed 3 set point lines in 1 graph.

I already unbind them, removed the batteries, recreated the zone etc. But each time they come back all having the same ID.

Who can help me "separate" these devices?

With regards,
