Evohome BDR91?

[ToniW]

I have successfully setup my Evohome system within Domoticz. However: I can not seem to find the actual status of the BDR91 boiler relay, nor any hint on how to manipulate it from Domoticz. There is a 'boiler' switch in Domoticz that appears to indicate some value for the total heat demand, but this does not reflect the actual on/off position of the real relay switch.
Any pointers?

What do you use as gateway?

I use an HGI80 connected to the RPi that also runs Domoticz.

I don't have the hgi80.

I think it is possible to check the status with the hgi80. This is noticed in the wiki...

Sorry, I've only just noticed your post. Coincidentally, I'm just working on an update to the Domoticz Evohome code to add devices for each BDR91 as a few users have requested this functionality. These devices will be read-only and reflect the status of each BDR91. It'll likely be a month or so before the update is ready to be pushed to the main beta code. With the current code, the Boiler device shows the overall heat demand, but the boiler will frequently switch on and off following the TPI method.

Since version 2 of ezvents, it is not possible anymore to switchon or switchOff an BDR91 relay.
Is this because it became a readonly device?

I use the BDR91 to switch-on the flooheating pump. To avoid the pump running unnessesary.
Is it posible to change this again to a device which is not read only?

It is extremely unlikely that this is in any way related to dzVents (as I assume you meant by ezvents) as this is just a layer on top of the Lua implementation that was already there.

Thanks for your reply Dannybloe.

I think you're right that it is not related to ezvents. But that is where i discovered it.
Last night i upgraded to the new version of domoticz and ezvents and i got the message in the log that the device did not support the switchOn or switchOff method.

I think it has more to do with the post of "by DanD » Thursday 04 May 2017 10:38", where he was explaining that he was working on the evohome code
and that the BDR91 become read-only devices.

Is there a reason that the BDR91 is a read-only device?

That is not the situation here. The device that you do the switchOn/Off with is not a switch type device. What kind of device is it? (you can do myDevice.dump()). Can you post the results (hardwaretype, devicetype etc) here?

[Bertvdw]

I added in the hardware tab the device as a Relay in the evohome line as an extra relay to switch on and off the pump of the floorheating.

The result of the mydevice.dump() statement is in the attachments

hardwareid = 8
devicetype = heating
deviceSubType = Relay
switchType = On/Off
