I used to use Domoticz on Synology for years. But then gave up and moved over to QNAP, for the Virtualisation Station. Now I run Domoticz in an Ubuntu VM. I think Synology too has a Virtualisation...

That is quite clear evidence that the OTB is doing a lot more than is being instructed by Evohome.

Reliance on an Internet feed for temperature was always going to run into these sorts of issues, especially with the lag involved in the update reaching your controller.
Come on Resideo, when can we...

My OTGW sat unused for over a year and the moment I decide to sell it, because it made little sense to my setup, I could do with one - Typical isn't it.
In any case, what I was trying to do was...

So previously, Evohome would request the boiler stats from the OTB every 5mins. It doesn't do that any more. It used to request the Control Setpoint and Flame status every minute, it doesn't do that...

The Evohome firmware upgrade cannot impact the frequency at which the OTB requests the boiler for the outside temperature. It could however be that the two OTB units that you have, have different OTB...

So we think both 08: and 31: are Jasper products?

Very interesting. Could you please show me some more of these temperature messages, especially if you have the actual temperatures too. And definitely when the temperature is above 16C outside.

Kevin, are you saying you have actually seen the OTB request the outside temperature ID: 1B from the boiler? I wonder why it does that thought. That data is going nowhere. Evohome wasn't pulling it...

BTW, I too catch this type of device with exactly that message. But in my case I know it is a neighbour because I know the IDs of relays and it isn't talking to any of them.

I am getting back data from my Outdoor sensor, which seems to change exactly in relation to the actual temperature but I can't make any sense of the data I am getting.
So I am trying to figure out...

Try sending this using your HGI80, replace the xxxx with your own ID. And post what comes back.

RQ --- 18:00xxxx 31:004811 --:------ 10E0 001 00

But surely you know if 13:077615 is yours or not.

It could a neighbour's device. Unless you saying that 13:077615 is definitely yours.
According to me 31 is a wireless stat and might not even be called Honeywell.
And in any case it can't be the...

I can see how weather compensation could work against Optimisation especially with a BDR91 boiler relay. But my experience of Optimisation shows that the Optimisation periods are quite long so any...

No one with this configuration on the forum?

A lot of the firmware threads start becoming "digs" at Honeywell/Resideo and I am one of the biggest culprits.

So this one will try to be different.

I like the Cold Weather boost, especially...

Domoticz becomes super handy with Evohome but only if you have an HGI80 or similar.

10C in OT generally means OFF. So I didn't think you have to do anything specific to make the boiler go off with a 10C target temperature. Unless you are saying that your 10C target is not sticking...

It should update automatically but it's often not a bad idea to contact Resideo and get them to push the latest update to you.
You can see the version you have by clicking Settings, then keep...

The clock running slow is an old bug. But I thought that was fixed in the more recent firmware versions

I can answer your last question. It does not.

Does the boiler allow weather compensation with OT? Check that first, because I heard that some don't.

Whole system Optimisation is a completely silly idea. It was hard enough getting Optimisation to work on individual zones using common Optimisation parameters. But the moment they took away the per...

I was the most excited when Resideo said they were going to use the locally connected Outdoor Temperature Sensor which can be accessed via the OTB for their weather compensation features. The Resideo...
