TRV losing contact with internet bridge triggering boiler?

bluezetc

I haven't quite worked this one out but I occasionally find the boiler operating when no rooms are calling for heat. I know this because I have a couple or radiators that don't have TRVs and I notice they have heated.

I have a wired Smart Thermostat in the entrance hall and five rooms with Smart TRVs on the rads. The room furthest from the bridge occasionally loses contact and either at that point or when it re-connects it appears to trigger the boiler firing even though it isn't below the set temperature.

Anybody experienced anything like this?

The rads that heat are in the hallway and when I notice this I have checked the app and the rads in each of the controlled rooms and none are calling for heat or heating. Strange, and because it only occurs occasionally, I haven't got enough instances to be sure something hasn't just stopped calling for heat.

Not a big issue, but I'm intrigued.

Yes! I had this a couple of months ago. We typically have our TRV's set to frost protection during the day and I'd been stood in our utility room and the boiler kicked in. App showed all radiators were off, yet the couple we had without tado TRV were warmed up.

It happened on multiple occasions.

I did raise a couple of support tickets to Tado and suggestions were 1) reboot everything and 2) check batteries in the TRV as if one unit is dead it could cause a call for heat .. hmmm

Anyway, I haven't seen this for probably 3-4 weeks now so I'm not sure if a software update may have fixed it.

Yeah same all my rads have smart TRVs but our towel rail doesn't and that was randomly heating up when all TRVs were off. Eventually I got a longer ethernet cable so my bridge is now further from the router and have stood the bridge in an upright position and the issue seems to have stopped for now. The USB connection to the bridge seems to be a bit loose so I wonder if that was causing disconnections which resulted in calls for heat when reconnecting. Now it is upright the cable doesn't seem as liable to move. Not sure if that will solve the issue for everyone but worth a try maybe

Thanks for the replies - good to know I'm not imagining the issue.

I also re-located the internet bridge using a powerline ethernet link and loss of contact happens rarely now so haven't noticed boiler firing without call for heat or maybe, as Paul0000 suggests, there has been a softwareupdate.

HI

Boiler firing when in Away mode and all thermostats showing “ Frost Protection”.

This is exactly what I have been concerned about but as of now ii still have not had it sorted by Tado support.

Boiler coming on burning fuel when technically away from home.

Needless to say that if , for example , I was away for a period of time would be a complete waste of money.

I have been having this issue since installing TRV's but as of now still nothing really explained nor sorted. I am having to cut the power supply to the boiler.
