Bridge lost internet connection a 4 am and required manual power reboot

Hi,

I’m new to tado (installed it this week).
Since Monday the bridge worked fine (i don’t think it likes DPL networks, but that’s another post). I think the bridge was always online, but didn’t pay attention to the temperature stats etc. until tado support got back to me (yesterday) for completing the boiler install to the Smart Thermostat.

Anyway, since completing the installation yesterday, I set up schedules, etc., then went to bed.

When I woke up this morning, the radiators had remained on their last scheduled temperature of their current setting when the bridge stopped connecting to the tado servers (so it was cold).

Initially, of course, I didn’t realize why it was cold, then after seeing the tado app (iOS and web page), I realized everything was offline. At this point I checked the bridge, where I noticed that the internet LED was blinking. However, all my other internet connected devices (smart lights, google home, iPhone, computer) were all connected.

I hard rebooted the bridge (i.e. disconnected then reconnected the power). I did NOT hard reboot my internet router (as I had internet connectivity when I woke up). At this point the bridge came back online (internet status LED was solid), and it took a bit of time for each of the smart radiator thermostats to come back online. On some I turned their dial, while others I didn’t. I assume they just take a bit of time to come back online after manually hard rebooting the bridge.

Checking the temperature logs, I deduce that the bridge stopped communicating at around 04h00.

After all the description above, my questions to tado (and other experienced ‘users’) are:

- why did the bridge stop connecting at around 04h00 (see also second question) ?

- is there a way to check logs on the bridge to understand why it stopped connecting (because maybe tado servers were down or my internet connection temporarily died) ?

- if the tado bridge does create logs, can we access those logs, and custom configure the bridge to connect you our own log server (some people have Synology NAS devices for example which has logging software for other devices) ?

- why did the bridge not come back up after the unknown event at approximately 04h00 (all my other internet devices were online in the morning) ?

- from my experience described above, I conclude that the smart radiator thermostats do NOT store any scheduling information locally in order to change the temperature at a scheduled time for the cases the bridge goes down — they, instead (maybe for design reasons for manual override functionality (I think not the reason)) they NEED an online connection via the bridge to change a scheduled temperature ?

- if thermostats do NEED to be online to change a scheduled temperature, then

a. Is there a plan to improve their functionality via a SW/FW update so they can locally store schedules and not depend on online bridge connectivity ?

- if the answer to sub question b a one is no, then could it be possible to have a multiple bridge configuration (two, three, etc.) for redundancy purposes (e.g. bridges go down, and one fails to come back up, but the second one takes over the online control role to keep the thermostats respecting their schedules) ?

P.S. if the bridges could be made to always come back up (except if they are really dead), then a redundancy feature would only be needed for bridge hardware death events.

With Well Wishes,
