IMHO - I can't see much reduction here? tado° technically requires an internet connection and its servers run 24h, does anyone consider this? tado° is not only a back end, but also a front end.
In my case, I honestly see no CO2 reduction. The setup is simple: if > then. No geofencing, no complex logic. The old so-called dumb thermostat offered the same function but without the need for the internet. There are of course advantages such as convenience, remote access etc, but these are not part of this discussion.
CO2 is again widely used as a sales thing to persuade customers to buy products, but on many occasions its just an ideology not supported by real benefits if you start looking into the details, not just marketing leaflets.
Start by calculating the in-life CO2 footprint at circa 0.2 kg CO2 per kWh of natural gas. Our 45% annual kWh natural gas saving equates to a CO2 footprint reduction of circa 250kG for every Tado Smart TRV. The production footprint of Tado devices is probably negligible compared to the in-life reduction.
@TropicalRalphie Well done Ralphie! Your 50% reduction helps to confirm that our 45% annual saving is not an 'outlier'! We too use geofencing a lot. I'm sat here at 17 deg C in the study while its -1.2 deg C outside.
