Hi, thanks for the reply. I’m using station MID_E0424, others in Calgary behave the same way. I noticed that on wx.aerisweather.com the forecasts were also way off (for all the Canadian cities I tried). I contacted their support and they replied:
Thanks, the core issue was tied to one of the Canadian models that was being utilized, it had a bad data run. The short term solution we have removed this model, which has helped the forecasts match closer.
So it looks like they had an issue on their end that they’ve temporarily fixed. It might be worth a follow-up from the Rachio team, since the Aeris weather is critical the Rachio service working properly.
