Anyone else out there having trouble with the #honeywell #evohome app for heating control? Ours has been playing up for a few days now: seems to be reporting room temps properly, but not set points. Any attempt to change set points or schedules doesn’t seem to get passed to the controller 🤨

Official Honeywell APP displaying current system state has the same behaviour so it may be some problem with data send from main unit to Honeywell. Anyway - because of lack of system data (missing info about boiler on/off for example) it is impossible to figure out when system is asking for heat - difference between temperature and targetHeatTemperature is untrustworthy. 😠

You can see yellow line of current temperature reflecting state and is scheduled at the main unit - 1: stop heating, 2: prepare to be heated to 20° at 3, 3: be at 20°, 4: heat to 21°. But the gray line of targetHeatTemperature stays all the time unaffected at 21° except of while when systems smart fn asked for unscheduled value to prepare room for point 3.

Honeywell API useless for deeper stats?
While prepairing my own simple Evohome heating monitor I found out some annoying problems with data given by HW API. It seems that in some cases API doesn't reflect main unit state and schedule correctly and "keeps" zones targetHeatTemperature unchanged nevermind the current state displayed and realized by main unit. Look at image in next toot to view problematic situation.

Stressed by missing Honeywell Evohome system statistics (wonder what it is doing when I'm not watching it) I wrote small PHP monitor for collecting system basic states and displaying graphs. When finished first version, system stopped to return correct target heating temperatures so my latest graphs are not valid.
Maybe this could be the main problem of missing HW stats - we cannot be sure our data are correct. But be lucky, your home hardware is working well :-/ #honeywell #evohome

Somebody here keen in settings and management of Honeywell Evohome? Help. I need somebody! 😠
