  • I just found a pattern. Monday, where it was showing up 1 hour earlier, I was connected to my M365 Cloud PC via my home Macbook. Then, the appt (only this one) showed up wrong.

    Yesterday, I was using that same Cloud PC from my work (Windows-)laptop and the appt showed up at the correct time.

    Today, I’m using the exact same Cloud PC - without rebooting - from my Macbook again and Outlook shows it wrong again.

    So, that virtual machine that’s called Cloud PC does something different depending on the system you’re connecting from. How stupid is that?



  • You’re not alone. We’re forced to use Classic Outlook at work.

    I’ve got a monthly recurring appointment for a Zoom call. That was due today again. There was the switch to winter time last week and Outlook decided to “adjust” the scheduled time for me.

    That meeting was originally for 11am and should continue to be at 11am during standard time. However, yesterday I’ve noticed that Outlook put it at 10am (and showed a proud message that it adjusted it due to timezone change). No way to undo it.

    Teams continued to show it at 11am where it belongs.

    Now, when trying to move it to 11 in Outlook, Teams moved it to 12.

    And when I opened Outlook this morning, the appt was at 11am where it belongs and Outlook and Teams agreed again.

    Mind you, this was only this external Zoom call. All other appointments are still correct. Very weird.





  • The Junkers boiler at my previous place had an emergency mode where it was heating when the contacts were open. Even their simplest thermostats put a load on the wires depending on how much heat is required - so it doesn’t go full blast when you are only slightly under the target temperature.

    So, this all depends on your specific boiler. While it might work with a simple relay, it might be far from optimal in terms of energy efficiency and wear&tear of the boiler.



  • Despite the name it’s not a simple on/off that can be done with a relay. Those 2 wires also provide power to the thermostat unit. I’d first try to find more information about how these thermostats report demand to the boiler before using a relay.

    I’ve also seen someone that simply replaced the NTC/PTC on their existing thermostat with some ESP circuit so they basically controlled what the thermostat “sees”. Want more heat? Tell the thermostat that it’s 5℃ in the room. Want the boiler to stop? Simulate a cozy 30℃.


  • That’s a Honeywell T87G1006 “On/Off” thermostat. “On/Off” meaning that it can signal to the boiler whether more heat is needed or not. Boilers of that time may also be compatible with the OpenTherm protocol as there’s a similar model that also speaks OpenTherm.

    The easiest way to go about this is probably to look for a more modern thermostat that’s compatible with your boiler but also provides some interface for remote control from your Home Assistant.
