OIP 14 Prevent heating on weekends

[ligi]

Just came in and no one was there but the thermostats where on 5.
Possible solutions:

• electronic thermostats that prevent heating on weekends
• make it part of the shutdown protocol to reduce heating when the last one leaves

Is all heating already turned off for spring/summer?

[msooseth]

Yessss! And not just weekends, but nights as well :) It's important, weekends is only 28% of the time (2/7), but night is 50% of the time (8pm-8am)! So actually more savings, even if you keep it on during the weekends ;)

There are in total the following regulators in the office:

• 4+4 on the kitchen side
• 1 in the elevator room
• 4+2 on the non-kitchen side
• 5 in the upper floor
  So a total of 20.

Here is a version that's the simplest manual system, at 25 EUR/piece.

Here is a remote-controlled Zigbee version at 36.6 EUR/piece.

If we go with the cheapest, it's 25*20=500 EUR, if we go with the smart, it's 755 EUR.

Would really like to get one with communication (ZigBee, WiFi, ..) - configuring them one by one is pain and having a communication protocol allows us more options later (like switching off the heating once the last one left the office - detected via the usage of the AccessPoints)

We discussed getting 2 of these + the ZigBee terminal:

Qiumi Zigbee Thermostat Radiator Valve, Smart Programmable Thermostat, Temperature Heater, eTRV, Alexa, Googlehome Voice Control, Plug Type is M30 x 1.5

We should try them out and then buy more of the same. Let's get 3, so we can test out zones.

What's the status of this? I think we really should get one

[msooseth]

I agree. I wanted to talk to Maurice, since he needs to approve anyway and Rose is leaving her position unfortunately. Maybe you can draft an email?

Hey, quick update - we're ordering 3 of these + the hub to test them out :)

[ligi]

Great! Did you also order the ZigBee gateway for these?

Prevent heating is also a good idea if

• When no one is using upstairs
• When everyone left the office (e.g. during night)
