Here's the deal. You share with me why you are the perfect candidate to receive a free ticket to Do iOS in November. On behalf of @Guardsquare we can allocate 2 tickets to the perfect candidates.

Suggesting another person is also ok. DM, reply, email, any channel is ok.

Big shoutout to @hedge.co. The first company to send a team of 5 or more colleagues to Do iOS! Who can top them?

Like by sending your team to the workshops too maybe?

Welcome Hedge. Make sure to talk to them at the conf. THeir products look super interesting.

It is actually a fan control unit that allows one to attach up to 12 fans to a radiator. But it works perfectly as well for monitoring input and return temps.

HeatBooster - de slimmere radiatorventilator / by SDR Engineering Slimme aansturing voor radiatorventilatoren. Geschikt voor koelen en verwarmen. Verminderd het energieverbruik. Smart Home functies met MQTT en Home Assistant.

And I got an SDR Heatbooster as a measuring unit with sensors tie wrapped to the pipework near my heater. The return sensor not too close to the heating unit to prevent influence by heat being conducted through the return pipe itself from the unit.

I left a rather large comment on why you are seeing lower gas usage with a lower input flow temp. :)

I hope it explain a lot on why you are getting the results you are seeing.

Seems like I ran into some bug in the new Final Cut Pro.

Jumped into a forum post with an Apple engineer, offering my problematic project. Just uploaded 75GB+ to facilitate that.

Edited @felibe444.bsky.social, rendering that one tomorrow.

Yeah but bribing her. That would be impossible for @stefanblos.com or me, even if we would take out an extra mortgage on our homes.
