Finally in terms of 💸:

800€ (extractor fan with humidistat) vs 86€ (Shelly 2PM Gen3 + 3 Shelly BLU H&T sensors)

Not only this is less expensive, but also provides more features.

Me happy 😁

Finally, my #HomeAssistant auto-discovered all these devices automatically, which gives me access to all the temperature & humidity data for free. I can also manually control the relays if I ever needed and I have the energy data on top of that.

Really, 10/10 for #shelly, absolute banger.

Naturally, I bought this + 3 Shelly BLU H&T sensors (one for each bathroom) The setup was extremelly easy, I even created my own script (because I forgot to mention but you can create scripts, which also run locally!) to manage the relays based on custom logic.

This is where #Shelly starts shinning. With the Gen3 and BLU products line, these devices can talk to each other over the protocol #BTHome.

That means a Shelly 2PM Gen3 can receive local #bluetooth communication from BLU devices and perform actions (aka #automations) LOCALLY! No other dependencies

Ok, next. How to control these relays? I could buy randoms ones, integrate them into #HomeAssistant and create some #automations. But there is a problem there: it needs HomeAssistant to run and I don't want my extractor fan unit to be dependent on that. It needs to run on its own.

I dug deeper.

Issue #1: all extractor fans had to be replaced, not only the centralised unit.

Issue #2: thanks to #1, the cost just bumped significantly. Almost 800€

I needed another solution:

I have a #HomeAssistant server. Can I control a classic low/high speed extractor fan unit? With relays, that's a yes!

My centralised bathroom extractor fans unit is dead so I've asked around for quotes. The setup in my house is 4 fans for 3 bathrooms and one toilet. The dead unit is a classic one, aka "dumb" and I wanted to put something more performant, i.e. controlled by humidistat.

That introduced few issues.

I'm currently playing with #Shelly Gen3 and BLU devices. Theses are absolutely brillant! I don't think you can get better than this for the price, the features they pack and most importantly, the fact that everything runs locally.

This is #smarthome thread, let me explain more. Buckle up! 🧵👇

I also need to debug my #octoprint setup:
1. I cannot enable SSH on my headless setup. The classic ssh file on the boot partition doesn't work, don't know why
2. The upload of gcode from #prusaslicer 2.9.0 crashes the octoprint service!! 😱 It was working fine with previous version

I also need to check and fasten all moving parts. My bed leveling is ok but I have print failures due to bed adhesion once the parts get close to the edges

Today, I've put back in service my 3d printer since our moving last May. It's all connected and up to date with #octoprint. I have however one less #RaspberryPi since I plugged one with the wrong GPIO pins. That gave me the magic smoke 😅

So we are doing #AoC at #Cloudsoft (D'uh). We have a private leaderboard (as you do) and turns out that @frogfather63.bsky.social – who is unfortunately no longer our colleague – is beating us hard!

Well played sir 🫡

I've never made the switch from Twitter to Bluesky but it's now done. Damn, I missed this social network, glad to get it back! 🤗

Will delete my Twitter account now, hold my 🍺
