With some home repair-and-fixup work going on, I'm working in the attic for a few jobs lately. I'm trying to avoid sunny days and the associated temperature extremes.
Was up there for an hour or two this morning, and moved a #Zigbee temp/humidity sensor up. Don't know why I didn't think of that earlier.
#HomeAssistant tells me it's currently 38C now, so I'm glad I haven't been up this afternoon.
Für mein #SmartHome Projekt habe ich einen #Zigbee USB Stick bestellt – reichelt hat ihn in einem „kleinen Karton“ geliefert.
Kleines #WLED Projekt bringt endlich Licht an den Badspiegel. Seit 3 Jahren hingen da Drähte über den Spiegel und ich habe keine vernünftige Lampe gefunden. Also von AliExpress fertige WLED Platine, BTF Led Stripes (IP65), ein Netzteil. Von Amazon die Profile. Vom Baumarkt Wandsteckdose, zwei Regalbretter, kleinere Sachen zum Befestigen. Etwas Löten, etwas Bohren, zurechtsägen, an die Wand pinnen fertig. WLED konfiguriert. Nun nur noch #Homeassistant mit Schalter verheiraten (#Zigbee).
I wonder if I could minimize my Zigbee light controller even more. Right now it's on a Raspberry Pi Zero with a Zignee USB dongle but what if I could do it with an Arduino... 
@TomasHelleberg kör temp/luftfuktighetsmätare med #ZigBee lite överallt (olika rum, vind, krypgrund). För att få mottagning har jag några ZigBee enheter i eluttag som då fungerar som routrar för signalerna. Mätningarna tas emot av en ZigBee USB-sticka på en #RaspberryPi som kör #HomeAssistant som sparar datan och kan presenter historik och grafer osv.
My #HomeLab has grown way beyond the clean and simple setup from 1.5 years ago. Time to optimize — but let’s be real, a HomeLab is never done.
Replaced old 1950s receptacle w new one. Added clamp-on current sensors out to a #Zigbee unit in a separate (plastic) box to contact #HomeAssistant.
Broke the tab off to split the receptacle and applied sensors to track dehumidifier and sump pump separately.
Needed a sensor flip to fix current dir, but it works nicely now. I get an email if the pump comes on!
Only in the house 6mo or so, and don't think the sump pump has run yet. We'll see how spring goes – probably the riskiest period.
This is the little 2channel #zigbee monitor I'm using. Looks like lots of people using something similar. It has two current sensor clamps, so it's nicely non invasive.
Not wild about it using 120V power as a battery or an adapter would prob be safer, but I've put the thing in a utility box to keep the 120V supply lines safely covered.
Can sense up to 80A of current
Learning more than I'd hoped was necessary about the #HomeAssistant #zigbee device handling.
There are python add-ons called "Quirks" that let devices add sensor entities after the fact for ZHA and Z2m.
I've got a 2-channel power sensor I'm trying to add and it seems to be on the bleeding edge of supported devices.
I see dev work going on, so might be the easiest path forward is to wait a few weeks.
But hey, I learned about Quirks today, so that's a new corner of HA for me.
Signify/Hue: "Yes, we sell expensive gradient light strips and extensions. People love our stuff. It just works."
"Do they love us too much though? That's a bit unfair to other manufacturers, no?"
"You're right. What do you propose?"
"Let's make the extension connectors really flimsy and short, and the strips curl."
"Brilliant."
I'm automating stuff at the family farm using #homeassistant ; lights, smoke alarms, stove fire preventers, heaters.
It's inspiring to see so many iot devices support #ZigBee but also infuriating that 50% of the ones I've encountered has something fucky with their zigbee implementation. It's also somewhat concerning that the mains-connected zb router devices I've found will drop off immediately when the power goes out. The thought of not getting alerts about a fire in the barn if the power's out, concerns me.
I've got my eye on #matter , but I can't find compatible smoke alarms in Norway (so I can be confident they comply with local regulations, and return them if they're bad), and only limited reviews of ones available from abroad.
I see there's https://www.matteralpha.com/category/smoke-co-alarm and https://community.home-assistant.io/t/smoke-detector-with-matter-over-thread-support/810731 but idk.
Can anyone recommend a mains-powered zigbee router device with a built-in battery, that'll keep it routing for at least 1 hour if it loses power?
Alternatively, a small (max 20*10*10cm) #ups that'll power a zb router or other tiny device for 1 hour? #NUT #networkUpsTools compatibility is a big plus
Bought some cheap-ass temp/humidity Bluetooth sensors from Xiaomi, was very happy to discover that the hardware also supports Zigbee, proceeded to immediately flash the wrong firmware file and bricked the whole thing 
Time to break out the JTAG 
Oha, die #ShellyGen4 mit #Zigbee sind jetzt verfügbar. 
https://www.shelly.com/de/collections/all-products/gen4
Fehlt nur noch der #2PMGen4 
Gibt es #homeassistant kompatible (bsp. #Zigbee ) #SmartPlugs mit Schweizer #T13 Anschluss, die auch den aktuellen Stromverbrauch ausgeben? Weiss da jemand was?
Sniffing Zigbee traffic sounds complicated? In my latest guide, I show how to capture and analyze Zigbee communication using Wireshark, ember-zli, and an EFR32-based sniffer.
Learn how to decrypt packets, explore ZCL commands, and troubleshoot issues in your ZHA or Zigbee2MQTT network with confidence.
Ideal for Home Assistant power users & tinkerers!

When I thought "Oh these Busch-Jaeger wall Zigbee switches haven't had an update to their firmware since 2016, I should replace them sometime" I did not mean "they should physically fail the very week so I am forced to buy new stuff" 
Gerade kam Nachschub für das heimische Zigbee-Mesh.
Dites les fans de domotique,
J'ai en tête l'idée de contrôler ma chaudière via Homme Assistant. L'idée est de l'activée ou non en fonction de ma présence dans une pièce.
J'ai en tête de trouver un thermostat connecté déporté que je mettrai là où je suis. Comme ça, je ne chauffe vraiment qu'une pièce en fonction de mes besoins.
Bonne idée ? Mauvaise idée ? Du matériel à recommander ?
