Kedze sa chytili zatial len "nasi", budem pokracovat po nasom...
ZigBee (pripadne najrozsirenejsia implementacia XBee) ma zaujalo uz pred
vyse rokom. Velky vyber modulov, dostupna dokumentacia pre koderov...
Kedze s jednocipakmi som sa naposledy hral pred 20 rokmi, tazko sa mi bude
naskakovat naspat do tohoto vlaku. Hranie s *duinami ma zatial nelaka, tak
isto hromadny nakup Rpi ku kazdej zasuvke.
Ked som hladal hotove vyrobky, pre ZigBee toho moc nie je a ked je, je to
vacsinou pre amerikanske zasuvky.
Z-wave som tak akosi prehliadal, pretoze som bol zahackovany na ZigBee.
Az som natrafil na tento produkt:
http://www.fibaro.com/en/the-fibaro-system/wall-plug
Z mojho pohladu je to killer aplikacia, pretoze nemusim rozmontovavat
ziadne zasuvky (aj ked to mi ziaden problem nerobi). Mozem zacat prakticky
len s meranim spotreby 2-3 spotrebicov v domacnosti (a to je moj primarny
ciel "home automation"). Ked som nasledne hladal veci okolo Z-wave, nasiel
som aj ine vyrobky (spinace/stmievace do vypinacovych krabic, zasuviek,
dverne snimace - dokonca kombinovane s inymi velicinami) a ich ponuka mi
pride lepsia - hlavne pre nase europske nasadenie - ako u ZigBee.
Dokonca aj USB riadiacich modulov kompatibilnych s Linuxom mi pride lepsia
ponuka.
To, ze cipy vyraba jeden vendor - ano, pohladu "free world" - je zle
a hnusne a kryptofasisticke, ale zasa mam vacsiu istotu, ze mi vyrobky
viacerych vendorov budu spolupracovat (co u ZigBee vraj az taka
samozrejmost nie je). Je mi jasne, ze si musim davat pozor, aby som kupil
vyrobok s nasim RF pasmom.
Teraz mi vlastne ide len o to, ci som nahodou v tej zaplave hype
prezentacii k Z-wave vyrobkom neprehliadol nieco, kvoli comu si neskor
budem buchat hlavu o stenu (slabe sifrovanie, silne rusenie s TV a
pod,...). Takze ma zaujimalo, ci uz niekto z vas nevychytal slepe cestu
a usetrim mi cas, peniaze a nastvanost mojej manzelky. :-)))
Diky.
P.S. Som si spomenul, ze zatial ma zarazilo len jedno - v navodoch k Z-wave
vyrobkom je vzdy parovanie riesenie ako: vytiahnut riadiaci USB kluc z
PCdla/servra, zmacknut na nom tlacitko, zmacknut tlacitko na novom module a
cakat, kym ledky neohlasia sparovanie. To neexistuje ziadne softverove
discovery bez nutnosti downtime uz existujucej infrastruktury?
