Ja neviem mozno ze to bude offtopic ak som nepochopil temu tak sa ospravedlnujem.
Ale ked som riesil ovladanie zasuviek na dialku najlepsim riesenim mi prislo kupit si 433 Mhz vysielac/prijimac z ebay alebo z ciny (investicia do 150 Kc). Napriklad: http://dx.com/p/433mhz-rf-transmitter-receiver-link-kit-green-221225
Nasledne som pouzival najlacnejsie spotrebice (zasuvky, vypinace, stmievace, cidla teploty) pracujuce na 433 Mhz (ceny tiez radovo v 100 korunach), maju ich vsade mozne.
Co sa tyka samotneho softveru nieje problem si to nabastlit pripadne vyuzit nieco hotove: http://www.pilight.org/
Z-wave a podobne mi prisli zbytocne drahe a obmedzujuce.

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?
