Majitel\u00e9 Loxone Miniserveru Gen1 – pros\u00edm \u010dt\u011bte update uprost\u0159ed \u010dl\u00e1nku.<\/strong><\/p>\n\n\n\n

Pro Loxone produkty jsem se rozhodl 2 t\u00fddny pot\u00e9, co mi doma zabetonovali pohledov\u00e9 betonov\u00e9 stropy. M\u00e1m v nich sice „hus\u00ed krky“ pro p\u0159\u00edvody na sv\u011btla, ale bohu\u017eel, se zapu\u0161t\u011bn\u00fdmi pohybov\u00fdmi \u010didly jsem nepo\u010d\u00edtal.<\/p>\n\n\n\n

P\u0159isazen\u00e1 varianta v Air proveden\u00ed (\u010dili bez akustick\u00e9 detekce, s nutnost\u00ed m\u011bnit baterky co 2 roky) se mi jednak nel\u00edb\u00ed a jednak postr\u00e1d\u00e1 to kouzlo z\u00edsk\u00e1n\u00ed v\u00edce podstatn\u00fdch \u00fadaj\u016f, nejen pohyb.<\/p>\n\n\n\n

Mus\u00edm tedy v dom\u011b \u0159e\u0161it detekci pohybu jinou formou, zejm\u00e9na zabudov\u00e1n\u00edm mini PIR \u010didel do krabic ve zdech (\u0159\u00edk\u00e1m tomu pracovn\u011b „hn\u00edzda“, kde m\u00e1m p\u0159ivedeny 2xCAT6a kabely ze serverovny, k tomu v\u017edy i +24V a je\u0161t\u011b n\u011bjakou rezervu).<\/p>\n\n\n\n

Po x marn\u00fdch pokusech s r\u016fzn\u00fdmi \u010didly (napsal jsem na to t\u00e9ma pom\u011brn\u011b velk\u00fd rozbor ZDE) jsem skon\u010dil u tohoto proveden\u00ed:<\/p>\n\n\n\n

PIR \u010didlo z aliexpressu na 24V<\/a><\/p>\n\n\n\n

U tohoto modelu je mo\u017eno nastavit dobu „dob\u011bhu“ po ukon\u010den\u00ed posledn\u00edho pohybu (d\u00e1v\u00e1m nejkrat\u0161\u00ed \u010dili 3s) a tak\u00e9 citlivost na sv\u011btlo (d\u00e1v\u00e1m i za dne). Jin\u00fdmi slovy, oba p\u0159ep\u00edna\u010de \u00fapln\u011b doprava. To, jestli se m\u00e1 prov\u00e9st n\u011bjak\u00e1 akce a jak dlouho m\u00e1 trvat (typicky rozsv\u00edcen\u00ed) pak vyhodnocuji podle dal\u0161\u00edch parametr\u016f v Loxone. Nechci do logiky zav\u00e1d\u011bt n\u011bco z \u010didla, prost\u011b po n\u011bm chci: „sepni p\u0159i ka\u017ed\u00e9m pohybu a po jeho ukon\u010den\u00ed m\u011bj aktivn\u00ed impuls je\u0161t\u011b 3s“.<\/p>\n\n\n\n

Probl\u00e9m je, \u017ee toto \u010didlo je ur\u010deno pro p\u0159\u00edm\u00e9 p\u0159ipojen\u00ed z\u00e1t\u011b\u017ee (nap\u0159. LED p\u00e1sku), kdy +24V je p\u0159ipojeno trvale a \u010didlo sp\u00edn\u00e1 p\u0159i aktivit\u011b pouze m\u00ednus p\u00f3l. P\u0159i neaktivit\u011b nen\u00ed na v\u00fdstupu „nic“. Jin\u00fdmi slovy, pro laiky – p\u0159edstavte si, \u017ee m\u00e1te +p\u00f3l LED p\u00e1sku p\u0159ipojen\u00fd na + nap\u00e1jec\u00edho zdroje a vodi\u010d, p\u0159ipojen\u00fd na m\u00ednus nap\u00e1jec\u00edho zdroje dr\u017e\u00edte v ruce „ve vzduchu“. Jakmile dojde k pohybu, p\u0159ilo\u017e\u00edte tento vodi\u010d na m\u00ednus p\u00f3l LED p\u00e1sku a ten se rozsv\u00edt\u00ed. P\u0159esn\u011b takto funguje toto \u010didlo, ov\u0161em pro vyhodnocen\u00ed na digit\u00e1ln\u00edm vstupu Loxone (Miniserver, DI Extension nebo Multi Extension Air) je to nezpracovateln\u00e9.<\/p>\n\n\n\n

Toto \u010didlo tedy vy\u017eaduje drobnou \u00fapravu, spo\u010d\u00edvaj\u00edc\u00ed v p\u0159id\u00e1n\u00ed „pull-up“ rezistoru p\u0159\u00edmo na jeho v\u00fdstup. 4-vodi\u010dov\u00e9 proveden\u00ed (s 2-mi propojen\u00fdmi \u010derven\u00fdmi vodi\u010di s +24V) si o to p\u0159\u00edmo \u0159\u00edk\u00e1. V\u00edce o problematice pull-up rezistor\u016f rozepisuji v tomto p\u0159\u00edsp\u011bvku<\/a>.<\/p>\n\n\n\n

Budete pot\u0159ebovat rezistor 47k Ohm<\/a>, a rovn\u011b\u017e teplem smr\u0161\u0165ovac\u00ed bu\u017e\u00edrku<\/a>.<\/p>\n\n\n\n

Majitel\u00e9 Gen1 (a mo\u017en\u00e1 i p\u016fvodn\u00ed Extension, kter\u00fd jsem nikdy nem\u011bl v ruce) pot\u0159ebuj\u00ed Loxone doporu\u010dovan\u00fd rezistor 4,7k Ohm. Ostatn\u00ed za\u0159\u00edzen\u00ed (MS Gen2, MS Compact, DI Ext, Multi Ext.Air) funguj\u00ed s 47k. Vyzkou\u0161eno na v\u0161ech t\u011bchto za\u0159\u00edzen\u00edch v dennodenn\u00ed praxi).<\/p>\n\n\n\n

Update 2: Pro n\u011bkter\u00e9 aplikace, kde je vhodn\u011bj\u0161\u00ed m\u00e9n\u011b viditeln\u00e9 \u010didlo, pou\u017e\u00edv\u00e1m i tento model<\/a>. Neum\u00ed m\u011bnit dobu aktivity, ta je cca 30s, ale d\u016fle\u017eit\u011bj\u0161\u00ed je, \u017ee funguje za v\u0161ech sv\u011bteln\u00fdch podm\u00ednek a je tedy mo\u017eno v Loxone vyhodnotit, kdy reagovat a kdy ne. Postup \u00fapravy je naprosto toto\u017en\u00fd.<\/p>\n\n\n\n
