Jag snickrar på ett system som jag tänkte sätta upp på vår liftstuga
Jag är med i arbetsstyrkan vid den lokala Friluftsfrämjandet och vi har köldgränser som påverkar öppethållandet. För att ge bättre service OCH slippa åka dit för att kolla tempen, tänke jag bygga ett system.
Jag tänkte basera det på en Wemos D1 mini, Ai thinkers A6 GSM/GPRS modul och en (till att börja med) 18B20 one-wire prob.
Så här har jag kopplat ihop hårdvaran:

}Ska kanske sägas att jag inte kodar till yrket, så min "stil" kan nog lämna en del att önska. Dessutom är behöver den lite TLC, för jag får bara rätt svar OK! (temp) kanske i hälften av fallen.
