Boas.
Comprei este sensor de gás e temperatura (DG-ZXGS21) no qual é compativel com o tasmota e assim à primeira vista até parece funcionar dentro do que lhe compete.
Nisto tenho duas coisas que gostava de fazer com ele:
1ª - É possivel identificar o termometro na placa e substitui-lo? Isto porque como se vê na foto, apresenta-me um valor de 31 °C que não corresponde com a realidade.
2ª - Gostava de criar com o NodeRed alguma flow que me fosse notificando a % de gás no ar.
Deixo aqui o modelo que já tenho:
