Connecting the Sensors with the external power over 5V
I did not find anywhere information or schemes for connecting a water level sensor.
There is no instruction (probably not very popular) and in the description of it you also have no information.
The fact is that its power supply is 24 V, the output is 0-10 V.
But how to connect it correctly to the D105?

Подключение 2 датчиков DHT22 или DHT22+D280
А с чем связано ограничение на подключение 2 датчиков DHT22 или DHT22+D280? В меню могу выбрать только один. Хотел бы измерять температуру и влажность внутри квартиры (дома) и снаружи + давление снаружи. По идеи эти датчики работают по общей шине 1 wire. Заодно не помешало бы пара DS18x20. А так нужно наверное на каждый датчик ставить D-105, т.е. при моих "хотелках" нужно 3 штуки?

Hysteresis in relay management
Good afternoon! It is possible to activate the function on the switching and off of the relay on condition with Hysteresis, as when working D105 with the CO2 sensor there are sharp fluctuations of readings and as a result false positives of the relay and frequent switches and disabling mechanisms.
