My brother has one emonpi and he wants to measure the temperature of the solar thermal panel.
He talk with the local installer about sensors he could use to monitor and the local installer asked what Ω have emonpi and ds18b20.
From what i have reading but never get sure, DS18b20 has 100Ω, am i correct?
Can you give-me an idea of what sensors could i connect to emonpi or if the ds18b20 is suitable for my purpose?
This is the type of solar panel that my brother has.( but not the exact model).
It has integrated water reservoir inside it.
If it would be me, i would use a esphome node-mcu with compatible sensor to transmit to emonpi by mqtt but my brother wants everything integrated, so why i ask this.
Thanks in advance!
