Hello all,
I fancy a new project and B4R is interesting. I'm thinking about measuring the temperature of the household hot water system (sensors clamped to copper pipes on the water tank). Maybe it we help to understand how long the water remains hot and means the gas boiler might have to switch on a little less this winter. It will be interesting to see times to heat up, peak temperature and the time for the temperature to decay. The project I'd like to build with my daughter (we already have a lot of fun with B4J and B4A) and I'm going to make a rule that it MUST be powered from a renewable power source (once we've got something on the bench working). We can play with solar + battery charging etc, maybe wind.
I'm thinking ESP32 + multiple
How do I choose which ESP32 board to use? There seems to be 1000000000000000000 versions available. I'm concerned that I go ahead and buy something that later I find is not 100% correct to use with B4R. Would...
