i have a Pi Zero and the Solarpackage with 3,7V LiPo.
Q1: is it correct that according to the instructions the wiring is done once into the I2C bus and once (disconnected white cable) into the D4 digital input? In the manual there were two possible channels D6...
Does "pat the dog" work automatically within the SkyWeather scripts or does "pat the dog" belong into rc.local?
Q2: how is the hysteresis set or can it be adjusted? My LiPo package has an additional BMS. (I'm afraid that both might get in the way and the BMS will cut the current directly at the battery before the SkyWeather BMS will shut down the Pi cleanly).

Q1: i think i got it... "pat the dog" is a function in the SkyWeather scripts and if i disconnected white cable = enables the use of d4/d5 and d5/d6 - english is not my mother tongue and I had read it wrong in the pdf... everything works better in peace and quiet.
The following connections (besides the power supply) are occupied: - Grove USB Control - PulseHi / RESETIN - Grove I2C - PiWeather BUS2
- Grove WatchDog done wake - D4/5
Is that right?
Q2: no SolarMax - I use a Li-Ion battery 3.7V 8400mAh with onboard battery management system (BMS): 3.7V nominal voltage, 4.2V charge cut-off, 2.65V discharge cut-off.
Which values are used by the suncontrol board? These are permanently programmed or stored in a configuration file?

Q1 is the question of the correct wiring of the individual components. I guess it's OK.
Q3: So far I have started SkyWeather manually from the console. Now I want to start the station automatically while booting. Unfortunately the following happens now. The station boots up, but is slowed down exactly after 64 seconds and starts again. I know that it is the WatchDog. But it is fed too late. At what point can I feed it so that the station does not run into the timeout and thus into the reset?
