Hi. Sorry if I missed replying to you. If anyone still interested in the 3000's, send me a direct message and we can take it from there.

SOH read from the batteries via Terminal. Uploaded for those interested.

Thank you for the info. I just used Battery view to get the battery charge cycles. I will do as you suggest. Can only do it on Saturday.

Great work Jacques!

We did some investigation. The Jhb warehouse brought some to check. Someone imported a container load full of used train batteries. They come from China and India. Apparently they are replaced every 5 years. The guys selling them are brokering the batteries and getting a cut - they don't own them. What we looked at had the branding spray painted out. Said they did have new units and would come back, but we have not seen them since.

Hi. You can use a DS18B20 thermo sensor to replace the thermostat. You can then measure and control using Sonoff th or Wemos on Home Assistant. You could probably connect it directly to the Pi GPIO.
