  • I wrote it to automate my workflow - I’m in sales. I enter site details at the customer location and my app crunches the numbers to pre-fill all relevant documents (contract, financing, etc) in PDF form. I also use it as a presentation device to explain service and product details/specs using pictures, videos and PDF documents.

    No more paper, no more fiddling around with calculator and rate-cards. I do a little data entry and basically my job is done.








  • You are wise to be concerned but I think you will not design an “enclosure” that will prevent further damage if it is inside a wood frame house. There is a house near me that burned down because of a single power brick for a tool in the garage.

    Your better approach would be to make it so that power delivery is monitored and regulated automatically. That or manually just unplug after charging.

    Thermal runaway happens on over-discharge or overcharge of the battery pack. Each pack has smart circuits to regulate this but they are designed at scale with a squinty eye at overall product cost…cheapest circuit available gets used even by well-known manufacturers.

    Place power draw monitoring on the delivery circuit and when the draw lowers to maintenance level (batteries have recharged) have the power delivery automatically cut off. This can all be automated with freely available smart home products. You can even get some temperature sensors to monitor for overheat conditions during charging.



  • What you’re looking for is a Shelly relay. I have some wired into switches for various things. For your situation you would put the relay in “detached” mode so the physical switch is not actually switching power but the relay can use the switching action to trigger the automation to the bulbs. The bulbs are always supplied power but the switch can control their state.
