Tesla Powerwall 3: Powerwall shuts down from overheating

Thu, 14 Aug 2025 22:44:44 -0700

Does anyone know how I can get access to the Powerwall data? I suspect it should be by an app and wireless data transfer. I have asked Tesla for access to MY data but have not received an answer yet

Electrical: Digital Caliper not outputting a clock

My digital caliper from Harbor Freight does not output the clock signal at the connector.

My digital indicator performs like the blogs. Any ideas on what happened to the clock signal? The calipers are brand new with a fresh battery

Electrical: Paradox alarm security system setup

Mon, 03 Dec 2018 12:46:38 -0700

System parts: Paradox SP4000 + K10V keypad + Paradox DG65 motion sensors + siren (AMC Blade 01) + 45VA transformer + Accu (x2)

Two main issues need resolution please:

1) After connected all wires and plugged into the wall only the TBL button is flashing on the keypad and no status LEDs are on at all on the keypad. If I push TBL button that results nothing, no other button lights up. I cannot step into maintenance mode or any other modes. Cannot do anything with the keypad. What could be the issue?

Keypad is properly wired according to the installer guide. Transformer is giving 18.8 V into AC input. Checked it.

2) The siren is a basic one with 5 separate outputs:

supply +

supply -

S (alarm terminal)

tamper (anti-opening)

tamper (tearing off)

If you have the knowledge would you please share which output of the siren should be connected into which input on the paradox central panel? Supply + and – is clear but should I connect the S (alarm terminal) ? And where should I connect the two tampers in order to be in operation correctly in case of any tampering situation?

Appreciate any help

Thank you

Electrical: Dimplex 4 Zone Wall Mounted Pilot Wire Controller (Model No. RXPW4)

Sun, 19 Aug 2018 16:14:27 -0700

Hello!

I moved to new flat and all energy is for electricity. In the flat is water tank with a timer and it is getting warm during the night for low cost energy tariff.

I found out that there is also some storage heaters controller. It seems that the controller is not working. It seems burned. I do not know when was the controller installed, probably when the flat was build (2005).

My questions are… Is it cheaper to call Dimplex and ask for their electrician or shall I found someone by myself? Is the controller really burned? There is some switch. Is it for the controller?

The bill for 3 months was quite big despite I did not really stayed in the flat for one month. I am on the cheapest tariff which I can get. Is it logical to switch the water tank timer every second night as, I assume, we do not spend all the hot water and the tank should be insulated…

I am also wondering for what are the switchers next to the storage heaters?

I am attaching a pictures.

Thank you for answers!
