All things Shelly

I see Shelly have finally released their Circuit Breakers as well, and they're not horribly horribly priced either.

Contemplating whether its a worthwhile investment or not at this point.

Sorry, forgot to post a link... but yeah those.

Obviously there could be legal issues with using them, so I'm just contemplating it atm.
 
How reliable is the Shelly PM mini gen3? I want to install one of them on my heat pump to measure electricity consumption.
Reason I ask, because it's connected in series with the appliance, if the Shelly fails, the heat pump will stop working and as is my luck, this will happen while I'm not at home for a week and then I have to deal with the fallout.

My thinking was actually to install the Shelly at the heat pumps change over switch, but only on the heat pump side, so if the Shelly fails, then the normal geyser element will still work if flipping the change over switch. I never use the electric element anymore since I installed a heat pump, so it won't bother me if there is no energy monitoring on the element.
I must still check if there will be space in the change over switch enclosure for the Shelly.

I can’t speak for the gen 3 - but I suspect they’d be more robust than the gen 1 that I’ve had for 5 or 6 years.

Aside from the Shelly 2.5 which died after 4 years, the others are still running (1 / 1PM / Dimmer 2)

Why not use a Shelly EM and then it uses the clamp to monitor usage. This way if the shelly fails your heat pump wont be affected.
I got my uncle a Shelly EM with two clamps, one for his borehole pump and the other for his water tank pump. He wanted to have a record of when they came on and off, but he also can see the power usage of either.
