Gizmo Posted September 27 Share Posted September 27 (edited) Hi guys, I am looking at using Shelly for a small commercial project and the initial thought was using the Pro 1 & 4PM because of the LAN connectivity, I've tested the units and they work great. The problem is that the client is now changing their mind and saying that LAN may not be an option and asking could we use Shelly Plus 1PM fitted behind the sockets. There will be around 50 sockets that need controlling. My question is, what is the difference between the PRO and non-Pro Shelly switches? If we exclude the convenience elements (LAN, rail mounting, physical buttons...) is there any other major difference in the hardware that would make the PRO PM more reliable than the Plus 1PM? The cost is not an issue in this case, just reliability. Many thanks Edited September 27 by Gizmo Quote Translate Revert translation?

Members thgoebel Posted September 27 Members Share Posted September 27 The volume of âproâ devices is generally larger as with devices of âplusâ series. Especially the Shelly plus 2PM has a very dense package due to the amount of electronic parts it houses. Thus, the inside temperature of âproâ devices will be slightly lower as with âplusâ devices, which has an impact to the reliability. 1 Quote Translate Revert translation?

Heinz Posted September 30 Share Posted September 30 As mentioned the only thing is the size and temp of the device. The functionality will remain the same as the Pro device. One point to keep in mind is the Generation of the device as gen 2 "Plus" and Gen 3 have moved flash memory and an other chip that is a bit faster. Quote Translate Revert translation?
