Thanks and great questions 1+2 - the S30 only sends diagnostic data when the diag level is non-zero. So yes, when the diag level is zero those entities are unavailable. |

Had a power flicker last night, reset the S30 and then this morning notices diags were turned off, so I think that problem needs solving. An approach is to create a automation that detects that the sysuptime has reset, meaning the new value is less than the old value, then set the diagLevel back to 2. |

This (older) S30 tips document seems to imply it uses RS-485. I'm not sure if this is still true. https://www.scribd.com/document/555169180/LENNOX-iComfort-S30-Troubleshooting-Tips But RS-485/USB dongles are pretty cheap and I may try it myself. |

Hello. I am very pleased to find this excellent integration. Our 25-year-old dual up and down 2.5/3 ton systems finally died a few weeks ago and we now have a brand new installation of a three-zone 5-ton variable speed AC two stage heat Lennox system.
OU: SL28XCV-060
IU: SL280UH090V60C
Zone: iComfort DCM
Thermostat: S30
Zone sensors: 17A30
While I am still staggering under the cost of having something the price of a minivan in my attic, we are loving it so far.
Some questions, though, about this integration.
I know that was a lot of questions. I really appreciate the HA community and in particular all the work that went into this Lennox integration. I will find the donation link and put some coin there. And I will be very willing to send any logs or participate in any testing needed, particularly if there are things you want to try on my latest hardware from Lennox.
Thanks/Nathan
