Snektek not communicating to renogy controller

Post by randr »

I just got the snektek and verified before purchase that it indeed would work with my controller(Renogy advanced rover Li 40 Amp Mppt charge controller) But so far it cannot communicate to controller and wondering if anyone on forum has any ideas? I can connect to it via wifi no problem and even added entities to HA with no trouble so unit is working that way but all i get is "major Setback! I've Lost Contact with the Solar Controller. Verify integrity of Communication Cable." also log just shows this over and over:

Jonathan has been very helpful and this is now working after he changed code for me to the device id 255. Just updating for anyone having same issue as I did. Thanks Jonathan!
